New features
Percona XtraBackup has implemented new xtrabackup --remove-original option that can be used to remove the encrypted and compressed files once they’ve been decrypted/decompressed.
Bugs Fixed
xtrabackup was using username set for server in a configuration file even if a different user was defined in the users configuration file. Bug fixed #1551706.
Incremental backups did not include xtrabackup_binlog_info and xtrabackup_galera_info files. Bug fixed #1643803.
In case a warning was written to stout instead of stderr during the streaming backup, it could cause assertion in the xbstream. Bug fixed #1647340.
xtrabackup --move-back did not always restore out-of-datadir tablespaces to their original directories. Bug fixed #1648322.
innobackupex and xtrabackup scripts were showing the password in the ps output when it was passed as a command line argument. Bug fixed #907280
Incremental backup would fail with path like ~/backup/inc_1 because xtrabackup didn’t properly expand tilde. Bug fixed #1642826.
Fixed missing dependency check for Perl Digest::MD5 in rpm packages. This will now require perl-MD5 package to be installed from EPEL repositories on CentOS 5 and CentOS 6 (along with libev). Bug fixed #1644018.
Percona XtraBackup now supports -H, -h, -u and -p shortcuts for --hostname, --datadir, --user and --password respectively. Bugs fixed #1655438 and #1652044.
Other bugs fixed: #1655278.
