NetWorker 19.7 Snapshot Management Integration Guide

Basic backup workflow

In the basic backup workflow, data is transferred from the primary storage system to the Data Domain system. NetWorker NSM integration with ProtectPoint manages the data flow, but does not modify the data.

After creating the snapshot, RecoverPoint moves the snapshot to the Data Domain system. The primary storage system keeps track of the data that has changed since the last update to the Data Domain system, and only copies the changed data. Once all the data that is captured in the snapshot has been moved, the Data Domain system creates a static image of the data that reflects the application-consistent copy that is initially created on the primary storage system. The snapshot is then recorded by the NetWorker server.

The backup workflow consists of the following steps:

1. The file system or application backup is started using a NetWorker snapshot enabled policy or from the application host using NMDA or NMSAP integration.
   NOTE File system backups cannot be client initiated.
2. On the primary storage system, ProtectPoint creates a snapshot of the primary storage device.
3. RecoverPoint analyzes the data, and then copies the changed data to a Data Domain storage device.
4. The Data Domain system creates, and then stores a static-image of the snapshot.
5. NetWorker NSM creates a catalog record of the snapshot.
