I don't think inline copy is what the OP is talking about.

My read is he wants to multiplex a tape backup with a duplication to
tape from a backup previously written to his disk storage.   

I don't think that is possible since bpbkup and bpduplicate are separate
processes.  I haven't attempted it and wouldn't think it advisable to do
it even if it were possible.

If you search this list someone did report backing up to a disk storage
unit
and tape at the same time, but you need to use in-line tape copy to do
this.
.. (and also the license for it)

As for as doing a bpduplicate job while a backup is running when the
only
drive available is being used, I have not tried doing it in that
scenario.
Also NetBackup 3.x?? Did you plan on upgrading anytime soon? :-)

I see what you want to do.

Regular backups -------> MPX1 -----> TAPE
                 \------> MPX2 -----> TAPE
                 /------> MPX3 -----> TAPE
Duplicate from /-------> MPX4 -----> TAPE
Disk

However, I have not tried this, anyone else on the list try this with
one one tape drive available?

He wants to multiplex a duplicate job from disk -> tape while other jobs
are running to that tape as well.

Justin.
