I am seeking a complete system backup/bare metal restore utility that would do the following:

* Bootable LiveCD that boots with a backup/restore tool that can interactively backup the HDs in the machine to DVDs (multiple DVDs if necessary).
* Boot from it's own CD/DVD media (ideally, though not critical)
* Backup to DVD (multiple DVDs if necessary) my Linux (FC5/FC6) server
* It would be awesome if this utility could backup my WinXP machines as well as Linux

Does Knoppix do this? If not, could it? If Knoppix isn't the answer, can anyone recommend a very reliable backup to DVD/bare metal restore solution?

The LiveCD could be ANY OS, if it will do what I seek.
