It depends on how you do it but if you set NetWorker to automatically
clone tape to tape the clone will NOT be demultiplexed.  If you clone
manually one save set at a time then you will have a demultiplexed
clone.

One other comment on the discussion about faster restoring from a
demultiplexed clone.  While it would be faster I wonder if it's really
that much faster.  I'd love to see some data on that.  I suspect it's
more like you might save 5 minutes or so on a 2 hour restore.  For me
that sort of time saving wouldn't be worth the effort to demultiplex the
clone.  I guess the more streams you have in the multiplex the better
your time saving would be from demultiplexing (more tape between each
piece of the particular stream you are restoring increasing the seek
time to find the next piece) so there would be a point where it becomes
worthwhile but doubt our parallelism of 12 reaches that point.

So let me get this straight, cloning one saveset off of a tape to
another
clone tape will demultiplex the saveset.
