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.)

Like others, I have a 2 tier system.

About 2TB of my (Synology) NAS is critical files. Those get sent via Hyperbackup to cloud storage on at least a weekly basis, some daily. I have them broken up into multiple tasks with staggered schedules so it never has much to do on any given day.

The other 16TB I have get sync'd (again with hyperbackup, but not a scheduled backup task) to a 20TB external drive roughly once per quarter. Then that drive lives on the closet of a family member.
