[K12OSN] Server Backups

[Calvin Park, ADCS]

Something you might also look into:

http://backuppc.sourceforge.net/

I haven't had a chance to play with it much, but at first glance it
appears to be exactly what we're looking for here to do backups. It is
even supposed to do M$ Windows machines. Over the summer we're going to
be testing it here...but it might be worth it to check out. Just a
thought.
