Hi,
I was working in Writer with an .odt document yesterday, was saving it regularly, but today it looks like I did nothing!
I think, the reason is in me accidantally saving it in /tmp all the time (according to Recently opened documents in LO). I recovered all files from /tmp using testdisk, but couldn’t find anything, that would look like an edited file, only the old version. Automatical backup is supposed to be turned on, so I tried looking in the backup folder, but it contained only empty files. No it was actually off 
Turned it on now.
Any ideas, what other options I might have to recover the file?
I use Ubuntu 13.04 x64 (russian locale), LO 4.0.2.2.
