What is your preferred method for backing up several TB of data? (lemmy.ml)

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.

So i understood you just want some local storage system with some fault tolerance.
ZFS will do that. Nothing fancy, just volumes as either blockdevice or ZFS filesystem.

If you want something more fancy, maybe even distributed, check out storage cluster systems with erasure coding, less storage wasted than with pure replication, though comes at reconstruction cost if something goes wrong.

MinIO comes to mind, tough i never used it.. my requirements seem to be so rare, these tools only get close :/
afaik you can add more disks and nodes more or less dynamically with it.

Yeah it's hard to find something that perfectly fits just what you want. I think it's better if I do something simple like ZFS and maybe some kind of file server on top.
