Doing a volume like the default Immich docker-compose uses should work fine, even through restarts. I’m not sure why your setup is blowing up the volume.
Normally volumes are only removed if there is no running container associated with it, and you manually run docker volume prune
That makes sense, if archiving saves space then it’s just removing/uninstalling the app, but leaving the icon behind. Since you’ve manually installed the app from obtainium, it can’t do that because it has no idea how to re-install the app when you need it again.
