My guess is that if the drives (or partitions) are exactly the same
it would be a fast way because you could just do
	dd if=rawhd#1 of=rawhd#2 bs=1024x1024

or something like that to make an exact disk image (the bs
is for performance). Then you would take hd#2 off line (unmount?)
so that you couldn't accidently trash it.

On the other hand if hd#1 physically crashes while you are doing the
backup then you have lost hd#1 and hd#2 is inconsistent.

I'm thinking about dividing my fixed disk into partitions the same
size as a JAZ disk so I could do the same thing but remove the JAZ
disks; any comments?
