Bug Description

Last week I created an openoffice spreadsheet on my desktop pc in the Ubuntu One folder. I saved regularly as I did lots of mods. Today I look in my Ubuntu One folder and find the file is now 0 bytes long.

The log contains sensitive information and as such I'd like to mail the log to a Canonical person rather than attach to this bug report.

John, Alan mentioned in IRC that his computer has been shutting down abrubtly without warning, and that may have happened over the weekend. It would be good to look at the logs to figure out exactly what events the syncdaemon saw, and whether there is anything we could do better to help avoid data loss. If reviewing the logs shows that the syncdaemon acted correctly given what events happened in the OS, then this is not a critical bug, but I'm marking it as critical until a review is done.

I wish there was a 'can't fix' status. From the detailed log analysis that was done, it looks like the syncdaemon did exactly the right thing - the file was zero bytes when the machine started back up, and it happily truncated the file on the server.

Given that there are situations like this where software corrupts files, or people delete files by mistake, I think this bug emphasizes the importance for Ubuntu One to have a file history and undelete feature on our servers. It will take a bit of a design, but I'll be advocating that we assign engineers to work on developing this history feature for Lucid.

Alan, thanks for your gracious assistance on IRC as we investigated this bug, and I'm very sorry you lost data. I'm closing the bug as wontfix as I don't think there is any further action we can take on this specific bug report.
