Lost my data when I restarted

My Macbook Pro froze while I was writing in DEVONthink. I had been doing a timed exercise, so I know it took me 20 minutes. While I was reviewing it, everything froze. I used the power key to close down. I know there’s a sequence of keys but I forgot it.
After I came back up, i accessed the file and it was blank. DT didn’t save my work even though I’d been in the file for half an hour. How did this happen? I’ve always gotten my work back after a crash.

What kind of file did you actually edit? DEVONthink usually autosaves documents after…

  • 5 minutes of idle time
  • switching to another app
  • switching to another window
  • before synchronizing

It was a rich text document. I know DT saves often because I sometimes don’t get the “do you want to save” dialog when I close a document where I haven’t made a change in a while. I had the file open when I restarted. When I went back, it was blank.

In case of a frozen computer journaling of filesystems (e.g. APFS, HFS+) ensures a valid filesystem but not necessarily valid files. Do you use DEVONthink 3 or 4? If it’s DEVONthink 4, did you enable versioning for this database?

I’ve since written something in that file and saved it. Probably should have renamed it first.

It’s DT 3. I don’t know what versioning is. Thanks for your suggestion.

It’s an optional feature of DEVONthink 4 that keeps the last n versions of modified documents. Similar to Time Machine.
