I believe that clones are always single threaded. Therefore, I think what you
observed is the expected behavior.

Subject: [Networker] Fw: [Networker] Parallelism of "backup clone" pool devices?
Does anyone have any ideas about this?
>I know I'm missing something simple here ... I have a number of jobs
that
are clone jobs. So I have a tape library with 4 drives, all of which
are
defined as devices for a media pool that is a "backup clone" pool.
>I've noticed that it seems that each backup clone job will wait until
>there is a free tape drive, before writing. For example: I have JOB
1, 2,
3, 4, 5 - all are clone jobs, defined to use AFTD disk devices.
Assuming
that all finish writing to the AFTD devices at approximately the same
>time, JOB 1,2,3,4 will each use one of the 4 tape drives to write to,
and
JOB 5 will wait until a running job finishes, before writing to the
tape.
This is *not* the case with my other library, which has 4 drives, all
>defined as part of a media pool that is *not* a backup pool.
Consequently,
all 5 of those jobs will write to the 4 tape drives at once - i.e.,
one of
those jobs will be servicing 2 group
