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.)


That’s an incredibly good point. Bad actors are the worst. Some ideas:
Definitely a difficult problem to solve. I’m sure people smarter than me have ideas beyond mine.
and also accounting for low bandwidth connections… whats more, some shitty providers even have monthly data caps
yeah, that would be almost a necessary feature. being able to hold on to the backup when you really can’t restore.
