This may not be applicable, but I have Mint and it includes Backup Tool and it save data, preferences and software that is installed. If you want to make a installation cd there is APTonCD. Not sure if it is mint/ubuntu specific.
You'd have to ask someone more experienced but I remember something my friend told me about a dd command or a df -h command. Definitely don't remember and only think it works on debian/ubuntu/mint.

But, if I'm wanting a full image of the drive (so as to just plug the backup in and go in case of drive failure) don't I need the partition superblock and structure data as well? I know that the partition content can change during the copy, and with the data/processes on this drive/system that's OK. I guess I'd just like to be able to make a full, fully-bootable copy of a drive without having to shut down the machine that it's running on, if I can.
Oh, and I'd tried the copy command before with "cp /dev/hda /dev/hdb", but sometimes the result in /dev/hdb would work and would boot and sometimes it wouldn't, even after booting with a rescue disc and repairing anything bootloader-related. I was just curious if there's something that will do this type of backup on a more "consistent" basis.
