Recover file after PC crash

[meems]

is this the right forum for libreWriter?

can anyone help?

Today my laptop PC crashed hard. I was working on a LibreOffice file. When I rebooted the PC, LibreOffice could not recover a recent state of my document. It recovered a version that was 3 days old. Not satisfied with this I closed this recovered document without saving it and opened my saved file, but then I saw my file was 2 weeks old. I don't know where my saves of the last 2 weeks have gone. Perhaps Windows 10 did a hard rollback when recovering from the crash?
I looked in the libreoffice backup directory but there were no files there. I am resigned to losing the last 2 days work, but I would like to get back the version from 3 days ago, which LibreOffice managed to intially recover but has now seemingly vanished. I screened my PC for recent version of my file, but there was nothing. The best I could find was libreOffice had created a dmp file in the crash folder dated today. Can my document be recovered from this dmp file?

As soon as possible try the methods in this tutorial for detailed instructions on how to

a) use Previous Versions (W7 and later) to recover previous versions of the file.

b) recover your file as it was when you last opened or saved it, or as it was when it was last saved with AutoRecovery;

c) find previous versions of the file in the folder it is located in, but which have since been deleted;

d) un-delete the temporary files AOO wrote while you were editing the file, and then deleted. This may recover your file as it was when you last opened or you last saved it.

Thanks. I tried the tutorial and I downloaded recurva. Even though I've got autosave and backup set, the LibreOffice backup directory was empty. Recurva found only one deleted file and that was overwritten by a junk file shortly after the reboot. The windows stealth rollback had deleted all my revisions of my file of the last 2 weeks. I didn't know windows could do stealth rollbacks. But really I should have been backing-up my work to cope with the loss of my laptop, so I should have able to cope with this. Don't know why my flash disk hadn't saved anything since early December. I had been saving to it every week. Guess I need to start a new habit of saving my work to the internet.

edit: I tried 'previous versions' but windows says there are no previous versions available for my file. Not from the last 2 weeks and not from before the 2 week old version. Quite how Windows has contrived to delete all history of the file, I dunno.

At the time I was using Windows, I was not quite confident in the rollback feature. Could do more harm than good.
I would not backup files on the internet. Personally I use an old hard drive as an external backup device (the HD from an old laptop, I just had to buy a case with the required connectors and a USB cable to plug it). Every now and then I make a backup. I used to use a backup application that can handle versioning but noticed that actually, I never had to check for a different version than the last one. Thus I now use freefilesync, which is pretty good.
