PLAC (portable linux auditing CD, a mini-bootable distro I've ranted about before on the list) also has some sort of entire-disk duplication built into it; it is forensics-quality, so I'm sure they've just made a wrapper around dd, maybe with some checksumming (does dd do this on its own?) to verify... it might be an easy solution, if you can boot a cd on your system and have 32megs of ram or moe (most non-ancient systems will work). PLAC mounts the booted system's own drive in read-only -- you can manually override this, or do the PLAC standard of copying to a network resource (LAN or WAN).
On another note, I don't know if RH8 has given you any problems, but I've known it to have a few (maybe the updates fixed those?), but I'd be happy to lend you some v9 CD's to upgrade with, lemme know...
