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.

All of my machines back up to my home server’s RAID over WebDAV with Nephele.

Then every few days I’ll manually sync them to a server at my parents’ house with a single huge HDD using rsync. I do this manually so that if anything happens to my home server (like ransomware) it doesn’t mirror destroyed data.

Since the Nephele share is just WebDAV, I can mount it locally and move things into it that I don’t want local anymore.

I created Nephele, and I just finished writing an encryption plugin. I wrote it because I’m also going to write an S3 adapter. That way, you can store things in S3, but they’ll be encrypted, so Amazon can’t see them.

Wouldn't syncing automatically every few days give you the same protection though?

Protection against if it happens and they have not noticed within those few days. Probably especially important if they leave the system running while on vacation.

I’m assuming I would notice, because none of my services on the machine would work anymore.

This is really cool. I ended up trying something similar: serving from a ZFS pool with SeaweedFS. TBD if that's going to work for me long term.

I would definitely be able to manually sync the SeaweedFS files with rsync to another location but from what I see it requires me to use their software to make sense of any structure. I might be able to mount it and sync that way, hopefully performance for that is not too bad.

Syncing like that and having more control over where the files are placed on the RAID is very cool.
