Anytime someone mentions backups, I have a knee-jerk reaction to mention
backuppc because it is simple and will likely do anything you need.  Docs are
here: http://backuppc.sourceforge.net/ It is packaged in epel.  It can use rsync
 (with/without ssh), smb, or tar for the backup transport.  Generally for
anything remote, you'll want rsync, and you'll want it badly enough to set it up
even on windows targets - which is not all that difficult.
