What I’m trying to do

After having a system crash, my then open base, including all related documents, were nowhere to be found afterwards.

Things I have tried

After browsing the system for .base and .md data, and not having an option to load a matching backup via the integrated backup-tool I read change logs and found the following irregularity corresponding with the timing of the system crash:

Any idea if there could have been an overwrite or otherwise leak of data happening here? And if so, any aproach to recovering the data? (as I am not allowed to sync my data in my work environment this backup option is not available)

Where was you vault located?

edit to explain why I asked:

If your vault was in Obsidian’s installation folder, C:\Users\erm\AppData\Roaming\obsidian\, know that the location can get overwritten with updates, just like with almost any app.

there is nothing wrong with that log. It just checking for updates.

As for options within obsidian, you can try File Recovery plugin, or if you have sync, sync version history.

We recommend you have a separate backup solution.
