How do you effectively backup your high capacity (20+ TB) local NAS? (lemmy.world)

I have a 56 TB local Unraid NAS that is parity protected against single drive failure, and while I think a single drive failing and being parity recovered covers data loss 95% of the time, I'm always concerned about two drives failing or a site-/system-wide disaster that takes out the whole NAS.

For other larger local hosters who are smarter and more prepared, what do you do? Do you sync it off site? How do you deal with cost and bandwidth needs if so? What other backup strategies do you use?

(Sorry if this standard scenario has been discussed - searching didn't turn up anything.)

Backblaze personal doesn't support Linux or BSD, so it would be useless for a NAS.

There are many ways to skin the cat. Here's just one:

This Docker container runs the Backblaze personal backup client via WINE, so that you can back up your files with the separation and portability capabilities of Docker on Linux.

It runs the Backblaze client and starts a virtual X server and a VNC server with Web GUI, so that you can interact with it.

There are also other apps that will 'fool', for a lack of a better word, Backblaze to think a NAS drive is physically connected.

better would be something that can just eat a zfs send stream, but I guess for an emergency it's fine. but I would still want to encrypt everything somehow.
