Power outages are rare in my neighborhood, but the other day, while I was working in a document on LibreOffice 5.3, a split-second outage made my computer shut down. I was not worried too much because I had the precaution of setting a 10-minute auto backup and saved the document myself more often. Power outages had happened to me dozens of times while working on OpenOffice and other word processors, and the file recovery process was always capable of recovering most of the work. When I turned the computer on again and opened the app the usual recovery window appeared (like on other word processors) informing me of the recovery process. I followed the steps carefully and expected to lose only a few minutes of work, since I had saved the document myself more often than every 10 minutes, right?
Wrong! In the document that opened there were several pages of work missing. It was almost the same document I had opened hours ago. Several hours of hard work just gone. I was unable to find any backup of temp file or retrieve an earlier version. I couldn’t believe that happened.
My questions are if I can recover the previous version of the document, if possible. I also would want to know how did that happen? How can I prevent LibreOffice of doing the same thing again?
I could buy an UPS but that doesn’t address the issue. Saving every document simultaneously to a flash memory is too distracting and time consuming, and I don’t know why I should do it, up till now I have never needed to do that.
Thanks for any help
