I've talked about my backup script at meetings, but in essence what I do 
is build a directory tree filled with symbolic links to the files I want 
to back up (so the staging of the backup takes up almost no space), and 
then mkisofs on that directory.

I back up /home, /var/spool, Apache's document roots, and (here's the 
interesting one) all text files less than 40K.  By text file, I mean 
[ -T $File ] is true in Perl.  That will get you pretty much every single 
config file.  Who cares about backing up the rest of the OS?  Reinstall 
and restore your config files.

So far it all fits on one CD, but when it doesn't I'll just break the
apache stuff into a seperate ISO file.
