Ah.  I bet there are more than a few people here who can repeat a horror story 
about what happened when a long running server was shut down.

I remember several years ago we had a HP server at work that had been running 
nonstop for about three years.   One day, due to a major electrical upgrade 
in the computer room, the sysadmin had to cold start it.  Three hard drives 
would not come back up.  Everyone except the sysadmins had a four-day 

Since then they've switched to using multiple, redundant hot-swappable 

I have a file server in the house that runs continuously.  It sits on an UPS.  
Everything else is shut down at night.
