You're doing the 3-2-1 rule wrong, and it's not even close.

You're doing the 3-2-1 rule wrong, and it's not even close.
Most people brag about 3-2-1 then keep all three copies in the same building. That's not 3-2-1, that's three ways to lose everything in one fire. The rule is 3 copies, on 2 different media types, with 1 truly offsite. "Offsite" doesn't mean a second drive in the same server room. It means a different physical location with a different failure domain. A flood, a power surge, a building fire, one landlord lockout — and your "three copies" vanish together. Geography is the whole point. Fight me in the comments.
