trying to get more multiplexing with SAP backups
We generally run a multiplex level of 4 to 8 on our Standard backups. I'd like to get up to that level with SAP backups.
This is my understanding of how SAP interacts with Netbackup (without Rman in this case, but I think its similar):
The DBA's generally have me define the backup policies with multiplex of 2.
In the init<SID>.utl file they will then (for example) specify a setting of "DRIVES 4". So 4 Netbackup jobs will get submitted and the Multiplexing setting will then cause two drives to be used (4 / 2).
But no other jobs running will then multiplex with this backup. And I then have sets of SAP backup jobs queue up because each wants their own one or two drives.
What do most shops do with SAP and Multiplexing? Can I get more Multiplxing across SAP backups?
