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.)

It is cheap as long as you don't need to restore your data. Downloading data from S3 costs a lot. OP asked about 56TB of storage, for which data retrieval would cost about 4.7k

    I'm aware, but I myself have < 3TB and if I actually need it I'll be more happy to pay. It's my "backup of last resort", I keep other backups on site and infrequently on a portable HDD offsite.
