Full backup knoppix-style

Hi. I would like to do a full hard disk backup of a workstation that has a floppy, a CD-ROM and a DVD-RAM. Is there any option in the SuSE Live-CD or in the Knoppix CD to do a full backup of the hard disk using as backup media the DVD-RAM unit? -or- Is there any software available that's able to do a full backup of one or more write-mounted hard disk(s) using as backup media the DVD-RAM unit? thanks, ===== Riccardo G.
