We're trying to set up multiple streams from a single large volume on one
of our clients, using the trick with having two client instances -- one
using Saveset "All" but with a server-side directive that skips certain
directories, and the other client instance that just backs up those
particular directories that are skipped via the All.  This method has
been discussed on the list before, for example see my post and Itzik
Meirson's follow-up from April 6th of 2004.

We have our special (server-side) directives set up (this is a NetWare

<< "ZW01VOL1:APPS" >>
       null: *
       null: *

We have one instance of the client defined, with Saveset All and those
directives being used.

We're trying to create a second instance of the client, with Saveset set
to just


As soon as I try put this second client in the same group as the first
one, I get an error from NetWorker:

       save set of All for client in group GroupName excludes
       any clients with the same name from the group.

I can see why NetWorker would want to at least warn about this -- if
you're using "All" with a client, in theory you're backing up everything
so having a second instance of the client in the same group seems like
a waste.  In practice, though, the directive controls whether anything
is really getting backed up by that client instance.  In our case, there
would be no significant overlap between the two clients, but NetWorker
isn't smart enough to realize this.

Is this just a limitation at version 6, or does this still happen at v7

For those of you that are using this trick to get multiple savestreams off
a big volume, have you found any way to have both instances of a client
in the same group, or are you forced to use a second group and run it at
the same time?
