Sorry, but I don't see any benefit to having maximum 12 hour old data when
you could have 0. The hardware solution you mentioned was RAID 1 anyway.
Easiest thing to do is use it, and have both spare drives and spare machines
ready to roll should you need to swap either.

Well, there's your benefit to having old data. Who's to say you're going to
know within 12 hours? This is not a particularly interesting problem, mostly
because you're not curing the disease, you're trying to clean up after
infection.
