Quick recovery for server DR

After a disaster, the quick recovery feature enables you to restore assets and data that you replicated to a destination system at a remote site.

NOTE Quick recovery does not re-create the original backup environment and source system which protected the restored assets. Thus, quick recovery is not a substitute for a server DR restore. To continue backing up the restored assets at the remote site, add the restored assets to a protection policy on the destination system.

Quick recovery is supported for the protected assets of the following PowerProtect Data Manager asset sources:

  • Virtual machines
  • Kubernetes
  • File system
  • NAS

Quick recovery sends metadata from the source system to the destination system, following the flow of backup copies. This metadata makes the replication destination aware of the copies and enables the recovery view. You can recover your workloads at the remote site before you have the opportunity to restore the source PowerProtect Data Manager system.

For example, the following figures show two sites that are named A and B, with independent PowerProtect Data Manager and DD systems for protection storage. Each site contains unique assets. Figure Figure 1 shows the initial configuration with both sites replicating copies to each other. Figure Figure 2 shows the aftermath, with site A down. The site A assets have been restored with quick recovery into the site B environment from the replicated copies.

PowerProtect Data Manager supports quick recovery for alternate topologies. You can configure quick recovery for one-to-many and many-to-one replication. For example, the following figure shows a source PowerProtect Data Manager replicating to a standby DD system with its own PowerProtect Data Manager, all in the same data center. If the source system fails, the quick recovery feature ensures that you can still restore from those replicated copies before you restore the source.

The following topics explain the prerequisites, how to configure PowerProtect Data Manager to support quick recovery, and how to use the recovery view to restore assets.
