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

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.)

I don’t. Of my 120tb, I only care about the 4tb of personal data and I push that to a cloud backup. The rest can just be downloaded again.

Do you have logs or software that keeps track of what you need to redownload? A big stress for me with that method is remembering or keeping track of what is lost when I and software can’t even see the filesystem anymore.

That should be part of the backup configuration. You select in the backup tool of choice what you backup. When you poose your array then you download that stuff again?
