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.

What platform?

Another user said it - what your asking for isn't a backup, it's just data transfer.

It sounds like you're looking for a storage backend that hosts all your data and can download data to the client side on the fly.

If your use case is Windows, Nextcloud Desktop may be what you looking for. I have a similar setup with the game clips folder. It detects changes and auto uploads then, while deleting less recently used data that's properly server side. This feature might be in Mac but I haven't tested it.

Backup wise, I capture an rsync of the nextcloud database and filesystem server-side and store it on a different chassis. That then gets backed up again to a USB drive I can grab and run.

Nextcloud also supports external storage, which the server directly connects to: https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/external_storage_configuration_gui.html
