The shunt utilites: shunt, exactly, and flyisofs, were originally written for burning multi-set CDROM backups using mkiosfs and cdrecord.
Here is an example of using shunt with flyisofs to make offsite copies of compressed backups onto a series of DVD+RW discs: shunt -c 'dump -0af - /path/to/backups' + \ 'flyisofs mbc=2295104 fbc=2000000 | growisofs -Z \ /dev/rcd0c=/dev/fd/0' "$ <utility> -h" provides minimal usage information.
