Warning of Libreoffice peculiarity ...
I just did a dumb thing. I was working on a paper in Libreoffice, opened an earlier version to extract something, kept working on what I suddenly thought was the wrong version so closed it without saving changes. Only to realise I'd closed the wrong one! It wasn't long at the machine, but the stuff was gold! lol
Anyway, thinking all is good as it did an autosave while I was sitting there thinking, I closed Libreoffice (perhaps the second mistake), went to the folder where the autosaved versions should be. Nothing. Zilch. Empty. I'm shattered but don't want anyone else to be.
I know there is no way to get the data back, my fault and all, but that is a serious bug. Think I'll look into filing a bug report or see if there is one anywhere. Openoffice was always faultless for me in all other Ubuntu's. Since the switch in 12.04 Libreoffice has been glitchy and Openoffice is a nightmare to install now, which is why I'm using LO.

You can install AOO and LibO with the .debs downloaded directly from the official web sites. Note that this way you can install and run both applications in parallel. But you need to remove the packages coming with the Ubuntu out of the box configuration first.
See: [Ubuntu] Installing OOo on Debian and Co.
AutoSave is only used in case of crash. As soon as you close correctly the file, those temporary files are deleted.
