Dell PowerProtect Data Manager Appliance 5.13.0.0 Administrator Guide for DM5500

Replication to shared Protection Storage

To improve flexibility for external workflows and reduce infrastructure costs, PowerProtect Data Manager Appliance supports sharing Protection Storage across multiple objectives.

To service workflows outside of PowerProtect Data Manager Appliance, you may require different retention periods for different replicas. Since retention periods are set at the objective level, configuring different retention periods requires additional replication objectives.

Under most circumstances, additional replication objectives target storage units that reside on different protection storage systems. Replicating to separate Protection Storage provides additional data availability.

To support external workflows without requiring separate protection storage systems for each additional objective, PowerProtect Data Manager Appliance supports targeting different storage units on the same protection storage system. To further reduce costs, you can target the same protection storage system where the primary backup resides. In this case, the external workflow provides the additional data safety. When replicating an extended retention, select a storage unit that also holds a replica of the primary backup.
