I have it running on a proxmox server on a nvme ssd. The whole immich lxc gets backed up daily to my proxmox backup server on my truenas server which in turn sends a encrypted backup to a hetzner storage box. The setup is pretty much set and forget. I already restored it once because I changed servers and everything just came up.

Maybe something like this? keeper.sh

I installed fedora workstation on the computer of the mother of my wife. It just works. I set google chrome on autoboot and told her, if there is a pop up that says update system klick yes. Never had a single problem with it.
