To add to Terry Clayton's response:

On a file-type device, savesets are stored in a non-multiplexed way, even if
multiple savesets are concurrently written to the device.  So when you clone
from a file-type device, the output will be non-multiplexed, regardless of
whether you issue a single nsrclone with multiple SSIDs or multiple
nsrclones each having a single SSID.

Or, for those who are more visually oriented:

If data is written to a file-type device as if it were being multiplexed:

        SSID1 SSID2 SSID1 SSID3 SSID2 SSID3 SSID1

It is actually stored as separate savesets:

        SSID1
        SSID2
        SSID3

So when you clone these savesets to tape using EITHER

        nsrclone SSID1 SSID2 SSID3
                or
        nsrclone SSID1
        nsrclone SSID2
        nsrclone SSID3

The output tape will be non-multiplexed:

        SSID1 SSID2 SSID3

Staging behaves the same way as cloning.

Hi George


"Probably the reason why no conclusive information has been obtained from
Legato is because there are probably very few people there who truly
understand the code and how it works on a lower level."

Actually, Legato's Terry Clayton answered the basic question on 4/23 (see
http://listmail.temple.edu/scripts/wa.exe?A2=ind0304&L=networker&P=R28381&D=
0&I=-3&X=6CBF3C5E4D55446EDE&Y=lemons_terry AT emc DOT com in the archives).  His
answer is that it depends on how you invoke the clone:

nsrclone SSID1, SSID2, SSID3 will not de-multiplex

nsrclone SSID1
nsrclone SSID2
nsrclone SSID3  will de-multiplex.
