To forestall further answer of this kind:

=20

I am NOT looking for assistance in resolving the 52 error on the backup.
This problem would be caused if the issue had been any other issue that
caused a retry so wouldn't be restricted to a status 52 exit in any
event.

=20

I am NOT looking for "better" methods of doing a refresh.

=20

What IS being asked is if there is a way to prevent a single backup from
using the same tape on two different streams given that the backup in
question has multiple streams (e.g. please do not respond that I could
prevent it by doing the backup as a single stream).

Why don't you try to identify and repair what is causing the 52 errors?

=20

There are a few technotes and fixes for that specific error code, as it
is fairly common.

Subject: [Veritas-bu] Restricting tapes to a single stream

Is it possible to setup a policy in such a way that any stream will not
use a tape previously used within another stream of the same backup?

Background:

We run our Production DB backup using 3 streams.   This backup is used
for doing refreshes to test and training databases.   On occasion during
the original backup we'll see a status 52 forces one of the streams to
timeout and do a new try which is successful.  Unfortunately the new try
on that stream may occur after one of the other 2 streams has finished
with a tape so it grabs that tape for this stream.   This is OK but on
restore it won't even schedule the 3rd stream until after the stream
that originally used the tape has finished restoring so of course it
causes a long delay in refresh.   I didn't see a setting in the policy
definition so I'm wondering if there is a bp.conf or other setting that
would prevent the use of the same tape within two different streams of
the same backup?
