Agreed, it shouldn't matter, its nothing but stored data

And hardly call rsync "hot backup"

my vote is snapmirror, same DC protected by many CCT cameras,  area
dependant swipe and biometric entry, VESDA, tonnes of FM200, redundant
generators, is 200 mtrs from the second largest fire station in the
state, and 90 mtrs from police HQ.
not on a flood plain, chances earthquakes pretty much zero, redundant
fibre, carriers and microwave, the only thing without redundancy is the
espresso machine, but we working on that one! :)  so who needs
off-site ... wont get close enough with a bomb, and many taller
buildings in the way for a plane, and besides, terrorists likely have
better targets.
