I hate to mention this in a Windows hating community, but the Windows Server ASR backup works like a charm. You can always boot with a Windows CD, and then all you need is the ASR floppy that has your disk configuration, and your backup media, whether tape or external hard disk.
Not bad if it works. I've never seen anyone successfully restore a windows box though without having tons of issues with it later (if it was successful at all) though.
