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.
