Assuming ABC001 is a volume, yes.  The behavior of what happens with
savesets that span volumes depends on the version of networker.

Older versions will clone the saveset (possibly requiring other source
volumes) regardless of how much is on the volume.

Newer versions will only clone the saveset if it begins on the volume.
(That way if you clone multiple volumes, you don't end up cloning the
same saveset multiple times).

I can't recall which version made the change.

I don't think it would take much longer, but it may depend on whether
the source volumes are multiplexed.

You can also provide nsrclone with multiple savesets on the same line.
That method and volume clones should keep the multiplex on the clone.
If you do lots of individual nsrclones (one saveset per), then you'll
demultiplex them.  That can take a long time in some cases (but may be
something you want to do).
