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 setting.

  See Maximum concurrent write drives setting.

• When using a storage lifecycle policy to create multiple copies, the number of destinations in the lifecycle cannot exceed the Maximum Backup Copies setting in the Global host properties. The lifecycle cannot be saved until the destinations are decreased, or until the Maximum Backup Copies setting is increased.

  See Maximum backup copies.

Multiple copy operations do not support the following:

• Third-party copies.

• NDMP storage units.

• Storage units that use a QIC (quarter-inch cartridge) drive type.

• The option to create multiple copies is not allowed for synthetic backups.
