Okay, mondo is great!  I believe that I installed it from Dag's yum 
repository, but I can't remember for sure.  If nothing else, the 
instructions on http://www.mondorescue.org were easy to follow, as I 
recall.

I'm backing up to DVD+RW media, as I mentioned before.  I run into a snag 
about every two weeks due to dvdrecord issues, but for the most part it's 
stable.  I'm posting my script below.  Please be gentle, it's the result 
of a lot of trial and error... :)
