Symantec NETBACKUP 7 - Manual (Page 113)

■ 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 9-3 shows 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.
