Gasthof is what OP is looking for.

I sync them to out local fileserver using syncthing and recently started using immich (since it supports custom libraries now)

I was a rsync.net user for many years and recently switched to borgbase, because of how easy it is to manage multiple backup targets.

RAID is not a backup. I’m not sure about syncthing, does that count as backup? Have you tried restoring from it?
