I can only agree that O'Reilly books are well worth the price of
admission.  

As for the backup schemes / plans (which I can only assume are in that
book, as I've not personally read it yet), I favor a 3-2-1 setup.

 - 3 copies (original, backup, backup of the backup)
 - 2 mediums (HDD & something else - right now optical ... though I
   really need to change that)
 - 1 offiite

Don't forget that "if you don't have a tested backup, you don't have
a backup."

Currently, the system here is

 - every PC has a cronjob backing up $HOME to a central "server" (read -
   repurposed PC with decent WD drives), just an rsync script that runs
   daily.
 - /path/to/backups/$user/Documents/ is tar'd weekly and burned to disc.
 - discs are copied, and taken to parents' place.  "Rolling Updates" are
   performed there (as the CD case / binder thing (see: [1]) is already
   full, take oldest set of discs, replace with the newest, repeat til
   full again, then start over at the beginning).
