One of the "lessons learned" after 9/11/2001 was to contemplate the total
grounding of all aviation. Very few saw that one coming! If your enterprise
spans several time zones, you probably want to investigate solutions that
work well over extended distances and do not require physical tape
handling. And by "extended distance" I mean greater than 200 miles.

We had a mechanism in place to do XRC from Chicago to Philiadelphia
during the "Great Flood" of Chicago, in 1992. We soon discarded it
because of the difficulties and performance impact of that sort of
extension. We eventually settled for recovery over a distance of about
35 miles "as the crow flies", again using XRC. It worked well for DR
exercises but we never again had a "real" disaster that would have
stressed it and made it really work.
