To create multiple copies, the following criteria must be met:

• The backup destinations must share the same media server with sufficient resources available for each copy.

• The storage units that are used for multiple copies must be configured to allow a sufficient number of concurrent jobs to support the concurrent copies. The pertinent storage unit settings are Maximum concurrent jobs and Maximum concurrent write drives.

  See Maximum concurrent jobs storage unit setting.

  See Maximum concurrent write drives storage unit setting.

Multiple copy operations do not support the following:

• NDMP storage units

• Synthetic backups

• Storage lifecycle policies

  Storage lifecycle policies offer their own method to create multiple copies.

  See About writing multiple copies using a storage lifecycle policy.
