My goal is to to fully ditch Google Photos for Immich. I have about ~3TB of photos and videos. Looking for a super simple way of backing up the library to cloud storage in case of a drive failure without spending a ton.

Ideally, this will require nothing on my part besides copying files into a given folder. And ideally the storage will be encrypted and have basic privacy assurances.

Also if it matters my home server is running Debian. But I'd prefer something that runs in docker so I can more easily check on it remotely.
