Symantec 7 manual Deduplication to a PureDisk storage pool

Deduplication architecture 113

Media server deduplication process

■The PureDisk plug-in sends only unique data segments to the NetBackup Deduplication Engine on the storage server. The NetBackup Deduplication Engine writes the data to the media server deduplication pool.

Figure 9-3shows the backup process when a media server deduplicates the backups. The destination is a PureDisk storage pool. A description follows.

PureDisk deduplication pool

The following list describes the backup process when a media server deduplicates the backups and the destination is a PureDisk storage pool:

■The NetBackup Job Manager (nbjm) starts the Backup/Restore Manager (bpbrm) on a media server.

■The Backup/Restore Manager starts the bptm process on the media server and the bpbkar process on the client).

■The Backup/Archive Manager (bpbkar) generates the backup images and moves them to the media server bptm process.

This example shows two media servers.

■The bptm process moves the data to the PureDisk plug-in.

■The PureDisk plug-in performs file fingerprinting calculations.

■The PureDisk plug-in sends only unique data segments to the PureDisk storage pool.
