I put all non-text files into attachment/ subdirectory in Obsidian Vault. And on Feb 2nd, 2026, all files in all attachment/ directories were mysteriously deleted. And I didn't find out until today.

I only keep backups for 30 days on the cloud, so that copy is already gone. Syncthing automatically deleted them on all my clients, and I didn't have file versioning enabled.

99% of them are photos - that means I do have a copy in Immich (and S3 backup). But trying to find them one by one would be a pain.

Lesson learnt: Enable Syncthing file versioning. Check valuable assets regularly. Keep a cheap, local backup that can be kept for longer.

Now I'm going to find those pictures based on when the note was created and what they say. Fun.

I think I found a reasonable explanation why the attachments in the obsidian were mysteriously deleted: the photos app on the phones.

I clean up photos on the phone regularly that have already been backed up. When the sync of the vault happened for the first time, the attachments were synced and the back up were enabled automatically for these folders for either Google Photos or iCloud - I can’t remember exactly which one. Then I cleaned them up. So Syncthing did what it supposed to do: it deleted all of them from my source of truth - the vault on my NAS. I didn’t realize that and I don’t look at these old notes enough to find out until two months later.
