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 your whole point is that you shouldn’t trust one of the biggest cloud backup companies on the planet when they say that your data is encrypted, with no proof that they’re telling lies…and you’re asking me to prove that they’re telling the truth?
The onus is on you to prove that they’re telling lies, not on me to prove what they say is true.
They say this about computer backup on one of the pages I linked earlier:
Is that all a lie? Based on what?
No.
I’m saying 99.999999999999999999999999999999999999999999999999999999% ≠ 100%
For some people that’s close enough. For some of us it’s not.
Prove otherwise. I dare you. I’m done putting in effort explaining the obvius to you. Your turn.
