If you want to contribute, it's a +good idea to read this document. Although the file is called *contributing*, it +describes the whole release and development process. + +## Bug tracker + +The bug tracker is hosted on [Github](https://github.com/rsnapshot/rsnapshot/issues). Please don't report any issues in the tracker on Sourceforge. + +## Source code control + +The rsnapshot source code is on [Github](https://github.com/rsnapshot/rsnapshot). + +Auto-generated files should not get tracked. If you need the configure-script, generate it with `./autogen.sh`. Keep in mind that you have to execute `./autoclean.sh` before you commit. + +## Opening Issues + +If you have found a bug, open an issue-report on Github. Before you open a report, please search if there are corresponding issues already opened or whether the bug has already been fixed on the `master` branch. Please provide the rsnapshot-version, and describe how to reproduce the bug. It would be great if you could provide also a fix. + +## Building rsnapshot + +If you checked rsnapshot out of the git-repository, you have to generate the configure-script with: + + $ ./autogen.sh + +rsnapshot uses the common triple to build software: + + $ ./configure + $ make + $ make install + +## Development + +The `master` branch should be complete, by which we mean that there should be no half-completed features in it. Any development should be done in a separate branch, each of them containing only a single feature or bugfix. + +![The branch-model in general](./contrib/branchtree.svg?raw=true) + +### Coding standards + +Changes that do not conform to the coding standard will not be accepted. The current coding standard is primarily encapsulated in the code itself. However briefly: + + * Use tabs not white space. + * There should be no trailing white space on any lines. + * The soft line length limited should be 80 characters. + +### Adding features + +Fork the repository and open a new branch prefixed with `feature/`. Keep the name short and descriptive. Before opening a Pull-Request against the main repository, make sure that: + + * you have written tests, which test the functionality + * all the tests pass + * your commits are logically ordered + * your commits are clean + +If it is not the case, please rebase/revise your branch. When you're finished you can create a pull request. Your changes will then be reviewed by a team member, before they can get merged into `master`. + +### Documentation + +We very much welcome improvements to the documentation. It lives in two places. First, the program itself is +documented in this repository. Second, the website [rsnapshot.org](https://rsnapshot.org) lives in a separate +[Git repository](https://github.com/rsnapshot/rsnapshot.github.io). + +### Fixing Bugs + +Create a new branch, prefix it with `issue/` and, if available, the github issue number. (e.g. `issue/35-umount-lvm`). + +Add your commits to the branch. They should be logically ordered and clean. Rebase them, if neccessary. Make sure that `make test` passes. Finished? Open a pull-request! The code will get reviewed. If the review passes, a project-member will merge it onto `master` and `release-*` (see below), and will release new bugfix-versions. + +### Test cases + +We encourage you to write a test case for your pull-request. rsnapshot lacks of a proper testsuite, so please write tests whenever you create a Pull-request touching code at the program. We can verify your changes and intentions easier. + + 1. Create a directory in the testsuite-folder (`t/`) with the desired test-name. And create in this also a subfolder named `conf`. + 2. Copy the skelleton-file from `t/support/skel/testcase` into your testcase-folder and name it like your folder with the **ending `.t.in`**. + 3. Do the same with the conf-file `t/support/skel/testconf`, but copy it into your conf-folder. Give the file the same name and with the **ending `.conf.in`**. + 4. Write your tests and of course test them. + +A few notes on the testsuite: + + - Use the SysWrap-module actively. + - Any file commited in the testsuite-folder ending with `.conf` or `.t` is commited or named wrong. + - Let your files always end with `.in` and execute `autogen.sh` before you run your testsuite. + - Always place your configuration-files into the `conf`-subfolder. + - If you have got multiple tests to check, which are quite similar, use one test-file, and multiple configuration-files located in your test-folder. (Look at the cmd-post_pre-exec testcase). + +## Releases and versions + +### release-branches + +Releases should be done from branches, named for the release version, e.g. `release-1.4`. The first release of that version should be tagged `1.4.0`. Subsequent releases of that version, which should contain no changes other than bugfixes and security fixes, should also be tagged, e.g. `1.4.1`. + +In the end, there should be for every minor release a branch like `release-X.Y`. The sub-releases should only get tagged on their specific branches. + +### release-model in practice + +Here is a model presented for release 1.4.0.

Using rsnapshot, it is possible to take snapshots of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of multiple full backups, while only taking up the space of one full backup plus differences. When coupled with ssh, it is possible to take snapshots of remote filesystems as well.rsnapshot is written in Perl, and depends on rsync. OpenSSH, GNU cp, GNU du, and the BSD logger program are also recommended, but not required. All of these should be present on most Linux systems. rsnapshot is written with the lowest common denominator in mind. It only requires at minimum Perl 5.004 and rsync. As a result of this, it works on pretty much any UNIX-like system you care to throw at it. It has been successfully tested with Perl 5.004 through 5.8.2, on Debian, Redhat, Fedora, Solaris, Mac OS X, FreeBSD, OpenBSD, NetBSD, and IRIX.The latest version of the program and this document can always be found at http://www.rsnapshot.org/.What you will needWhat you will needAt a minimum: perl, rsyncOptionally: ssh, logger, GNU cp, GNU duAdditionally, it will help if you have reasonably good sysadmin skills.Copyright and LicenseCopyright and LicenseThis document, rsnapshot HOWTO, is copyrighted (c) 2005 by Nathan Rosenquist.

These worked very well, but there were a number of things that I wanted to improve upon. I had to write two shell scripts that were customized for my server. If I wanted to change the number of intervals stored, or the parts of the filesystem that were archived, that meant manually editing these shell scripts. If I wanted to install them on a different server with a different configuration, this meant manually editing the scripts for the new server, and hoping the logic and the sequence of operations was correct. Also, I was doing all the backups locally, on a single machine, on a single hard drive (just to protect from dumb user mistakes like deleting files). Never the less, I continued on with this system for a while, and it did work very well.Several months later, the IDE controller on my web server failed horribly (when I typed /sbin/shutdown, it said the command was not found). I was then faced with what was in the back of my mind all along: I had not been making regular remote backups of my server, and the local backups were of no use to me since the entire drive was corrupted. The reason I had only been making sporadic, partial remote backups is that they weren't automatic and effortless. Of course, this was no one's fault but my own, but I got frustrated enough to write a tool that would make automated remote snapshots so easy that I wouldn't ever have to worry about them again. This goal has long been reached, but work on rsnapshot still continues as people submit patches, request features, and ways are found to improve the program.InstallationInstallationThis section will walk you through the installation of rsnapshot, step by step. This is not the only way to do it, but it is a way that works and that is well documented. Feel free to improvise if you know what you're doing.This guide assumes you are installing rsnapshot 1.2.0 for the first time. If you are upgrading from an earlier version, please read the INSTALL file that comes with the source distribution instead.30 second version (for the impatient)30 second version (for the impatient)./configure --sysconfdir=/etc -su -make install -cp /etc/rsnapshot.conf.default /etc/rsnapshot.confThe rest of this section is the long version.Untar the source code packageUntar the source code packagetar xzvf rsnapshot-1.2.0.tar.gzIf you don't have GNU tar, you may have to do this in two steps instead:gunzip rsnapshot-1.2.0.tar.gz -tar xvf rsnapshot-1.2.0.tarChange to the source directoryChange to the source directorycd rsnapshot-1.2.0/Decide where you want to installDecide where you want to installBy default, the installation procedure will install all files under /usr/local. For this tutorial, this will be OK except we will install the config file under /etc.We are assuming that rsync, ssh, logger, and du are all in your search path. If this is not the case, you can specify the path to any of these programs using the typical Autoconf --with-program=/path/to/program syntax. For example, if Perl was in /opt/bin/perl and rsync was in /home/me/bin/rsync, you could run configure like:./configure --with-perl=/opt/bin/perl --with-rsync=/home/me/bin/rsyncRun the configure scriptRun the configure scriptThis will poke and prod your system to figure out where the various external programs that rsnapshot depends on live. It also generates the Makefile that we will use to install the program. The configure script accepts arguments that can be used to tell it where to install the program, and also where to find the supporting programs. For this installation, the only non-default option we want is to put the config file in the /etc directory. To do this, run this command at the shell:./configure --sysconfdir=/etcIf all goes well, you're ready to install the program. If there was a problem, it should be descriptive. Most likely a problem would be the result of something that was required and not found (like rsync or perl). If this happens, you must figure out where the missing program is located on your system, or install it if necessary. If you know where it is but configure couldn't find it, you can specify the path using the --with-program=/path/to/program options described above.Install the programInstall the programIf you've followed these instructions so far, you will have configured rsnapshot to be installed under /usr/local, with the config file in /etc. Under these circumstances, it will be necessary to become root to install the program. Now is the time to do so. You will, of course, need the root password to do this:suThis will prompt you for the root password.Now, to install rsnapshot, run the following command:make installThis will install rsnapshot with all the settings you specified in the ./configure stage. If all goes well, you will have the following files on your system:/usr/local/bin/rsnapshot The rsnapshot program/usr/local/man/man1/rsnapshot.1 Man page/etc/rsnapshot.conf.default The example config fileIf you decide later that you don't want rsnapshot on your system anymore, simply remove the files listed above, or run make uninstall in the same source directory you installed from. Of course, if you installed with different options, the location of these files may be different.ConfigurationConfigurationCreate the config fileCreate the config fileIn the install process, the config file is not created or installed. However, a working example is provided that you can copy. To copy the example config file into the location rsnapshot will be looking for the real config file:cp /etc/rsnapshot.conf.default /etc/rsnapshot.confAs a general rule, you should avoid modifying /etc/rsnapshot.conf.default, simply because it is a working example that you may wish to refer to later. Also, if you perform an upgrade, the rsnapshot.conf.default file will always be upgraded to the latest version, while your real config file will be safe out of harm's way. Please note that if you run make upgrade during an upgrade, your rsnapshot.conf may be modified slightly, and the original will then be saved in rsnapshot.conf.backup in the same directory.Where to go for more infoWhere to go for more infoThe rsnapshot.conf config file is well commented, and much of it should be fairly self-explanatory. For a full reference of all the various options, please consult the rsnapshot man page. Type:man rsnapshotThis will give you the complete documentation. However, it assumes that you already know what you're doing to a certain extent. If you just want to get something up and running, this tutorial is a better place to start. If your system can't find the man page, /usr/local/man probably isn't in your $MANPATH environmental variable. This is beyond the scope of this document, but if it isn't working for you, you can always read the newest man page on the rsnapshot web site at http://www.rsnapshot.org/Modifying the config fileModifying the config fileIn this example, we will be using the /.snapshots/ directory to hold the filesystem snapshots. This is referred to as the “snapshot rootâ€. Feel free to put this anywhere you have lots of free disk space. However, the examples in this document assume you have not changed this parameter, so you will have to substitute this in your commands if you put it somewhere else.Also please note that fields are separated by tabs, not spaces. The reason for this is so it's easier to specify file paths with spaces in them.cmd_cpIf enabled, the cmd_cp parameter should contain the path to the GNU cp program on your filesystem. If you are using Linux, be sure to uncomment this by removing the hash mark (#) in front of it. If you are using BSD, Solaris, IRIX, or most other UNIX variants, you should leave this commented out.What makes GNU cp so special is that unlike the traditional UNIX cp, it has the ability to make recursive “copies†of directories as hard links.If you don't have GNU cp, there is a subroutine in rsnapshot that somewhat approximates this functionality (although it won't support more esoteric files such as device nodes, FIFOs, sockets, etc). This gets followed up by another call to rsync, which transfers the remaining special files, if any. In this way, rsnapshot can support all file types on every platform.The rule of thumb is that if you're on a Linux system, leave cmd_cp enabled. If you aren't on a Linux system, leave cmd_cp disabled. There are reports of GNU cp working on BSD and other non-Linux platforms, but there have also been some cases where problems have been encountered. If you enable cmd_cp on a non-Linux platform, please let the mailing list know how it worked out for you.cmd_rsyncThe cmd_rsync parameter must not be commented out, and it must point to a working version of rsync. If it doesn't, the program just will not work at all.Please note that if you are using IRIX, there is another program named rsync that is different than the “real†rsync most people know of. If you're on an IRIX machine, you should double check this.cmd_sshIf you have ssh installed on your system, you will want to uncomment the cmd_ssh parameter. By enabling ssh, you can take snapshots of any number of remote systems. If you don't have ssh, or plan to only take snapshots of the local filesystem, you may safely leave this commented out.cmd_loggerThe cmd_logger parameter specifies the path to the logger program. logger is a command line interface to syslog. See the logger man page for more details. logger should be a standard part of most UNIX-like systems. It appears to have remained unchanged since about 1993, which is good for cross-platform stability. If you comment out this parameter, it will disable syslog support in rsnapshot. It is recommended that you leave this enabled.cmd_duThe cmd_du parameter specifies the path to the du program. du is a command line tool that reports on disk usage. rsnapshot uses du to generate reports about the actual amount of disk space taken up, which is otherwise difficult to estimate because of all the hard links.If you comment this out, rsnapshot will try to use the version of du it finds in your path, if possible. The GNU version of du is recommended, since it has the best selection of features, and supports the most options. The BSD version also seems to work, although some versions don't support the -h flag. Solaris du does not work at all, because it doesn't support the -c parameter.link_destIf you have rsync version 2.5.7 or later, you may want to enable this. With link_dest enabled, rsnapshot relies on rsync to create recursive hard links, overriding GNU cp in most, but not all, cases. With link_dest enabled, every single file on your system can be backed up in one pass, on any operating system. To get the most out of rsnapshot on non-Linux platforms, link_dest should be enabled. Be advised, however, that if a remote host is unavailable during a backup, rsnapshot will take an extra step and roll back the files from the previous backup. Using GNU cp, this would not be necessary.intervalrsnapshot has no idea how often you want to take snapshots. Everyone's backup scheme may be different. In order to specify how much data to save, you need to tell rsnapshot which “intervals†to keep, and how many of each. An interval, in the context of the rsnapshot config file, is a unit of time measurement. These can actually be named anything (as long as it's alphanumeric, and not a reserved word), but by convention we will call ours hourly and daily. In this example, we want to take a snapshot every four hours, or six times a day (these are the hourly intervals). We also want to keep a second set, which are taken once a day, and stored for a week (or seven days). This happens to be the default, so as you can see the config file reads:interval hourly 6 -interval daily 7It also has some other entries, but you can either ignore them or comment them out for now.Please note that the hourly interval is specified first. This is very important. The first interval line is assumed to be the smallest unit of time, with each additional line getting successively larger. Thus, if you add a yearly interval, it should go at the bottom, and if you add a minutes interval, it should go before hourly. It's also worth noting that the snapshots get “pulled up†from the smallest interval to the largest. In this example, the daily snapshots get pulled from the oldest hourly snapshot, not directly from the main filesystem.backupPlease note that the destination paths specified here are based on the assumption that the --relative flag is being passed to rsync via the rsync_long_args parameter. If you are installing for the first time, this is the default setting. If you upgraded from a previous version, please read the INSTALL file that came with the source distribution for more information.This is the section where you tell rsnapshot what files you actually want to back up. You put a “backup†parameter first, followed by the full path to the directory or network path you're backing up. The third column is the relative path you want to back up to inside the snapshot root. Let's look at an example:backup /etc/ localhost/In this example, backup tells us it's a backup point. /etc/ is the full path to the directory we want to take snapshots of, and localhost/ is a directory inside the snapshot_root we're going to put them in. Using the word localhost as the destination directory is just a convention. You might also choose to use the server's fully qualified domain name instead of localhost. If you are taking snapshots of several machines on one dedicated backup server, it's a good idea to use their various hostnames as directories to keep track of which files came from which server.In addition to full paths on the local filesystem, you can also backup remote systems using rsync over ssh. If you have ssh installed and enabled (via the cmd_ssh parameter), you can specify a path like:backup root@example.com:/etc/ example.com/This behaves fundamentally the same way, but you must take a few extra things into account.•The ssh daemon must be running on example.com•You must have access to the account you specify the remote machine, in this case the root user on example.com.•You must have key-based logins enabled for the root user at example.com, without passphrases. If you wanted to perform backups as another user, you could specify the other user instead of root for the source (i.e. user@domain.com). Please note that allowing remote logins with no passphrase is a security risk that may or may not be acceptable in your situation. Make sure you guard access to the backup server very carefully! For more information on how to set this up, please consult the ssh man page, or a tutorial on using ssh public and private keys. You will find that the key based logins are better in many ways, not just for rsnapshot but for convenience and security in general. Troy Johnson [http://www.jdmz.net/rsnapshot]'s excellent tutorial on using nifty ssh features for secure snapshots which, in case his site ever suffers a mishap, is mirrored here [http://www.rsnapshot.org/howto/using-rsnapshot-and-ssh.html] on this site.•This backup occurs over the network, so it may be slower. Since this uses rsync, this is most noticeable during the first backup. Depending on how much your data changes, subsequent backups should go much, much faster since rsync only sends the differences between files.backup_scriptWith this parameter, the second column is the full path to an executable backup script, and the third column is the local path you want to store it in (just like with the "backup" parameter). For example:backup_script /usr/local/bin/backup_pgsql.sh localhost/postgres/In this example, rsnapshot will run the script /usr/local/bin/backup_pgsql.sh in a temp directory, then sync the results into the localhost/postgres/ directory under the snapshot root. You can find the backup_pgsql.sh example script in the utils/ directory of the source distribution. Feel free to modify it for your system.Your backup script simply needs to dump out the contents of whatever it does into it's current working directory. It can create as many files and/or directories as necessary, but it should not put its files in any pre-determined path. The reason for this is that rsnapshot creates a temp directory, changes to that directory, runs the backup script, and then syncs the contents of the temp directory to the local path you specified in the third column. A typical backup script would be one that archives the contents of a database. It might look like this:#!/bin/sh - -/usr/bin/mysqldump -uroot mydatabase > mydatabase.sql -/bin/chmod 644 mydatabase.sqlThere are several example scripts in the utils/ directory of the rsnapshot source distribution to give you more ideas.Make sure the destination path you specify is unique. The backup script will completely overwrite anything in the destination path, so if you tried to specify the same destination twice, you would be left with only the files from the last script. Fortunately, rsnapshot will try to prevent you from doing this when it reads the config file.Please remember that these backup scripts will be invoked as the user running rsnapshot. In our example, this is root. Make sure your backup scripts are owned by root, and not writable by anyone else. If you fail to do this, anyone with write access to these backup scripts will be able to put commands in them that will be run as the root user. If they are malicious, they could take over your server.Testing your config fileTesting your config fileWhen you have made all your changes, you should verify that the config file is syntactically valid, and that all the supporting programs are where you think they are. To do this, run rsnapshot with the configtest argument:rsnapshot configtestIf all is well, it should say Syntax OK. If there's a problem, it should tell you exactly what it is. Make sure your config file is using tabs and not spaces, etc.The final step to test your configuration is to run rsnapshot in test mode. This will print out a verbose list of the things it will do, without actually doing them. To do a test run, run this command:rsnapshot -t hourlyThis tells rsnapshot to simulate an "hourly" backup. It should print out the commands it will perform when it runs for real. Please note that the test output might be slightly different than the real execution, but only because the test doesn't actually do things that may be checked for later in the program. For example, if the program will create a directory and then later test to see if that directory exists, the test run might claim that it would create the directory twice, since it didn't actually get created during the test. This should be the only type of difference you will see while running a test.AutomationAutomationNow that you have your config file set up, it's time to set up rsnapshot to be run from cron. As the root user, edit root's crontab by typing:crontab -eYou could alternately keep a crontab file that you load in, but the concepts are the same. You want to enter the following information into root's crontab: -0 */4 * * * /usr/local/bin/rsnapshot hourly -30 23 * * * /usr/local/bin/rsnapshot daily -It is usually a good idea to schedule the larger intervals to run a bit before the lower ones. For example, in the crontab above, notice that daily runs 30 minutes before hourly. This helps prevent race conditions where the daily would try to run before the hourly job had finished. This same strategy should be extended so that a weekly entry would run before the daily and so on. -How it worksHow it worksWe have a snapshot root under which all backups are stored. By default, this is the directory /.snapshots/. Within this directory, other directories are created for the various intervals that have been defined. In the beginning it will be empty, but once rsnapshot has been running for a week, it should look something like this: -[root@localhost]# ls -l /.snapshots/ -drwxr-xr-x 7 root root 4096 Dec 28 00:00 daily.0 -drwxr-xr-x 7 root root 4096 Dec 27 00:00 daily.1 -drwxr-xr-x 7 root root 4096 Dec 26 00:00 daily.2 -drwxr-xr-x 7 root root 4096 Dec 25 00:00 daily.3 -drwxr-xr-x 7 root root 4096 Dec 24 00:00 daily.4 -drwxr-xr-x 7 root root 4096 Dec 23 00:00 daily.5 -drwxr-xr-x 7 root root 4096 Dec 22 00:00 daily.6 -drwxr-xr-x 7 root root 4096 Dec 29 00:00 hourly.0 -drwxr-xr-x 7 root root 4096 Dec 28 20:00 hourly.1 -drwxr-xr-x 7 root root 4096 Dec 28 16:00 hourly.2 -drwxr-xr-x 7 root root 4096 Dec 28 12:00 hourly.3 -drwxr-xr-x 7 root root 4096 Dec 28 08:00 hourly.4 -drwxr-xr-x 7 root root 4096 Dec 28 04:00 hourly.5 -Inside each of these directories is a “full†backup of that point in time. The destination directory paths you specified under the backup and backup_script parameters get stuck directly under these directories. In the example:backup /etc/ localhost/The /etc/ directory will initially get backed up into /.snapshots/hourly.0/localhost/etc/Each subsequent time rsnapshot is run with the hourly command, it will rotate the hourly.X directories, and then “copy†the contents of the hourly.0 directory (using hard links) into hourly.1.When rsnapshot daily is run, it will rotate all the daily.X directories, then copy the contents of hourly.5 into daily.0.hourly.0 will always contain the most recent snapshot, and daily.6 will always contain a snapshot from a week ago. Unless the files change between snapshots, the “full†backups are really just multiple hard links to the same files. Thus, if your /etc/passwd file doesn't change in a week, hourly.0/localhost/etc/passwd and daily.6/localhost/etc/passwd will literally be the same exact file. This is how rsnapshot can be so efficient on space. If the file changes at any point, the next backup will unlink the hard link in hourly.0, and replace it with a brand new file. This will now take double the disk space it did before, but it is still considerably less than it would be to have full unique copies of this file 13 times over.Remember that if you are using different intervals than the ones in this example, the first interval listed is the one that gets updates directly from the main filesystem. All subsequently listed intervals pull from the previous intervals. For example, if you had weekly, monthly, and yearly intervals defined (in that order), the weekly ones would get updated directly from the filesystem, the monthly ones would get updated from weekly, and the yearly ones would get updated from monthly.Restoring backupsRestoring backupsWhen rsnapshot is first run, it will create the snapshot_root directory (/.snapshots/ by default). It assigns this directory the permissions 700, and for good reason. The snapshot root will probably contain files owned by all sorts of users on your system. If any of these files are writeable (and of course some of them will be), the users will still have write access to their files. Thus, if they can see the snapshots directly, they can modify them, and the integrity of the snapshots can not be guaranteed.For example, if a user had write permission to the backups and accidentally ran rm -rf /, they would delete all their files in their home directory and all the files they owned in the backups!root onlyroot onlyThe simplest, but least flexible solution, is to simply deny non-root users access to the snapshot root altogether. The root user will still have access of course, and as with all other aspects of system administration, must be trusted not to go messing with things too much. However, by simply denying access to everyone, the root user will be the only one who can pull backups. This may or may not be desirable, depending on your situation. For a small setup or a single-user machine, this may be all you need.All usersAll usersIf users need to be able to pull their own backups, you will need to do a little extra work up front (but probably less work in the long run). The best way to do this seems to be creating a container directory for the snapshot root with 700 permissions, giving the snapshot root directory 755 permissions, and mounting the snapshot root for the users read-only. This can be done over NFS and Samba, to name two possibilities. Let's explore how to do this using NFS on a single machine:Set the snapshot_root variable in /etc/rsnapshot.conf equal to /.private/.snapshots/snapshot_root /.private/.snapshots/Create the container directory:mkdir /.private/Create the real snapshot root:mkdir /.private/.snapshots/Create the read-only snapshot root mount point:mkdir /.snapshots/Set the proper permissions on these new directories:chmod 0700 /.private/ -chmod 0755 /.private/.snapshots/ -chmod 0755 /.snapshots/In /etc/exports, add /.private/.snapshots/ as a read only NFS export:/.private/.snapshots/ 127.0.0.1(ro,no_root_squash)In /etc/fstab, mount /.private/.snapshots/ read-only under /.snapshots/localhost:/.private/.snapshots/ /.snapshots/ nfs ro 0 0You should now restart your NFS daemon.Now mount the read-only snapshot root:mount /.snapshots/To test this, go into the /.snapshots/ directory as root. It is set to read-only, so even root shouldn't be able to write to it. As root, try:touch /.snapshots/testfileThis should fail, citing insufficient permissions. This is what you want. It means that your users won't be able to mess with the snapshots either.Now, all your users have to do to recover old files is go into the /.snapshots directory, select the interval they want, and browse through the filesystem until they find the files they are looking for. They can't modify anything in here because NFS will prevent them, but they can copy anything that they had read permission for in the first place. All the regular filesystem permissions are still at work, but the read-only NFS mount prevents any writes from happening.Please note that some NFS configurations may prevent you from accessing files that are owned by root and set to only be readable by root. In this situation, you may wish to pull backups for root from the "real" snapshot root, and let non-privileged users pull from the read-only NFS mount.ConclusionConclusionIf you followed the instructions in this document, you should now have rsnapshot installed and set up to perform automatic backups of your system. If it's not working, go back and trace your steps back to see if you can isolate the problem.The amount of disk space taken up will be equal to one full backup, plus an additional copy of every file that is changed. There is also a slight disk space overhead with creating multiple hard links, but it's not very much. On my system, adding a second, completely identical 3 Gigabyte interval alongside the original one only added about 15 Megabytes.You can use the du option to rsnapshot to generate disk usage reports. To see the sum total of all space used, try:rsnapshot duIf you were storing backups under localhost/home/ and wanted to see how much this subdirectory takes up throughout all your backups, try this instead:rsnapshot du localhost/home/The latest version of this document and the rsnapshot program can always be found at http://www.rsnapshot.org/More resourcesMore resourcesWeb sitesMike Rubel's original shell scripts, upon which this project is based - http://www.mikerubel.org/computers/rsync_snapshots/ - Perl - http://www.perl.org/ - GNU cp and du (coreutils package) - http://www.gnu.org/software/coreutils/ - rsync - http://rsync.samba.org/ - OpenSSH - http://www.openssh.org/ - rsnapshot - http://www.rsnapshot.org/ - diff -Nru rsnapshot-1.4.4/docs/docbook/rsnapshot-HOWTO.en.info rsnapshot-1.4.5/docs/docbook/rsnapshot-HOWTO.en.info --- rsnapshot-1.4.4/docs/docbook/rsnapshot-HOWTO.en.info 2019-12-09 04:28:11.000000000 +0000 +++ rsnapshot-1.4.5/docs/docbook/rsnapshot-HOWTO.en.info 1970-01-01 00:00:00.000000000 +0000 @@ -1,998 +0,0 @@ -This is rsnapshot-HOWTO.en.info, produced by makeinfo version 4.8 from -rsnapshot-HOWTO.en.texi. - -START-INFO-DIR-ENTRY -* rsnapshot HOWTO: . ??? -END-INFO-DIR-ENTRY - - -File: rsnapshot-HOWTO.en.info, Node: Top, Next: Introduction, Up: (dir) - -rsnapshot HOWTO -*************** - -* Menu: - -* Introduction:: -* Motivation:: -* Installation:: -* Configuration:: -* Automation:: -* How it works:: -* Restoring backups:: -* Conclusion:: -* More resources:: - ---- The Detailed Node Listing --- - -Introduction - -* What you will need:: -* Copyright and License:: -* Disclaimer:: -* Feedback:: - -Installation - -* 30 second version [for the impatient]:: -* Untar the source code package:: -* Change to the source directory:: -* Decide where you want to install:: -* Run the configure script:: -* Install the program:: - -Configuration - -* Create the config file:: -* Where to go for more info:: -* Modifying the config file:: -* Testing your config file:: - -Restoring backups - -* root only:: -* All users:: - - -File: rsnapshot-HOWTO.en.info, Node: Introduction, Next: Motivation, Prev: Top, Up: Top - -1 Introduction -************** - -rsnapshot is a filesystem backup utility based on rsync. Using -rsnapshot, it is possible to take snapshots of your filesystems at -different points in time. Using hard links, rsnapshot creates the -illusion of multiple full backups, while only taking up the space of -one full backup plus differences. When coupled with ssh, it is possible -to take snapshots of remote filesystems as well. - - rsnapshot is written in Perl, and depends on rsync. OpenSSH, GNU cp, -GNU du, and the BSD logger program are also recommended, but not -required. All of these should be present on most Linux systems. -rsnapshot is written with the lowest common denominator in mind. It -only requires at minimum Perl 5.004 and rsync. As a result of this, it -works on pretty much any UNIX-like system you care to throw at it. It -has been successfully tested with Perl 5.004 through 5.8.2, on Debian, -Redhat, Fedora, Solaris, Mac OS X, FreeBSD, OpenBSD, NetBSD, and IRIX. - - The latest version of the program and this document can always be -found at http://www.rsnapshot.org/ (http://www.rsnapshot.org/). - -* Menu: - -* What you will need:: -* Copyright and License:: -* Disclaimer:: -* Feedback:: - - -File: rsnapshot-HOWTO.en.info, Node: What you will need, Next: Copyright and License, Up: Introduction - -1.1 What you will need -====================== - -At a minimum: perl, rsync - - Optionally: ssh, logger, GNU cp, GNU du - - Additionally, it will help if you have reasonably good sysadmin -skills. - - -File: rsnapshot-HOWTO.en.info, Node: Copyright and License, Next: Disclaimer, Prev: What you will need, Up: Introduction - -1.2 Copyright and License -========================= - -This document, rsnapshot HOWTO, is copyrighted (c) 2005 by Nathan -Rosenquist.

These worked very well, but there were a number of things -that I wanted to improve upon. I had to write two shell scripts that -were customized for my server. If I wanted to change the number of -intervals stored, or the parts of the filesystem that were archived, -that meant manually editing these shell scripts. If I wanted to install -them on a different server with a different configuration, this meant -manually editing the scripts for the new server, and hoping the logic -and the sequence of operations was correct. Also, I was doing all the -backups locally, on a single machine, on a single hard drive (just to -protect from dumb user mistakes like deleting files). Never the less, I -continued on with this system for a while, and it did work very well. - - Several months later, the IDE controller on my web server failed -horribly (when I typed `/sbin/shutdown', it said the command was not -found). I was then faced with what was in the back of my mind all -along: I had not been making regular remote backups of my server, and -the local backups were of no use to me since the entire drive was -corrupted. The reason I had only been making sporadic, partial remote -backups is that they weren't automatic and effortless. Of course, this -was no one's fault but my own, but I got frustrated enough to write a -tool that would make automated remote snapshots so easy that I wouldn't -ever have to worry about them again. This goal has long been reached, -but work on rsnapshot still continues as people submit patches, request -features, and ways are found to improve the program. - - -File: rsnapshot-HOWTO.en.info, Node: Installation, Next: Configuration, Prev: Motivation, Up: Top - -3 Installation -************** - -This section will walk you through the installation of rsnapshot, step -by step.

For this tutorial, this will be OK except we will install -the config file under `/etc'. - - We are assuming that `rsync', `ssh', `logger', and `du' are all in -your search path. If this is not the case, you can specify the path to -any of these programs using the typical Autoconf -`--with-program=/path/to/program' syntax. For example, if Perl was in -`/opt/bin/perl' and rsync was in `/home/me/bin/rsync', you could run -configure like: - - ./configure --with-perl=/opt/bin/perl --with-rsync=/home/me/bin/rsync - - -File: rsnapshot-HOWTO.en.info, Node: Run the configure script, Next: Install the program, Prev: Decide where you want to install, Up: Installation - -3.5 Run the configure script -============================ - -This will poke and prod your system to figure out where the various -external programs that rsnapshot depends on live. It also generates the -Makefile that we will use to install the program. The configure script -accepts arguments that can be used to tell it where to install the -program, and also where to find the supporting programs. For this -installation, the only non-default option we want is to put the config -file in the `/etc' directory. To do this, run this command at the shell: - - ./configure --sysconfdir=/etc - - If all goes well, you're ready to install the program. If there was -a problem, it should be descriptive. Most likely a problem would be the -result of something that was required and not found (like rsync or -perl). If this happens, you must figure out where the missing program -is located on your system, or install it if necessary. If you know -where it is but configure couldn't find it, you can specify the path -using the `--with-program=/path/to/program' options described above. - - -File: rsnapshot-HOWTO.en.info, Node: Install the program, Prev: Run the configure script, Up: Installation - -3.6 Install the program -======================= - -If you've followed these instructions so far, you will have configured -rsnapshot to be installed under `/usr/local', with the config file in -`/etc'.

You will, of course, -need the root password to do this: - - su - - This will prompt you for the root password. - - Now, to install rsnapshot, run the following command: - - make install - - This will install rsnapshot with all the settings you specified in -the ./configure stage. If all goes well, you will have the following -files on your system: - - `/usr/local/bin/rsnapshot' The rsnapshot program - - `/usr/local/man/man1/rsnapshot.1' Man page - - `/etc/rsnapshot.conf.default' The example config file - - If you decide later that you don't want rsnapshot on your system -anymore, simply remove the files listed above, or run `make uninstall' -in the same source directory you installed from.

The GNU version of `du' is -recommended, since it has the best selection of features, and supports -the most options.

To get the most out of -rsnapshot on non-Linux platforms, link_dest should be enabled. Be -advised, however, that if a remote host is unavailable during a backup, -rsnapshot will take an extra step and roll back the files from the -previous backup.

Everyone's -backup scheme may be different. In order to specify how much data to -save, you need to tell rsnapshot which intervals to keep, and how many -of each. An interval, in the context of the rsnapshot config file, is a -unit of time measurement. These can actually be named anything (as long -as it's alphanumeric, and not a reserved word), but by convention we -will call ours hourly and daily. In this example, we want to take a -snapshot every four hours, or six times a day (these are the hourly -intervals). We also want to keep a second set, which are taken once a -day, and stored for a week (or seven days). This happens to be the -default, so as you can see the config file reads: - - interval hourly 6 - interval daily 7 - - It also has some other entries, but you can either ignore them or -comment them out for now. - - Please note that the hourly interval is specified first. This is -very important. The first interval line is assumed to be the smallest -unit of time, with each additional line getting successively larger. -Thus, if you add a yearly interval, it should go at the bottom, and if -you add a minutes interval, it should go before hourly. It's also worth -noting that the snapshots get pulled up from the smallest interval to -the largest. In this example, the daily snapshots get pulled from the -oldest hourly snapshot, not directly from the main filesystem. - - -File: rsnapshot-HOWTO.en.info, Node: backup, Next: backup_script, Prev: interval, Up: Modifying the config file - -4.3.8 backup ------------- - -Please note that the destination paths specified here are based on the -assumption that the -relative flag is being passed to `rsync' via the -rsync_long_args parameter. If you are installing for the first time, -this is the default setting. If you upgraded from a previous version, -please read the `INSTALL' file that came with the source distribution -for more information. - - This is the section where you tell rsnapshot what files you actually -want to back up. You put a backup parameter first, followed by the full -path to the directory or network path you're backing up. The third -column is the relative path you want to back up to inside the snapshot -root. Let's look at an example: - - backup /etc/ localhost/ - - In this example, backup tells us it's a backup point. `/etc/' is the -full path to the directory we want to take snapshots of, and -`localhost/' is a directory inside the snapshot_root we're going to put -them in. Using the word localhost as the destination directory is just -a convention. You might also choose to use the server's fully qualified -domain name instead of localhost. If you are taking snapshots of -several machines on one dedicated backup server, it's a good idea to -use their various hostnames as directories to keep track of which files -came from which server. - - In addition to full paths on the local filesystem, you can also -backup remote systems using `rsync' over `ssh'. If you have `ssh' -installed and enabled (via the cmd_ssh parameter), you can specify a -path like: - - backup root@example.com:/etc/ example.com/ - - This behaves fundamentally the same way, but you must take a few -extra things into account. - - * The ssh daemon must be running on example.com - - * You must have access to the account you specify the remote - machine, in this case the root user on example.com. - - * You must have key-based logins enabled for the root user at - example.com, without passphrases. If you wanted to perform backups - as another user, you could specify the other user instead of root - for the source (i.e. user@domain.com). Please note that allowing - remote logins with no passphrase is a security risk that may or - may not be acceptable in your situation. Make sure you guard - access to the backup server very carefully! For more information - on how to set this up, please consult the ssh man page, or a - tutorial on using ssh public and private keys. You will find that - the key based logins are better in many ways, not just for - rsnapshot but for convenience and security in general. Troy - Johnson (http://www.jdmz.net/rsnapshot)'s excellent tutorial on - using nifty ssh features for secure snapshots which, in case his - site ever suffers a mishap, is mirrored here - (http://www.rsnapshot.org/howto/using-rsnapshot-and-ssh.html) on - this site. - - * This backup occurs over the network, so it may be slower. Since - this uses `rsync', this is most noticeable during the first - backup. Depending on how much your data changes, subsequent - backups should go much, much faster since rsync only sends the - differences between files. - - -File: rsnapshot-HOWTO.en.info, Node: backup_script, Prev: backup, Up: Modifying the config file - -4.3.9 backup_script -------------------- - -With this parameter, the second column is the full path to an -executable backup script, and the third column is the local path you -want to store it in (just like with the "backup" parameter). For -example: - - backup_script /usr/local/bin/backup_pgsql.sh localhost/postgres/ - - In this example, rsnapshot will run the script -`/usr/local/bin/backup_pgsql.sh' in a temp directory, then sync the -results into the `localhost/postgres/' directory under the snapshot -root. You can find the backup_pgsql.sh example script in the `utils/' -directory of the source distribution. Feel free to modify it for your -system. - - Your backup script simply needs to dump out the contents of whatever -it does into it's current working directory. It can create as many -files and/or directories as necessary, but it should not put its files -in any pre-determined path. The reason for this is that rsnapshot -creates a temp directory, changes to that directory, runs the backup -script, and then syncs the contents of the temp directory to the local -path you specified in the third column. A typical backup script would -be one that archives the contents of a database. It might look like -this: - - #!/bin/sh - - /usr/bin/mysqldump -uroot mydatabase > mydatabase.sql - /bin/chmod 644 mydatabase.sql - - There are several example scripts in the `utils/' directory of the -rsnapshot source distribution to give you more ideas. - - Make sure the destination path you specify is unique. The backup -script will completely overwrite anything in the destination path, so -if you tried to specify the same destination twice, you would be left -with only the files from the last script. Fortunately, rsnapshot will -try to prevent you from doing this when it reads the config file. - - Please remember that these backup scripts will be invoked as the -user running rsnapshot. In our example, this is root. Make sure your -backup scripts are owned by root, and not writable by anyone else. If -you fail to do this, anyone with write access to these backup scripts -will be able to put commands in them that will be run as the root user. -If they are malicious, they could take over your server. - - -File: rsnapshot-HOWTO.en.info, Node: Testing your config file, Prev: Modifying the config file, Up: Configuration - -4.4 Testing your config file -============================ - -When you have made all your changes, you should verify that the config -file is syntactically valid, and that all the supporting programs are -where you think they are. To do this, run rsnapshot with the configtest -argument: - - rsnapshot configtest - - If all is well, it should say `Syntax OK'. If there's a problem, it -should tell you exactly what it is. Make sure your config file is using -tabs and not spaces, etc. - - The final step to test your configuration is to run rsnapshot in -test mode. This will print out a verbose list of the things it will do, -without actually doing them. To do a test run, run this command: - - rsnapshot -t hourly - - This tells rsnapshot to simulate an "hourly" backup. It should print -out the commands it will perform when it runs for real. Please note -that the test output might be slightly different than the real -execution, but only because the test doesn't actually do things that -may be checked for later in the program. For example, if the program -will create a directory and then later test to see if that directory -exists, the test run might claim that it would create the directory -twice, since it didn't actually get created during the test. This -should be the only type of difference you will see while running a test. - - -File: rsnapshot-HOWTO.en.info, Node: Automation, Next: How it works, Prev: Configuration, Up: Top - -5 Automation -************ - -Now that you have your config file set up, it's time to set up -rsnapshot to be run from cron. As the root user, edit root's crontab by -typing: - - crontab -e - - You could alternately keep a crontab file that you load in, but the -concepts are the same. You want to enter the following information into -root's crontab: - - - 0 */4 * * * /usr/local/bin/rsnapshot hourly - 30 23 * * * /usr/local/bin/rsnapshot daily - - It is usually a good idea to schedule the larger intervals to run a -bit before the lower ones. For example, in the crontab above, notice -that daily runs 30 minutes before hourly. This helps prevent race -conditions where the daily would try to run before the hourly job had -finished. This same strategy should be extended so that a weekly entry -would run before the daily and so on. - - -File: rsnapshot-HOWTO.en.info, Node: How it works, Next: Restoring backups, Prev: Automation, Up: Top - -6 How it works -************** - -We have a snapshot root under which all backups are stored. By default, -this is the directory `/.snapshots/'. Within this directory, other -directories are created for the various intervals that have been -defined. In the beginning it will be empty, but once rsnapshot has been -running for a week, it should look something like this: - - - [root@localhost]# ls -l /.snapshots/ - drwxr-xr-x 7 root root 4096 Dec 28 00:00 daily.0 - drwxr-xr-x 7 root root 4096 Dec 27 00:00 daily.1 - drwxr-xr-x 7 root root 4096 Dec 26 00:00 daily.2 - drwxr-xr-x 7 root root 4096 Dec 25 00:00 daily.3 - drwxr-xr-x 7 root root 4096 Dec 24 00:00 daily.4 - drwxr-xr-x 7 root root 4096 Dec 23 00:00 daily.5 - drwxr-xr-x 7 root root 4096 Dec 22 00:00 daily.6 - drwxr-xr-x 7 root root 4096 Dec 29 00:00 hourly.0 - drwxr-xr-x 7 root root 4096 Dec 28 20:00 hourly.1 - drwxr-xr-x 7 root root 4096 Dec 28 16:00 hourly.2 - drwxr-xr-x 7 root root 4096 Dec 28 12:00 hourly.3 - drwxr-xr-x 7 root root 4096 Dec 28 08:00 hourly.4 - drwxr-xr-x 7 root root 4096 Dec 28 04:00 hourly.5 - - Inside each of these directories is a full backup of that point in -time. The destination directory paths you specified under the backup -and backup_script parameters get stuck directly under these -directories. In the example: - - backup /etc/ localhost/ - - The `/etc/' directory will initially get backed up into -`/.snapshots/hourly.0/localhost/etc/' - - Each subsequent time rsnapshot is run with the hourly command, it -will rotate the `hourly.X' directories, and then copy the contents of -the `hourly.0' directory (using hard links) into `hourly.1'. - - When `rsnapshot daily' is run, it will rotate all the `daily.X' -directories, then copy the contents of `hourly.5' into `daily.0'. - - `hourly.0' will always contain the most recent snapshot, and -`daily.6' will always contain a snapshot from a week ago. Unless the -files change between snapshots, the full backups are really just -multiple hard links to the same files. Thus, if your `/etc/passwd' file -doesn't change in a week, `hourly.0/localhost/etc/passwd' and -`daily.6/localhost/etc/passwd' will literally be the same exact file. -This is how rsnapshot can be so efficient on space. If the file changes -at any point, the next backup will unlink the hard link in `hourly.0', -and replace it with a brand new file. This will now take double the -disk space it did before, but it is still considerably less than it -would be to have full unique copies of this file 13 times over. - - Remember that if you are using different intervals than the ones in -this example, the first interval listed is the one that gets updates -directly from the main filesystem. All subsequently listed intervals -pull from the previous intervals. For example, if you had weekly, -monthly, and yearly intervals defined (in that order), the weekly ones -would get updated directly from the filesystem, the monthly ones would -get updated from weekly, and the yearly ones would get updated from -monthly. - - -File: rsnapshot-HOWTO.en.info, Node: Restoring backups, Next: Conclusion, Prev: How it works, Up: Top - -7 Restoring backups -******************* - -When rsnapshot is first run, it will create the snapshot_root directory -(`/.snapshots/' by default). It assigns this directory the permissions -700, and for good reason. The snapshot root will probably contain files -owned by all sorts of users on your system. If any of these files are -writeable (and of course some of them will be), the users will still -have write access to their files. Thus, if they can see the snapshots -directly, they can modify them, and the integrity of the snapshots can -not be guaranteed. - - For example, if a user had write permission to the backups and -accidentally ran `rm -rf /', they would delete all their files in their -home directory and all the files they owned in the backups! - -* Menu: - -* root only:: -* All users:: - - -File: rsnapshot-HOWTO.en.info, Node: root only, Next: All users, Up: Restoring backups - -7.1 root only -============= - -The simplest, but least flexible solution, is to simply deny non-root -users access to the snapshot root altogether. The root user will still -have access of course, and as with all other aspects of system -administration, must be trusted not to go messing with things too much. -However, by simply denying access to everyone, the root user will be -the only one who can pull backups. This may or may not be desirable, -depending on your situation. For a small setup or a single-user -machine, this may be all you need. - - -File: rsnapshot-HOWTO.en.info, Node: All users, Prev: root only, Up: Restoring backups - -7.2 All users -============= - -If users need to be able to pull their own backups, you will need to do -a little extra work up front (but probably less work in the long run). -The best way to do this seems to be creating a container directory for -the snapshot root with 700 permissions, giving the snapshot root -directory 755 permissions, and mounting the snapshot root for the users -read-only. This can be done over NFS and Samba, to name two -possibilities. Let's explore how to do this using NFS on a single -machine: - - Set the snapshot_root variable in `/etc/rsnapshot.conf' equal to -`/.private/.snapshots/' - - snapshot_root /.private/.snapshots/ - - Create the container directory: - - mkdir /.private/ - - Create the real snapshot root: - - mkdir /.private/.snapshots/ - - Create the read-only snapshot root mount point: - - mkdir /.snapshots/ - - Set the proper permissions on these new directories: - - chmod 0700 /.private/ - chmod 0755 /.private/.snapshots/ - chmod 0755 /.snapshots/ - - In `/etc/exports', add `/.private/.snapshots/' as a read only NFS -export: - - /.private/.snapshots/ 127.0.0.1(ro,no_root_squash) - - In `/etc/fstab', mount `/.private/.snapshots/' read-only under -`/.snapshots/' - - localhost:/.private/.snapshots/ /.snapshots/ nfs ro 0 0 - - You should now restart your NFS daemon. - - Now mount the read-only snapshot root: - - mount /.snapshots/ - - To test this, go into the /.snapshots/ directory as root. It is set -to read-only, so even root shouldn't be able to write to it. As root, -try: - - touch /.snapshots/testfile - - This should fail, citing insufficient permissions. This is what you -want. It means that your users won't be able to mess with the snapshots -either. - - Now, all your users have to do to recover old files is go into the -/.snapshots directory, select the interval they want, and browse -through the filesystem until they find the files they are looking for. -They can't modify anything in here because NFS will prevent them, but -they can copy anything that they had read permission for in the first -place. All the regular filesystem permissions are still at work, but -the read-only NFS mount prevents any writes from happening. - - Please note that some NFS configurations may prevent you from -accessing files that are owned by root and set to only be readable by -root. In this situation, you may wish to pull backups for root from the -"real" snapshot root, and let non-privileged users pull from the -read-only NFS mount. - - -File: rsnapshot-HOWTO.en.info, Node: Conclusion, Next: More resources, Prev: Restoring backups, Up: Top - -8 Conclusion -************ - -If you followed the instructions in this document, you should now have -rsnapshot installed and set up to perform automatic backups of your -system.

- rsnapshot is a filesystem backup utility based on rsync. Using rsnapshot, it is possible to take snapshots - of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of - multiple full backups, while only taking up the space of one full backup plus differences. When coupled - with ssh, it is possible to take snapshots of remote filesystems as well. This document is a tutorial in - the installation and configuration of rsnapshot. -

Introduction

rsnapshot is a filesystem backup utility based on rsync. Using rsnapshot, it is possible to take snapshots of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of multiple full backups, while only taking up the space of one full backup plus differences. When coupled with ssh, it is possible to take snapshots of remote filesystems as well.

rsnapshot is written in Perl, and depends on rsync. OpenSSH, GNU cp, GNU du, and the BSD logger program are also recommended, but not required. All of these should be present on most Linux systems. rsnapshot is written with the lowest common denominator in mind. It only requires at minimum Perl 5.004 and rsync. As a result of this, it works on pretty much any UNIX-like system you care to throw at it. It has been successfully tested with Perl 5.004 through 5.8.2, on Debian, Redhat, Fedora, Solaris, Mac OS X, FreeBSD, OpenBSD, NetBSD, and IRIX.

The latest version of the program and this document can always be found at http://www.rsnapshot.org/.

What you will need

At a minimum: perl, rsync

Optionally: ssh, logger, GNU cp, GNU du

Additionally, it will help if you have reasonably good sysadmin skills.

Motivation

I originally used Mike Rubel's shell scripts to do rsync snapshots a while back. These worked very well, but there were a number of things that I wanted to improve upon. I had to write two shell scripts that were customized for my server. If I wanted to change the number of intervals stored, or the parts of the filesystem that were archived, that meant manually editing these shell scripts. If I wanted to install them on a different server with a different configuration, this meant manually editing the scripts for the new server, and hoping the logic and the sequence of operations was correct. Also, I was doing all the backups locally, on a single machine, on a single hard drive (just to protect from dumb user mistakes like deleting files). Never the less, I continued on with this system for a while, and it did work very well.

Several months later, the IDE controller on my web server failed horribly (when I typed /sbin/shutdown, it said the command was not found). I was then faced with what was in the back of my mind all along: I had not been making regular remote backups of my server, and the local backups were of no use to me since the entire drive was corrupted. The reason I had only been making sporadic, partial remote backups is that they weren't automatic and effortless. Of course, this was no one's fault but my own, but I got frustrated enough to write a tool that would make automated remote snapshots so easy that I wouldn't ever have to worry about them again. This goal has long been reached, but work on rsnapshot still continues as people submit patches, request features, and ways are found to improve the program.

Installation

This section will walk you through the installation of rsnapshot, step by step. This is not the only way to do it, but it is a way that works and that is well documented. Feel free to improvise if you know what you're doing.

This guide assumes you are installing rsnapshot 1.2.0 for the first time. If you are upgrading from an earlier version, please read the INSTALL file that comes with the source distribution instead.

30 second version (for the impatient)

./configure --sysconfdir=/etc
-su
-make install
-cp /etc/rsnapshot.conf.default /etc/rsnapshot.conf

The rest of this section is the long version.

Untar the source code package

tar xzvf rsnapshot-1.2.0.tar.gz

If you don't have GNU tar, you may have to do this in two steps instead:

gunzip rsnapshot-1.2.0.tar.gz
-tar xvf rsnapshot-1.2.0.tar

Change to the source directory

cd rsnapshot-1.2.0/

Decide where you want to install

By default, the installation procedure will install all files under /usr/local. For this tutorial, this will be OK except we will install the config file under /etc.

We are assuming that rsync, ssh, logger, and du are all in your search path. If this is not the case, you can specify the path to any of these programs using the typical Autoconf --with-program=/path/to/program syntax. For example, if Perl was in /opt/bin/perl and rsync was in /home/me/bin/rsync, you could run configure like:

./configure --with-perl=/opt/bin/perl --with-rsync=/home/me/bin/rsync

Run the configure script

This will poke and prod your system to figure out where the various external programs that rsnapshot depends on live. It also generates the Makefile that we will use to install the program. The configure script accepts arguments that can be used to tell it where to install the program, and also where to find the supporting programs. For this installation, the only non-default option we want is to put the config file in the /etc directory. To do this, run this command at the shell:

./configure --sysconfdir=/etc

If all goes well, you're ready to install the program. If there was a problem, it should be descriptive. Most likely a problem would be the result of something that was required and not found (like rsync or perl). If this happens, you must figure out where the missing program is located on your system, or install it if necessary. If you know where it is but configure couldn't find it, you can specify the path using the --with-program=/path/to/program options described above.

Install the program

If you've followed these instructions so far, you will have configured rsnapshot to be installed under /usr/local, with the config file in /etc. Under these circumstances, it will be necessary to become root to install the program. Now is the time to do so. You will, of course, need the root password to do this:

su

This will prompt you for the root password.

Now, to install rsnapshot, run the following command:

make install

This will install rsnapshot with all the settings you specified in the ./configure stage. If all goes well, you will have the following files on your system:

/usr/local/bin/rsnapshot The rsnapshot program

/usr/local/man/man1/rsnapshot.1 Man page

/etc/rsnapshot.conf.default The example config file

If you decide later that you don't want rsnapshot on your system anymore, simply remove the files listed above, or run make uninstall in the same source directory you installed from. Of course, if you installed with different options, the location of these files may be different.

Configuration

Create the config file

In the install process, the config file is not created or installed. However, a working example is provided that you can copy. To copy the example config file into the location rsnapshot will be looking for the real config file:

cp /etc/rsnapshot.conf.default /etc/rsnapshot.conf

As a general rule, you should avoid modifying /etc/rsnapshot.conf.default, simply because it is a working example that you may wish to refer to later. Also, if you perform an upgrade, the rsnapshot.conf.default file will always be upgraded to the latest version, while your real config file will be safe out of harm's way. Please note that if you run make upgrade during an upgrade, your rsnapshot.conf may be modified slightly, and the original will then be saved in rsnapshot.conf.backup in the same directory.

Where to go for more info

The rsnapshot.conf config file is well commented, and much of it should be fairly self-explanatory. For a full reference of all the various options, please consult the rsnapshot man page. Type:

man rsnapshot

This will give you the complete documentation. However, it assumes that you already know what you're doing to a certain extent. If you just want to get something up and running, this tutorial is a better place to start. If your system can't find the man page, /usr/local/man probably isn't in your $MANPATH environmental variable. This is beyond the scope of this document, but if it isn't working for you, you can always read the newest man page on the rsnapshot web site at http://www.rsnapshot.org/

Modifying the config file

In this example, we will be using the /.snapshots/ directory to hold the filesystem snapshots. This is referred to as the “snapshot rootâ€. Feel free to put this anywhere you have lots of free disk space. However, the examples in this document assume you have not changed this parameter, so you will have to substitute this in your commands if you put it somewhere else.

Also please note that fields are separated by tabs, not spaces. The reason for this is so it's easier to specify file paths with spaces in them.

cmd_cp

If enabled, the cmd_cp parameter should contain the path to the GNU cp program on your filesystem. If you are using Linux, be sure to uncomment this by removing the hash mark (#) in front of it. If you are using BSD, Solaris, IRIX, or most other UNIX variants, you should leave this commented out.

What makes GNU cp so special is that unlike the traditional UNIX cp, it has the ability to make recursive “copies†of directories as hard links.

If you don't have GNU cp, there is a subroutine in rsnapshot that somewhat approximates this functionality (although it won't support more esoteric files such as device nodes, FIFOs, sockets, etc). This gets followed up by another call to rsync, which transfers the remaining special files, if any. In this way, rsnapshot can support all file types on every platform.

The rule of thumb is that if you're on a Linux system, leave cmd_cp enabled. If you aren't on a Linux system, leave cmd_cp disabled. There are reports of GNU cp working on BSD and other non-Linux platforms, but there have also been some cases where problems have been encountered. If you enable cmd_cp on a non-Linux platform, please let the mailing list know how it worked out for you.

cmd_rsync

The cmd_rsync parameter must not be commented out, and it must point to a working version of rsync. If it doesn't, the program just will not work at all.

Please note that if you are using IRIX, there is another program named rsync that is different than the “real†rsync most people know of. If you're on an IRIX machine, you should double check this.

cmd_ssh

If you have ssh installed on your system, you will want to uncomment the cmd_ssh parameter. By enabling ssh, you can take snapshots of any number of remote systems. If you don't have ssh, or plan to only take snapshots of the local filesystem, you may safely leave this commented out.

cmd_logger

The cmd_logger parameter specifies the path to the logger program. logger is a command line interface to syslog. See the logger man page for more details. logger should be a standard part of most UNIX-like systems. It appears to have remained unchanged since about 1993, which is good for cross-platform stability. If you comment out this parameter, it will disable syslog support in rsnapshot. It is recommended that you leave this enabled.

cmd_du

The cmd_du parameter specifies the path to the du program. du is a command line tool that reports on disk usage. rsnapshot uses du to generate reports about the actual amount of disk space taken up, which is otherwise difficult to estimate because of all the hard links.

If you comment this out, rsnapshot will try to use the version of du it finds in your path, if possible. The GNU version of du is recommended, since it has the best selection of features, and supports the most options. The BSD version also seems to work, although some versions don't support the -h flag. Solaris du does not work at all, because it doesn't support the -c parameter.

link_dest

If you have rsync version 2.5.7 or later, you may want to enable this. With link_dest enabled, rsnapshot relies on rsync to create recursive hard links, overriding GNU cp in most, but not all, cases. With link_dest enabled, every single file on your system can be backed up in one pass, on any operating system. To get the most out of rsnapshot on non-Linux platforms, link_dest should be enabled. Be advised, however, that if a remote host is unavailable during a backup, rsnapshot will take an extra step and roll back the files from the previous backup. Using GNU cp, this would not be necessary.

interval

rsnapshot has no idea how often you want to take snapshots. Everyone's backup scheme may be different. In order to specify how much data to save, you need to tell rsnapshot which “intervals†to keep, and how many of each. An interval, in the context of the rsnapshot config file, is a unit of time measurement. These can actually be named anything (as long as it's alphanumeric, and not a reserved word), but by convention we will call ours hourly and daily. In this example, we want to take a snapshot every four hours, or six times a day (these are the hourly intervals). We also want to keep a second set, which are taken once a day, and stored for a week (or seven days). This happens to be the default, so as you can see the config file reads:

interval    hourly  6
-interval    daily   7

It also has some other entries, but you can either ignore them or comment them out for now.

Please note that the hourly interval is specified first. This is very important. The first interval line is assumed to be the smallest unit of time, with each additional line getting successively larger. Thus, if you add a yearly interval, it should go at the bottom, and if you add a minutes interval, it should go before hourly. It's also worth noting that the snapshots get “pulled up†from the smallest interval to the largest. In this example, the daily snapshots get pulled from the oldest hourly snapshot, not directly from the main filesystem.

backup

Please note that the destination paths specified here are based on the assumption that the --relative flag is being passed to rsync via the rsync_long_args parameter. If you are installing for the first time, this is the default setting. If you upgraded from a previous version, please read the INSTALL file that came with the source distribution for more information.

This is the section where you tell rsnapshot what files you actually want to back up. You put a “backup†parameter first, followed by the full path to the directory or network path you're backing up. The third column is the relative path you want to back up to inside the snapshot root. Let's look at an example:

backup      /etc/      localhost/

In this example, backup tells us it's a backup point. /etc/ is the full path to the directory we want to take snapshots of, and localhost/ is a directory inside the snapshot_root we're going to put them in. Using the word localhost as the destination directory is just a convention. You might also choose to use the server's fully qualified domain name instead of localhost. If you are taking snapshots of several machines on one dedicated backup server, it's a good idea to use their various hostnames as directories to keep track of which files came from which server.

In addition to full paths on the local filesystem, you can also backup remote systems using rsync over ssh. If you have ssh installed and enabled (via the cmd_ssh parameter), you can specify a path like:

backup      root@example.com:/etc/     example.com/

This behaves fundamentally the same way, but you must take a few extra things into account.

  • The ssh daemon must be running on example.com

  • You must have access to the account you specify the remote machine, in this case the root user on example.com.

  • You must have key-based logins enabled for the root user at example.com, without passphrases. If you wanted to perform backups as another user, you could specify the other user instead of root for the source (i.e. user@domain.com). Please note that allowing remote logins with no passphrase is a security risk that may or may not be acceptable in your situation. Make sure you guard access to the backup server very carefully! For more information on how to set this up, please consult the ssh man page, or a tutorial on using ssh public and private keys. You will find that the key based logins are better in many ways, not just for rsnapshot but for convenience and security in general. Troy Johnson's excellent tutorial on using nifty ssh features for secure snapshots which, in case his site ever suffers a mishap, is mirrored here on this site.

  • This backup occurs over the network, so it may be slower. Since this uses rsync, this is most noticeable during the first backup. Depending on how much your data changes, subsequent backups should go much, much faster since rsync only sends the differences between files.

backup_script

With this parameter, the second column is the full path to an executable backup script, and the third column is the local path you want to store it in (just like with the "backup" parameter). For example:

backup_script      /usr/local/bin/backup_pgsql.sh       localhost/postgres/

In this example, rsnapshot will run the script /usr/local/bin/backup_pgsql.sh in a temp directory, then sync the results into the localhost/postgres/ directory under the snapshot root. You can find the backup_pgsql.sh example script in the utils/ directory of the source distribution. Feel free to modify it for your system.

Your backup script simply needs to dump out the contents of whatever it does into it's current working directory. It can create as many files and/or directories as necessary, but it should not put its files in any pre-determined path. The reason for this is that rsnapshot creates a temp directory, changes to that directory, runs the backup script, and then syncs the contents of the temp directory to the local path you specified in the third column. A typical backup script would be one that archives the contents of a database. It might look like this:

#!/bin/sh
-
-/usr/bin/mysqldump -uroot mydatabase > mydatabase.sql
-/bin/chmod 644 mydatabase.sql

There are several example scripts in the utils/ directory of the rsnapshot source distribution to give you more ideas.

Make sure the destination path you specify is unique. The backup script will completely overwrite anything in the destination path, so if you tried to specify the same destination twice, you would be left with only the files from the last script. Fortunately, rsnapshot will try to prevent you from doing this when it reads the config file.

Please remember that these backup scripts will be invoked as the user running rsnapshot. In our example, this is root. Make sure your backup scripts are owned by root, and not writable by anyone else. If you fail to do this, anyone with write access to these backup scripts will be able to put commands in them that will be run as the root user. If they are malicious, they could take over your server.

Testing your config file

When you have made all your changes, you should verify that the config file is syntactically valid, and that all the supporting programs are where you think they are. To do this, run rsnapshot with the configtest argument:

rsnapshot configtest

If all is well, it should say Syntax OK. If there's a problem, it should tell you exactly what it is. Make sure your config file is using tabs and not spaces, etc.

The final step to test your configuration is to run rsnapshot in test mode. This will print out a verbose list of the things it will do, without actually doing them. To do a test run, run this command:

rsnapshot -t hourly

This tells rsnapshot to simulate an "hourly" backup. It should print out the commands it will perform when it runs for real. Please note that the test output might be slightly different than the real execution, but only because the test doesn't actually do things that may be checked for later in the program. For example, if the program will create a directory and then later test to see if that directory exists, the test run might claim that it would create the directory twice, since it didn't actually get created during the test. This should be the only type of difference you will see while running a test.

Automation

Now that you have your config file set up, it's time to set up rsnapshot to be run from cron. As the root user, edit root's crontab by typing:

crontab -e

You could alternately keep a crontab file that you load in, but the concepts are the same. You want to enter the following information into root's crontab:

-0 */4 * * *       /usr/local/bin/rsnapshot hourly
-30 23 * * *       /usr/local/bin/rsnapshot daily
-

It is usually a good idea to schedule the larger intervals to run a bit before the lower ones. For example, in the crontab above, notice that daily runs 30 minutes before hourly. This helps prevent race conditions where the daily would try to run before the hourly job had finished. This same strategy should be extended so that a weekly entry would run before the daily and so on. -

How it works

We have a snapshot root under which all backups are stored. By default, this is the directory /.snapshots/. Within this directory, other directories are created for the various intervals that have been defined. In the beginning it will be empty, but once rsnapshot has been running for a week, it should look something like this:

-[root@localhost]# ls -l /.snapshots/
-drwxr-xr-x    7 root     root         4096 Dec 28 00:00 daily.0
-drwxr-xr-x    7 root     root         4096 Dec 27 00:00 daily.1
-drwxr-xr-x    7 root     root         4096 Dec 26 00:00 daily.2
-drwxr-xr-x    7 root     root         4096 Dec 25 00:00 daily.3
-drwxr-xr-x    7 root     root         4096 Dec 24 00:00 daily.4
-drwxr-xr-x    7 root     root         4096 Dec 23 00:00 daily.5
-drwxr-xr-x    7 root     root         4096 Dec 22 00:00 daily.6
-drwxr-xr-x    7 root     root         4096 Dec 29 00:00 hourly.0
-drwxr-xr-x    7 root     root         4096 Dec 28 20:00 hourly.1
-drwxr-xr-x    7 root     root         4096 Dec 28 16:00 hourly.2
-drwxr-xr-x    7 root     root         4096 Dec 28 12:00 hourly.3
-drwxr-xr-x    7 root     root         4096 Dec 28 08:00 hourly.4
-drwxr-xr-x    7 root     root         4096 Dec 28 04:00 hourly.5
-

Inside each of these directories is a “full†backup of that point in time. The destination directory paths you specified under the backup and backup_script parameters get stuck directly under these directories. In the example:

backup          /etc/           localhost/

The /etc/ directory will initially get backed up into /.snapshots/hourly.0/localhost/etc/

Each subsequent time rsnapshot is run with the hourly command, it will rotate the hourly.X directories, and then “copy†the contents of the hourly.0 directory (using hard links) into hourly.1.

When rsnapshot daily is run, it will rotate all the daily.X directories, then copy the contents of hourly.5 into daily.0.

hourly.0 will always contain the most recent snapshot, and daily.6 will always contain a snapshot from a week ago. Unless the files change between snapshots, the “full†backups are really just multiple hard links to the same files. Thus, if your /etc/passwd file doesn't change in a week, hourly.0/localhost/etc/passwd and daily.6/localhost/etc/passwd will literally be the same exact file. This is how rsnapshot can be so efficient on space. If the file changes at any point, the next backup will unlink the hard link in hourly.0, and replace it with a brand new file. This will now take double the disk space it did before, but it is still considerably less than it would be to have full unique copies of this file 13 times over.

Remember that if you are using different intervals than the ones in this example, the first interval listed is the one that gets updates directly from the main filesystem. All subsequently listed intervals pull from the previous intervals. For example, if you had weekly, monthly, and yearly intervals defined (in that order), the weekly ones would get updated directly from the filesystem, the monthly ones would get updated from weekly, and the yearly ones would get updated from monthly.

Restoring backups

When rsnapshot is first run, it will create the snapshot_root directory (/.snapshots/ by default). It assigns this directory the permissions 700, and for good reason. The snapshot root will probably contain files owned by all sorts of users on your system. If any of these files are writeable (and of course some of them will be), the users will still have write access to their files. Thus, if they can see the snapshots directly, they can modify them, and the integrity of the snapshots can not be guaranteed.

For example, if a user had write permission to the backups and accidentally ran rm -rf /, they would delete all their files in their home directory and all the files they owned in the backups!

root only

The simplest, but least flexible solution, is to simply deny non-root users access to the snapshot root altogether. The root user will still have access of course, and as with all other aspects of system administration, must be trusted not to go messing with things too much. However, by simply denying access to everyone, the root user will be the only one who can pull backups. This may or may not be desirable, depending on your situation. For a small setup or a single-user machine, this may be all you need.

All users

If users need to be able to pull their own backups, you will need to do a little extra work up front (but probably less work in the long run). The best way to do this seems to be creating a container directory for the snapshot root with 700 permissions, giving the snapshot root directory 755 permissions, and mounting the snapshot root for the users read-only. This can be done over NFS and Samba, to name two possibilities. Let's explore how to do this using NFS on a single machine:

Set the snapshot_root variable in /etc/rsnapshot.conf equal to /.private/.snapshots/

snapshot_root       /.private/.snapshots/

Create the container directory:

mkdir /.private/

Create the real snapshot root:

mkdir /.private/.snapshots/

Create the read-only snapshot root mount point:

mkdir /.snapshots/

Set the proper permissions on these new directories:

chmod 0700 /.private/
-chmod 0755 /.private/.snapshots/
-chmod 0755 /.snapshots/

In /etc/exports, add /.private/.snapshots/ as a read only NFS export:

/.private/.snapshots/  127.0.0.1(ro,no_root_squash)

In /etc/fstab, mount /.private/.snapshots/ read-only under /.snapshots/

localhost:/.private/.snapshots/   /.snapshots/   nfs    ro   0 0

You should now restart your NFS daemon.

Now mount the read-only snapshot root:

mount /.snapshots/

To test this, go into the /.snapshots/ directory as root. It is set to read-only, so even root shouldn't be able to write to it. As root, try:

touch /.snapshots/testfile

This should fail, citing insufficient permissions. This is what you want. It means that your users won't be able to mess with the snapshots either.

Now, all your users have to do to recover old files is go into the /.snapshots directory, select the interval they want, and browse through the filesystem until they find the files they are looking for. They can't modify anything in here because NFS will prevent them, but they can copy anything that they had read permission for in the first place. All the regular filesystem permissions are still at work, but the read-only NFS mount prevents any writes from happening.

Please note that some NFS configurations may prevent you from accessing files that are owned by root and set to only be readable by root. In this situation, you may wish to pull backups for root from the "real" snapshot root, and let non-privileged users pull from the read-only NFS mount.

Conclusion

If you followed the instructions in this document, you should now have rsnapshot installed and set up to perform automatic backups of your system. If it's not working, go back and trace your steps back to see if you can isolate the problem.

The amount of disk space taken up will be equal to one full backup, plus an additional copy of every file that is changed. There is also a slight disk space overhead with creating multiple hard links, but it's not very much. On my system, adding a second, completely identical 3 Gigabyte interval alongside the original one only added about 15 Megabytes.

You can use the du option to rsnapshot to generate disk usage reports. To see the sum total of all space used, try:

rsnapshot du

If you were storing backups under localhost/home/ and wanted to see how much this subdirectory takes up throughout all your backups, try this instead:

rsnapshot du localhost/home/

Send your additions, comments and criticisms to the following email address : nathan@rsnapshot.org. - - - - - - Motivation - - I originally used Mike Rubel's shell scripts to do rsync snapshots a while back. These worked very well, but there were a number of things that I wanted to improve upon. I had to write two shell scripts that were customized for my server. If I wanted to change the number of intervals stored, or the parts of the filesystem that were archived, that meant manually editing these shell scripts. If I wanted to install them on a different server with a different configuration, this meant manually editing the scripts for the new server, and hoping the logic and the sequence of operations was correct. Also, I was doing all the backups locally, on a single machine, on a single hard drive (just to protect from dumb user mistakes like deleting files). Never the less, I continued on with this system for a while, and it did work very well. - Several months later, the IDE controller on my web server failed horribly (when I typed /sbin/shutdown, it said the command was not found). I was then faced with what was in the back of my mind all along: I had not been making regular remote backups of my server, and the local backups were of no use to me since the entire drive was corrupted. The reason I had only been making sporadic, partial remote backups is that they weren't automatic and effortless. Of course, this was no one's fault but my own, but I got frustrated enough to write a tool that would make automated remote snapshots so easy that I wouldn't ever have to worry about them again. This goal has long been reached, but work on rsnapshot still continues as people submit patches, request features, and ways are found to improve the program. - - - - - Installation - This section will walk you through the installation of rsnapshot, step by step. This is not the only way to do it, but it is a way that works and that is well documented. Feel free to improvise if you know what you're doing. - - This guide assumes you are installing rsnapshot 1.2.0 for the first time. If you are upgrading from an earlier version, please read the INSTALL file that comes with the source distribution instead. - - - 30 second version (for the impatient) - - ./configure --sysconfdir=/etc -su -make install -cp /etc/rsnapshot.conf.default /etc/rsnapshot.conf - - The rest of this section is the long version. - - - - Untar the source code package - - tar xzvf rsnapshot-1.2.0.tar.gz - - If you don't have GNU tar, you may have to do this in two steps instead: - - gunzip rsnapshot-1.2.0.tar.gz -tar xvf rsnapshot-1.2.0.tar - - - - Change to the source directory - - cd rsnapshot-1.2.0/ - - - - Decide where you want to install - - By default, the installation procedure will install all files under /usr/local. For this tutorial, this will be OK except we will install the config file under /etc. - - We are assuming that rsync, ssh, logger, and du are all in your search path. If this is not the case, you can specify the path to any of these programs using the typical Autoconf --with-program=/path/to/program syntax. For example, if Perl was in /opt/bin/perl and rsync was in /home/me/bin/rsync, you could run configure like: - - ./configure --with-perl=/opt/bin/perl --with-rsync=/home/me/bin/rsync - - - - - Run the configure script - - This will poke and prod your system to figure out where the various external programs that rsnapshot depends on live. It also generates the Makefile that we will use to install the program. The configure script accepts arguments that can be used to tell it where to install the program, and also where to find the supporting programs. For this installation, the only non-default option we want is to put the config file in the /etc directory. To do this, run this command at the shell: - - ./configure --sysconfdir=/etc - - If all goes well, you're ready to install the program. If there was a problem, it should be descriptive. Most likely a problem would be the result of something that was required and not found (like rsync or perl). If this happens, you must figure out where the missing program is located on your system, or install it if necessary. If you know where it is but configure couldn't find it, you can specify the path using the --with-program=/path/to/program options described above. - - - - Install the program - - If you've followed these instructions so far, you will have configured rsnapshot to be installed under /usr/local, with the config file in /etc. Under these circumstances, it will be necessary to become root to install the program. Now is the time to do so. You will, of course, need the root password to do this: - - su - - This will prompt you for the root password. - - Now, to install rsnapshot, run the following command: - - make install - - This will install rsnapshot with all the settings you specified in the ./configure stage. If all goes well, you will have the following files on your system: - - - /usr/local/bin/rsnapshot The rsnapshot program - /usr/local/man/man1/rsnapshot.1 Man page - /etc/rsnapshot.conf.default The example config file - - If you decide later that you don't want rsnapshot on your system anymore, simply remove the files listed above, or run make uninstall in the same source directory you installed from. Of course, if you installed with different options, the location of these files may be different. - - - - - - - Configuration - - - Create the config file - - In the install process, the config file is not created or installed. However, a working example is provided that you can copy. To copy the example config file into the location rsnapshot will be looking for the real config file: - - cp /etc/rsnapshot.conf.default /etc/rsnapshot.conf - - As a general rule, you should avoid modifying /etc/rsnapshot.conf.default, simply because it is a working example that you may wish to refer to later. Also, if you perform an upgrade, the rsnapshot.conf.default file will always be upgraded to the latest version, while your real config file will be safe out of harm's way. Please note that if you run make upgrade during an upgrade, your rsnapshot.conf may be modified slightly, and the original will then be saved in rsnapshot.conf.backup in the same directory. - - - - Where to go for more info - - The rsnapshot.conf config file is well commented, and much of it should be fairly self-explanatory. For a full reference of all the various options, please consult the rsnapshot man page. Type: - - man rsnapshot - - This will give you the complete documentation. However, it assumes that you already know what you're doing to a certain extent. If you just want to get something up and running, this tutorial is a better place to start. If your system can't find the man page, /usr/local/man probably isn't in your $MANPATH environmental variable. This is beyond the scope of this document, but if it isn't working for you, you can always read the newest man page on the rsnapshot web site at http://www.rsnapshot.org/ - - - - - Modifying the config file - - In this example, we will be using the /.snapshots/ directory to hold the filesystem snapshots. This is referred to as the snapshot root. Feel free to put this anywhere you have lots of free disk space. However, the examples in this document assume you have not changed this parameter, so you will have to substitute this in your commands if you put it somewhere else. - Also please note that fields are separated by tabs, not spaces. The reason for this is so it's easier to specify file paths with spaces in them. - - - cmd_cp - - If enabled, the cmd_cp parameter should contain the path to the GNU cp program on your filesystem. If you are using Linux, be sure to uncomment this by removing the hash mark (#) in front of it. If you are using BSD, Solaris, IRIX, or most other UNIX variants, you should leave this commented out. - What makes GNU cp so special is that unlike the traditional UNIX cp, it has the ability to make recursive copies of directories as hard links. - If you don't have GNU cp, there is a subroutine in rsnapshot that somewhat approximates this functionality (although it won't support more esoteric files such as device nodes, FIFOs, sockets, etc). This gets followed up by another call to rsync, which transfers the remaining special files, if any. In this way, rsnapshot can support all file types on every platform. - The rule of thumb is that if you're on a Linux system, leave cmd_cp enabled. If you aren't on a Linux system, leave cmd_cp disabled. There are reports of GNU cp working on BSD and other non-Linux platforms, but there have also been some cases where problems have been encountered. If you enable cmd_cp on a non-Linux platform, please let the mailing list know how it worked out for you. - - - - cmd_rsync - - The cmd_rsync parameter must not be commented out, and it must point to a working version of rsync. If it doesn't, the program just will not work at all. - Please note that if you are using IRIX, there is another program named rsync that is different than the real rsync most people know of. If you're on an IRIX machine, you should double check this. - - - - cmd_ssh - - If you have ssh installed on your system, you will want to uncomment the cmd_ssh parameter. By enabling ssh, you can take snapshots of any number of remote systems. If you don't have ssh, or plan to only take snapshots of the local filesystem, you may safely leave this commented out. - - - - cmd_logger - - The cmd_logger parameter specifies the path to the logger program. logger is a command line interface to syslog. See the logger man page for more details. logger should be a standard part of most UNIX-like systems. It appears to have remained unchanged since about 1993, which is good for cross-platform stability. If you comment out this parameter, it will disable syslog support in rsnapshot. It is recommended that you leave this enabled. - - - - cmd_du - - The cmd_du parameter specifies the path to the du program. du is a command line tool that reports on disk usage. rsnapshot uses du to generate reports about the actual amount of disk space taken up, which is otherwise difficult to estimate because of all the hard links. - If you comment this out, rsnapshot will try to use the version of du it finds in your path, if possible. The GNU version of du is recommended, since it has the best selection of features, and supports the most options. The BSD version also seems to work, although some versions don't support the -h flag. Solaris du does not work at all, because it doesn't support the -c parameter. - - - - link_dest - - If you have rsync version 2.5.7 or later, you may want to enable this. With link_dest enabled, rsnapshot relies on rsync to create recursive hard links, overriding GNU cp in most, but not all, cases. With link_dest enabled, every single file on your system can be backed up in one pass, on any operating system. To get the most out of rsnapshot on non-Linux platforms, link_dest should be enabled. Be advised, however, that if a remote host is unavailable during a backup, rsnapshot will take an extra step and roll back the files from the previous backup. Using GNU cp, this would not be necessary. - - - - interval - - rsnapshot has no idea how often you want to take snapshots. Everyone's backup scheme may be different. In order to specify how much data to save, you need to tell rsnapshot which intervals to keep, and how many of each. An interval, in the context of the rsnapshot config file, is a unit of time measurement. These can actually be named anything (as long as it's alphanumeric, and not a reserved word), but by convention we will call ours hourly and daily. In this example, we want to take a snapshot every four hours, or six times a day (these are the hourly intervals). We also want to keep a second set, which are taken once a day, and stored for a week (or seven days). This happens to be the default, so as you can see the config file reads: - -interval hourly 6 -interval daily 7 - - It also has some other entries, but you can either ignore them or comment them out for now. - Please note that the hourly interval is specified first. This is very important. The first interval line is assumed to be the smallest unit of time, with each additional line getting successively larger. Thus, if you add a yearly interval, it should go at the bottom, and if you add a minutes interval, it should go before hourly. It's also worth noting that the snapshots get pulled up from the smallest interval to the largest. In this example, the daily snapshots get pulled from the oldest hourly snapshot, not directly from the main filesystem. - - - - backup - - Please note that the destination paths specified here are based on the assumption that the --relative flag is being passed to rsync via the rsync_long_args parameter. If you are installing for the first time, this is the default setting. If you upgraded from a previous version, please read the INSTALL file that came with the source distribution for more information. - - This is the section where you tell rsnapshot what files you actually want to back up. You put a backup parameter first, followed by the full path to the directory or network path you're backing up. The third column is the relative path you want to back up to inside the snapshot root. Let's look at an example: - - backup /etc/ localhost/ - - In this example, backup tells us it's a backup point. /etc/ is the full path to the directory we want to take snapshots of, and localhost/ is a directory inside the snapshot_root we're going to put them in. Using the word localhost as the destination directory is just a convention. You might also choose to use the server's fully qualified domain name instead of localhost. If you are taking snapshots of several machines on one dedicated backup server, it's a good idea to use their various hostnames as directories to keep track of which files came from which server. - - In addition to full paths on the local filesystem, you can also backup remote systems using rsync over ssh. If you have ssh installed and enabled (via the cmd_ssh parameter), you can specify a path like: - - backup root@example.com:/etc/ example.com/ - - This behaves fundamentally the same way, but you must take a few extra things into account. - - - The ssh daemon must be running on example.com - You must have access to the account you specify the remote machine, in this case the root user on example.com. - You must have key-based logins enabled for the root user at example.com, without passphrases. If you wanted to perform backups as another user, you could specify the other user instead of root for the source (i.e. user@domain.com). Please note that allowing remote logins with no passphrase is a security risk that may or may not be acceptable in your situation. Make sure you guard access to the backup server very carefully! For more information on how to set this up, please consult the ssh man page, or a tutorial on using ssh public and private keys. You will find that the key based logins are better in many ways, not just for rsnapshot but for convenience and security in general. Troy Johnson's excellent tutorial on using nifty ssh features for secure snapshots which, in case his site ever suffers a mishap, is mirrored here on this site. - This backup occurs over the network, so it may be slower. Since this uses rsync, this is most noticeable during the first backup. Depending on how much your data changes, subsequent backups should go much, much faster since rsync only sends the differences between files. - - - - - backup_script - - With this parameter, the second column is the full path to an executable backup script, and the third column is the local path you want to store it in (just like with the "backup" parameter). For example: - - backup_script /usr/local/bin/backup_pgsql.sh localhost/postgres/ - - In this example, rsnapshot will run the script /usr/local/bin/backup_pgsql.sh in a temp directory, then sync the results into the localhost/postgres/ directory under the snapshot root. You can find the backup_pgsql.sh example script in the utils/ directory of the source distribution. Feel free to modify it for your system. - Your backup script simply needs to dump out the contents of whatever it does into it's current working directory. It can create as many files and/or directories as necessary, but it should not put its files in any pre-determined path. The reason for this is that rsnapshot creates a temp directory, changes to that directory, runs the backup script, and then syncs the contents of the temp directory to the local path you specified in the third column. A typical backup script would be one that archives the contents of a database. It might look like this: - - #!/bin/sh - -/usr/bin/mysqldump -uroot mydatabase > mydatabase.sql -/bin/chmod 644 mydatabase.sql - - There are several example scripts in the utils/ directory of the rsnapshot source distribution to give you more ideas. - - Make sure the destination path you specify is unique. The backup script will completely overwrite anything in the destination path, so if you tried to specify the same destination twice, you would be left with only the files from the last script. Fortunately, rsnapshot will try to prevent you from doing this when it reads the config file. - - Please remember that these backup scripts will be invoked as the user running rsnapshot. In our example, this is root. Make sure your backup scripts are owned by root, and not writable by anyone else. If you fail to do this, anyone with write access to these backup scripts will be able to put commands in them that will be run as the root user. If they are malicious, they could take over your server. - - - - - - Testing your config file - - When you have made all your changes, you should verify that the config file is syntactically valid, and that all the supporting programs are where you think they are. To do this, run rsnapshot with the configtest argument: - - rsnapshot configtest - - If all is well, it should say Syntax OK. If there's a problem, it should tell you exactly what it is. Make sure your config file is using tabs and not spaces, etc. - The final step to test your configuration is to run rsnapshot in test mode. This will print out a verbose list of the things it will do, without actually doing them. To do a test run, run this command: - - rsnapshot -t hourly - - This tells rsnapshot to simulate an "hourly" backup. It should print out the commands it will perform when it runs for real. Please note that the test output might be slightly different than the real execution, but only because the test doesn't actually do things that may be checked for later in the program. For example, if the program will create a directory and then later test to see if that directory exists, the test run might claim that it would create the directory twice, since it didn't actually get created during the test. This should be the only type of difference you will see while running a test. - - - - - - Automation - - Now that you have your config file set up, it's time to set up rsnapshot to be run from cron. As the root user, edit root's crontab by typing: - - crontab -e - - You could alternately keep a crontab file that you load in, but the concepts are the same. You want to enter the following information into root's crontab: - - -0 */4 * * * /usr/local/bin/rsnapshot hourly -30 23 * * * /usr/local/bin/rsnapshot daily - - - It is usually a good idea to schedule the larger intervals to run a bit before the lower ones. For example, in the crontab above, notice that daily runs 30 minutes before hourly. This helps prevent race conditions where the daily would try to run before the hourly job had finished. This same strategy should be extended so that a weekly entry would run before the daily and so on. - - - - - - - How it works - - We have a snapshot root under which all backups are stored. By default, this is the directory /.snapshots/. Within this directory, other directories are created for the various intervals that have been defined. In the beginning it will be empty, but once rsnapshot has been running for a week, it should look something like this: - - -[root@localhost]# ls -l /.snapshots/ -drwxr-xr-x 7 root root 4096 Dec 28 00:00 daily.0 -drwxr-xr-x 7 root root 4096 Dec 27 00:00 daily.1 -drwxr-xr-x 7 root root 4096 Dec 26 00:00 daily.2 -drwxr-xr-x 7 root root 4096 Dec 25 00:00 daily.3 -drwxr-xr-x 7 root root 4096 Dec 24 00:00 daily.4 -drwxr-xr-x 7 root root 4096 Dec 23 00:00 daily.5 -drwxr-xr-x 7 root root 4096 Dec 22 00:00 daily.6 -drwxr-xr-x 7 root root 4096 Dec 29 00:00 hourly.0 -drwxr-xr-x 7 root root 4096 Dec 28 20:00 hourly.1 -drwxr-xr-x 7 root root 4096 Dec 28 16:00 hourly.2 -drwxr-xr-x 7 root root 4096 Dec 28 12:00 hourly.3 -drwxr-xr-x 7 root root 4096 Dec 28 08:00 hourly.4 -drwxr-xr-x 7 root root 4096 Dec 28 04:00 hourly.5 - - - Inside each of these directories is a full backup of that point in time. The destination directory paths you specified under the backup and backup_script parameters get stuck directly under these directories. In the example: - - backup /etc/ localhost/ - - The /etc/ directory will initially get backed up into /.snapshots/hourly.0/localhost/etc/ - - Each subsequent time rsnapshot is run with the hourly command, it will rotate the hourly.X directories, and then copy the contents of the hourly.0 directory (using hard links) into hourly.1. - When rsnapshot daily is run, it will rotate all the daily.X directories, then copy the contents of hourly.5 into daily.0. - hourly.0 will always contain the most recent snapshot, and daily.6 will always contain a snapshot from a week ago. Unless the files change between snapshots, the full backups are really just multiple hard links to the same files. Thus, if your /etc/passwd file doesn't change in a week, hourly.0/localhost/etc/passwd and daily.6/localhost/etc/passwd will literally be the same exact file. This is how rsnapshot can be so efficient on space. If the file changes at any point, the next backup will unlink the hard link in hourly.0, and replace it with a brand new file. This will now take double the disk space it did before, but it is still considerably less than it would be to have full unique copies of this file 13 times over. - Remember that if you are using different intervals than the ones in this example, the first interval listed is the one that gets updates directly from the main filesystem. All subsequently listed intervals pull from the previous intervals. For example, if you had weekly, monthly, and yearly intervals defined (in that order), the weekly ones would get updated directly from the filesystem, the monthly ones would get updated from weekly, and the yearly ones would get updated from monthly. - - - - - Restoring backups - - When rsnapshot is first run, it will create the snapshot_root directory (/.snapshots/ by default). It assigns this directory the permissions 700, and for good reason. The snapshot root will probably contain files owned by all sorts of users on your system. If any of these files are writeable (and of course some of them will be), the users will still have write access to their files. Thus, if they can see the snapshots directly, they can modify them, and the integrity of the snapshots can not be guaranteed. - - For example, if a user had write permission to the backups and accidentally ran rm -rf /, they would delete all their files in their home directory and all the files they owned in the backups! - - - root only - - The simplest, but least flexible solution, is to simply deny non-root users access to the snapshot root altogether. The root user will still have access of course, and as with all other aspects of system administration, must be trusted not to go messing with things too much. However, by simply denying access to everyone, the root user will be the only one who can pull backups. This may or may not be desirable, depending on your situation. For a small setup or a single-user machine, this may be all you need. - - - - All users - - If users need to be able to pull their own backups, you will need to do a little extra work up front (but probably less work in the long run). The best way to do this seems to be creating a container directory for the snapshot root with 700 permissions, giving the snapshot root directory 755 permissions, and mounting the snapshot root for the users read-only. This can be done over NFS and Samba, to name two possibilities. Let's explore how to do this using NFS on a single machine: - - Set the snapshot_root variable in /etc/rsnapshot.conf equal to /.private/.snapshots/ - snapshot_root /.private/.snapshots/ - - - Create the container directory: - mkdir /.private/ - - Create the real snapshot root: - mkdir /.private/.snapshots/ - - Create the read-only snapshot root mount point: - mkdir /.snapshots/ - - Set the proper permissions on these new directories: - chmod 0700 /.private/ -chmod 0755 /.private/.snapshots/ -chmod 0755 /.snapshots/ - - In /etc/exports, add /.private/.snapshots/ as a read only NFS export: - - /.private/.snapshots/ 127.0.0.1(ro,no_root_squash) - - In /etc/fstab, mount /.private/.snapshots/ read-only under /.snapshots/ - - localhost:/.private/.snapshots/ /.snapshots/ nfs ro 0 0 - - You should now restart your NFS daemon. - - Now mount the read-only snapshot root: - - mount /.snapshots/ - - To test this, go into the /.snapshots/ directory as root. It is set to read-only, so even root shouldn't be able to write to it. As root, try: - - touch /.snapshots/testfile - - This should fail, citing insufficient permissions. This is what you want. It means that your users won't be able to mess with the snapshots either. - Now, all your users have to do to recover old files is go into the /.snapshots directory, select the interval they want, and browse through the filesystem until they find the files they are looking for. They can't modify anything in here because NFS will prevent them, but they can copy anything that they had read permission for in the first place. All the regular filesystem permissions are still at work, but the read-only NFS mount prevents any writes from happening. - Please note that some NFS configurations may prevent you from accessing files that are owned by root and set to only be readable by root. In this situation, you may wish to pull backups for root from the "real" snapshot root, and let non-privileged users pull from the read-only NFS mount. - - - - - - Conclusion - - If you followed the instructions in this document, you should now have rsnapshot installed and set up to perform automatic backups of your system. If it's not working, go back and trace your steps back to see if you can isolate the problem. - The amount of disk space taken up will be equal to one full backup, plus an additional copy of every file that is changed. There is also a slight disk space overhead with creating multiple hard links, but it's not very much. On my system, adding a second, completely identical 3 Gigabyte interval alongside the original one only added about 15 Megabytes. - You can use the du option to rsnapshot to generate disk usage reports.
