Duplicating many Oracle backups is causing lots of media to be used. (80363)

Title: Duplicating many Oracle backups is causing lots of media to be used.
Date: Dec 10
Product & Version: NetVault All
OS Version: All
Module & Version: N/A
Application version: N/A


Symptoms:
When duplicating many Oracle backup jobs, NetVault copies only some megabytes on each media and therefore the Backup uses a lot more media than before.

Here is the solution to the problem of many tapes being used for the Oracle RMAN duplication:

1. Please edit the affected jobs.
2. Select the Advanced Options tab and select the Modify tick box at the bottom of that window. Then select the Modify button.
3. Within the "Secondary Copy" section, select the "Allow Streams to Share Media" option.
4. Save and re-submit the job and / or set.


The reason for this problem is that the Oracle RMAN backup consists of multiple objects and each with their own dedicated stream.
