How do you effectively backup your high (20+ TB) local NAS?

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.)

So being encrypted before transmission and at rest isn’t enough simply because someone at backblaze can send the encrypted files out to you on a HDD……..

do NOT open SMB to the internet. You will get crypto’d in minutes. Just a warning for any newbs coming here.
