What storage software could I run to have an archive of my personal files (a couple TB of photos) that doesn’t require I keep a full local copy of all the data? I like the idea of a simple and focused tool like Syncthing, but they seem to be angling towards replication.
Is the simple choice to run some S3-like backend and use CLI or other client to append and browse files? I’d love something with fault tolerance that someone can gradually add disks to. If ceph were either less complicated or used less resources I’d want to do that.
Borg Backup. It can work locally or over network. Takes snapshots of the files you give it. Performs deduplication, compression and optionally encryption. You can check the integrity of the backups and repair them. There’s a very simple to use GUI for it called Pika Backup to get you started.
