  Man tar.  There are options in there for setting the level of the
backup, where 0 means do it/everything no matter, what, and then
1 is everything that's changed since the last 0, and 2 everything that's 
changed since both 0 and 1, etc... all the way up to 9.


  Put these in a cron and every night you can backup everything that's
changed since the night before.  Once a week, you can back up 
everything that's changed since the week before, etc...

  This will alow you to customize your backup regimin to fit with your
policy and resources.
