Hi,
No need to get confuse abt this 3rd active job. Actually the multiple backup works according to the below
When the backup is initiated thru manually/scheduled. The first active thread starts & this is responsible for initiating the copy 1 & copy 2 of the backup with two differnt volumepool tapes.
Once both the backup copies completed successfully , the initiator active job thread will also shows completed succesfully in the activity monitor.
If one copy fails & other copy completes successfully , the initiator thread will show status 1 " paritially successfull".
Hope it is clear for u , if you have any queries plz post it
Rgds
