Working with Replicas

In Data Protection Manager (DPM), a replica is a complete copy of protected data residing a single volume on the DPM server. A replica is created for each protected data source after it is added to its protection group. With data co-location, multiple data sources can have their replicas residing on the same replica volume.
As you monitor your data protection activities, you might need to modify synchronization frequency to better accommodate your data change activity, ensure that your replicas are consistent with their data sources, and delete replicas that are no longer needed. Having a replica that represents your live data provides the foundation for being able to both protect your data and recover your data.
