I note that it is possible to run clone jobs by using "Run = <jobname of 
current job> in the Job resource.

What I would like to do is make 2 tapes (Volumes) that are exact copies, 
but with only one catalog entry, used if either tape is restored.

1. Does cloning acheive this?

2. Can cloning be performed on a single drive?

The doc is a little unclear, stating:

"By using the cloning keywords (see below), you can backup the same data 
(or almost the same data) to two or more drives at the same time."

Then further down stating:

"Please note that all cloned jobs, as specified in the Run directives 
are submitted for running before the original job is run (while it is 
being initialized). This means that any clone job will actually start 
before the original job, and may even block the original job from 
starting until the original job finishes unless you allow multiple 
simultaneous jobs. Even if you set a lower priority on the clone job, if 
no other jobs are running, it will start before the original job."

The implication here is that the clone would run first on one volume and 
the tape could be changed to run the original job.

Regards,

Richard
