The whole point of a clone with SuperDuper is that it is bootable. Of course
USB would presumably slow things down, maybe too much, others would know
better than me. But in the event of a catastrophe I fully expect to boot
from the external drive and then use the copy of SuperDuper there to clone
in the reverse direction.

I actually have 2 external drives both with bootable clones on them as an
insurance policy. I am unlikely to loose 3 drives all at once, and if an
external drive expires I still have a working bootable back up while I get a
new external drive.

I follow the recommended procedure from SuperDuper which is to clone in
preference to making a disk image. They point out that making a disk image
is slightly less reliable, and should be used only in special circumstances

That is my understanding of the SuperDuper information. Why not contact them
in order to clarify some of these issues. They are friendly folk.
