I'm not sure I will ever upgrade Immich again. When I upgraded to the next minor version (I forget which off the top of my head), the data migration corrupted my database such that no images would be served. Fortunately I had the old database backed up, so I restored it, rolled back to the older version of Immich, and things were back to normal. I like Immich, but this is not good for software that's beyond the first major version, and also handles archiving people's personal data.

You say this as if it wasn’t Immich itself that backed up the database automatically next to your image files.

I think they’re one of the best self-hosted services when it comes to backup/restore — enabling it by default — and when it comes to migrations — no breaking changes in minor versions after 1.0.

Did you report this issue so I could try and reproduce it?

I had an issue where my thumbnails were borked somehow, so I deleted them all. However, I didn't delete the database entries, so they never got regenerated.

I ended up doing that manually, but it's great to see that is now a first class citizen in 3.0.0. I love Immich.
