To improve flexibility for external workflows and reduce infrastructure costs,
PowerProtect Data Manager supports sharing
protection storage across multiple
objectives.
To service workflows outside of
PowerProtect Data Manager, 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 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.
NOTE
Because
PowerProtect Data Manager is unaware of external workflows, the UI issues a warning when you configure a policy with multiple
objectives that share the same
protection storage system. This configuration is uncommon, so verify the storage targets and the use case before you continue.
The UI also issues a warning where the selected storage unit is the source for any MTree replication workflow. This workflow may belong to another application. Verify the storage targets before you continue. These notifications require
DDOS 7.7 or later.
