I don't care how good your DR plan is on paper, it's just fantasy and theory until you actually test it out. My company currently thinks it's a good idea to make another branch 12 miles away the "DR Site" even though that branch is on a peninsula. Also, their idea of a disaster is a hurricane, fire, flood or tornado for which they calculated a 24 hour RTO. Well, that's fine, but what about a fried HDD controller or motherboard? Will the 24 hour RTO still be respected?

That's why I've been pushing for a multi-tiered DR plan one that covers both hardware "disasters" and natural disasters with the appropriate RTO's for each situation and disaster drills. Like fire drills, I know it will piss people off to be inconvenienced for a little bit, and it's hard to get humans to care about something until it actually happens (and it's too late), but I would be derelict in my duty if I did otherwise.
