Here is some unsolicited advice:  I would strongly recommend that you 
make it a higher priority to have backups available.  In my experience 
computer hardware is becoming quite reliable, but software isn't, and 
the person next to the keyboard isn't either.  (My last desperate need 
for a backup was due to a hardware failure 2 years ago, but it wasn't 
the manufacturer's fault:  my laptop accidentally drowned.)

Backups can save you a lot of grief in the event of a mistake, or a 
software or hardware failure.  But even in the case of routine events 
like software updates that don't go as planned, they can save time.
