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 have 2 500GB SSDs in RAID1 for important data, truenas apps etc…, then 32TB total in RAIDZ1 for large Dataset that won’t need speed (movies, TV show, music, pictures, archives,…)

    If I have a complete NAS failure, a remote backup (via rsync to a friend’s NAS Weekly) of the SSD and bootable drive can be used in a new system, and my torrent app has the list and magnet of all torrents stored on the SSD so it can re-download them.
