Note the following about NetBackup image duplication:

• When duplicating an image, specify a volume pool that is different from the volume pool of the original image. (Use the Setup Duplication Variables dialog of the NetBackup Administration Console.)

• If multiple duplication jobs are active simultaneously (such as duplication jobs for Vault), specify a different storage unit or volume pool for each job. Using different destinations may prevent media swapping among the duplication jobs.

• NetBackup provides the bpduplicate command to run and script duplication jobs. Veritas, however, recommends using either storage lifecycle policies or the Vault option when you implement duplication as part of a backup strategy.
