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’ve been following this post since the first comment.
And I have just put together my own RAID1 1TB NAS. And I did not think that 1TB will serve me forever, more like “a good start”.
But the numbers I’ve been seeing in here… you guys are nuts 😆
