My off-prem backups are in a Tailscale connected NAS at my parent's house. I'm in the process of talking a friend into having Tailscale configured to host more off-prem backups at his place as well. I'm moving out of iCloud for photo library management and into Immich. I really don't want to lose my photos and videos hence the off-prem backups. Tailscale has been a blessing for this kind of use case
Oooo. That's the other thing I need to figure out, because it's 90% for my photography. How have you liked immich? Have you tried any other options?
I'm in the process of moving all my backups to Immich - honestly it's best in class software.
I'm able to set it up so that my SO and I can view all the pictures taken by the other (mostly cute photos of our dog and kid, but makes it easier to share them with others when we don't have to worry about what device they're on), have it set to auto-backup, and routed through my VPS so it's available effectively worldwide.
The only issue that I run into is a recent one, which is hard drive space - I've got it on a NAS/RAID setup with backups sent to another NAS at my parents' place, but it's an expensive drive replacement in current market conditions.
I recommend Ente photos, harder to setup but feels much more robust and its end to end encrypted, which I prefer.
I can also recommend Ente. It is pretty polished. Go-based backend using Postgres DB, Flutter-based android version, React-based web frontend (electron for desktop).
