the '/' in question is me telling the tar file to archive or tar the 
root directory, not root home, but the root directory.  sorry for the 
confusion, the mail client must have chopped the line off!
i'll check out the afio thing, and i 'think' i fixed the TAR entry, i 
changed it to:

#!/bin/bash
#backup of system information
tar -zcvpf /BloomCounty/BillTCat/`date +'%Y-%m-%d'`_fc4backup.tar.gz 
--label="Fedora Core 4 Full Backup" --exclude=mnt --exclude=proc 
--exclude=var/spool/squid --exclude=BloomCounty --exclude=*.iso 
--exclude=*.rpm --exclude-caches /
#backup of my personal files for college
tar -zcvpf /BloomCounty/BillTCat/`date +'%Y-%m-%d'`_SEMo_U.tar.gz 
--exclude-caches --label="SEMo_U Full Backup" /BloomCounty/Binkley/
