Please don't take this personally - since the above is a fairly common thing
to happen, but if you never really tested in a real environment then how
(unless you have recently survived a disaster) do you know you have a sound
DR solution.

We have a 'sound' fire procedure where I work, when we actually tested it
about a year back we found it took 8 minutes to evacuate the (3 floor)
building and 20 to account for everyone. In other words testing the real
procedure in the real environment showed us some problems. DR is much the
same. You have to, regularly, test it for it to be worth the monetary
investment in setting it up.
