I'd suggest that it points out the value of a good, tested, known to 
work recovery plan, that people actually know how to use.  A machine 
going up in smoke shouldn't require an outage longer than the time it 
takes to replace the hardware, install an os, and restore from the 
backup media.  Having to muck around trying to figure out how to get 
stuff off tape is no fun.  Having to do it while the boss is screaming 
at you is less fun.

Backup is easy.  Backup is usually done well enough (if it's done at 
all, but only idiots don't).  Recovery is much harder, much less likely 
to have  been tested properly, much less likely to be documented outside 
the head of the guy who sort of though about it, and much less likely to 
be practiced.
