I'd start poking at the clone process with something like truss/strace (is it generally waiting on reads or writes?) and peek at the I/O rates on the drives (is the source drive at least delivering

Yes you can clone all the savesets on the volume. nsrclone -V volid Later, Joel Actually I do want to clone all of the savesets on this set of volumes (about 17 tapes). These are my monthly fulls and
