The other problem I had was exponential growth of the backups - the backups were taking backups of the backups!
You need to assign an exclude path if you put the backups in the /home or /var directories as I initially tried. You can't just put them in root either!
Edit the config file: /usr/local/tbackup/paths.cfg
tar_path /bin/tarWell at least I've got the root of that problem now!
exclude_path /boot /dev /initrd /lib /misc /mnt /opt /proc /sbin /tmp /rbackup
