III.B. How to Decrease The Number of Simultaneous Duplication Jobs That Will be Activated

As seen in Example 3 above, it is possible for a DSSU relocation job to create enough duplication jobs to occupy all the tape drives in a tape library. It is possible to configure NetBackup to activate a smaller number of duplication jobs for a DSSU relocation job.

To do this, the administrator should define an additional media manager storage unit that is configured with aMax Concurrent Write Drives setting that is equal to the maximum number of drives that should be used at one time for DSSU relocation. The customer's DSSU configuration should then be modified to specify this new storage unit as the FSU. (see section III.C. below for an example)

Hi Guys

We'd like to stage from disk to tape during the day after backups are completed and the system is quiet. However when this happens , all tapes drives in the group are used. which limits the ability to perform restores. I cant see any where in the diskstorage unit config that limits the number of drives so we can leave 1 or 2 free for restores

regards

Mark W
