What I’m trying to do
I am trying to use my Obsidian vault on my personal Windows 11 laptop. The vault was somewhat large (over 1,500 notes). I have Obsidian Sync and do not use any other syncing service for my vault. The vault is saved in the C:\Users[username]\Documents\Obsidian\ directory, and until today, I’d had no problems. Now, almost all of my notes have vanished; I think the only ones left are the five most recent daily notes, five new notes I made yesterday, and, weirdly, all the notes associated with the Readwise plugin. I installed the Readwise plugin on December 31, and December 31 is the last daily note that remains in my vault, but everything was fine until today.
I do manual backups of my vault every once in a while, so I can recover almost everything, but my most recent backup was on December 27, and I did a lot (!) of work between then and now – I probably took 100 new notes on many hours of research. I know I should back up more often. Is there any way I can get my lost data back?
Things I have tried
I have checked whether Obsidian was updated recently (it was not) and looked in my OneDrive and Dropbox accounts to make sure I didn’t accidentally save my vault there and cause a syncing conflict. I did not. I’m not sure what else to try, but I would very much like to get my work back. Please excuse me if someone has already asked about this problem in the forum; I checked and didn’t find anyone with the same details (most but not all files gone overnight). Thank you.
