Immich has been updated and started from scratch.

Hi Waldyr_Dias and welcome.

I am sorry about this situation. Maybe not all is lost. Lets examine it.

Dokcer version of Immich (without machine learning) has 3 containers: server itself, redis cache and PostgreSQL.

My DB has volume path on Host:

/DATA/AppData/big-bear-immich/pgdata

and size is in my case 310 MB.

Upload folder for photos/vids:

/DATA/AppData/big-bear-immich/upload

size is in my case 19 GB.

So, please go here and explore Your size and content:

sudo -i
cd /DATA/AppData/big-bear-immich/pgdata
du -hs
ls -l # or mc
cd ../upload
du -hs
ls -l # or mc

I hope, that Your data are still there, just not connected to actual container instance.

Write reply about Your situation and we can continue.
