Since XXCOPY views a drive just as a logical volume, it does not
make any distinction between D: as a physically different drive
and D: as a different partition which is on the same physical
drive of C: (To be more precise, XXCOPY does check to see if
a drive is a local drive or a remote (networked) drive but this
distinction is not relevant here).

So, when you run

XXCOPY C:\ D:\ /CLONE

It works equally well for a physically different drive and
for a different partition within the same drive.

Of course, when you try to create a bootable clone which would
be swapped as drive C:, you just can't do that in the case of
different partition.

However, you can do the following:

Say, you have two drives:

Drive 1 C: (primary partition) E: (extended partition)
Drive 2 D: (primary partition)

Run clone operations in two steps

XXCOPY C:\ E:\ /CLONE
XXCOPY E:\ D:\ /CLONE

Swap Drive 1 and Drive 2: and perform necessary steps to make
the new C: drive bootable (see the XXTB #10 article for detail).
Voila!!! The two-step clone should be as good as the normal
/CLONE operation.

So, the conclusion is that it is still worth doing the /CLONE
operation to the same-drive-different-partition destination.
When you really need to create a bootable disk out of a
backup partition, you may still do so with some extra work
(I'm not get into this here, but it is possible to restore
a bootable disk from the 2nd partition). Naturally, if hard
disk crashes (a real physical disaster), then, it is not as
safe as a backup to a physically different drive.

That is why it is best if you can use a physically different
drive for a backup (from both the extra safety point of view and
the convenience of disk swap for an immediate system restore).
