Vault - Duplication

I have duplicated the data to disk as per the below but now want to duplicate that data to new library.

https://vox.veritas.com/t5/NetBackup/NetBackup-Vault/m-p/833481#M227405

I have done the phase 1 and phase 2 import of the images and setup the vault duplication. I have setup the source to use the disk and destination to use 8 drives in the duplication tab of vault profie. But when the vault policy runs it tries to backup the data under 1 duplication job.

I have the retention of all these jobs on disk is 10 years. 

How can I run the duplication of disk data to tape to use 8 tape drives.

  • Could you share your vault profile configuration settings, specifically the 'Duplication' tab? I'd be interested to see how you have the destination configured.

      duplication tab setting below.

      source backup reside on disk is checked.

      Selected the primary check box, storage unit is tape with 8 drives( in the storage unit max concurrent drive is 8)

      write drives 8

      can NBU make multiple batches even the retention is same ? All the disk backups have same retention.

        Take a look at this technote, those 8 write drives you have specified will only be used when the following is met.

        When running vault duplication jobs; the number of tapes/tape drives used for the duplications depend on the following criteria:
        1. The value (i.e. number of write drives) specified from the Duplication (tab) > Destination > Write drives:
        2. The number of DIFFERENT retention values of the original (primary) copies of the images 'Chosen' to be duplicated.
        3. The policy configuration (in this case, the use of a load-balanced Storage Unit Group as the 'Destination > Policy Storage' for all primary backups)
