A problem most of us are facing these days.

>/u01

When you say "split the filesystem", to me that means you're going to
reorganize how data is mounted on the client.  Somehow I don't think
that's what you're suggesting though.

If you mean that you're going to leave the client alone (/u01 will not
have a new, second mountpoint under it on /u01/oracle) but you're going
to modify the client "Saveset" parameter on the NetWorker server, then
the answer is "yes, NetWorker will back up all of /u01/oracle, *plus*
everything under /u01, which includes oracle).

What you need to do is create a special directive, on the server, named
something like

        clientname skip /u01/oracle

You'll essentially want to copy the "UNIX standard directives" and then
add a

<< /u01 >>
        +skip:  oracle

Apply the "clientname skip /u01/oracle" to your client, making sure that
this instance of the client uses the All saveset.

Next, create a second instance of the client.  The difference between
the two client instances:

             First client instance:              Second client instance:
             ======================              =======================
Directives:  clientname skip /u01/oracle         UNIX standard directives
Saveset:     All                                 /u01/oracle



Your first client backups up everything (All) but the custom directive
causes it to skip /u01/oracle.  The second client instance uses the UNIX
standard directives, but only looks in /u01/oracle.

Does this make sense?
