Oooooo, I don't think I'd do that!!!!!  It's akin to saying, "I
don't need to make backups, because I have RAID[1,5,10,1+0]

If the power is out for 26 minutes and your UPS only lasts for 25
minutes, you could be in be in for a long, painful boot process if
the box crashes.  (For example, the UPS auto-shutdown daemon doesn't
work properly, and no one can get to the console to shut it down
properly before the batteries die.)
