My ideal has been NetApp style snapshots.  Every 15 minutes, hour, day,
week, month.  Keep them until the next higher one or as space allows.
OpenSolaris does this for free, now.  It typically adds 10% to the storage.

That takes care of 90% of restores for users.  I had 225G for 200 users
1996-2000 and never had to restore from tape.

Then, take periodic archives (weekly, monthly?) to other media until it
rots.  Tape, DVD, drives, etc.  Because hardware fails and so does media.

Anyone got a good recomendation for archiving (with indexing) to
DVD/Tape/idle USB drives?
