The PowerProtect Data Manager Appliance system protection service enables the protection of the system’s persistent data from catastrophic loss by creating a series of Server DR backups. PowerProtect Data Manager Appliance supports replication of Server DR backups to another PowerProtect Data Manager Appliance and to an external Data Domain System. From a system recovery perspective, only one target system can be configured or added. From a PLC perspective, the appliance supports various topologies, as outlined in Quick recovery.
Note: Create a separate PLC for each asset to optimize replication topologies (Fan-in, Fan-out) at an asset level.
System recovery creates point-in-time snapshots of the PowerProtect Data Manager Appliance server in protection storage. During a DR activity, recover the server from protection storage and then restore protected assets.
Only one backup target and one replication target are supported at a time (1:1).
Note: When you specify a new PowerProtect Data Manager Appliance or external Data Domain System as the target, you override the existing selection.
Quick recovery makes a remote PowerProtect Data Manager Appliance replication destination aware of replicated backups and enables the recovery view. During a DR activity, you can restore assets from these replicated backups at the destination without recovering the source server.
The following figure shows the bi-directional replication topology:
Quick recovery supports the following workloads.
Note: Backup copies that have been moved to Cloud Tier cannot be used for quick recovery. To use these backup copies, recall them from Cloud Tier.
Cloud DR enables you to restore to a DR site in a supported public cloud environment. During a DR activity, restore virtual machines to a cloud DR server and recover those workloads in the cloud.
Currently, only one cloud DR site can be configured with PowerProtect Data Manager Appliance (1:1).
Note: For more information about server DR and configuration, see the PowerProtect Data Manager Appliance DM5500 5.16.0.0 Administration Guide.
