The PureDisk plug-in performs file fingerprinting calculations.
The PureDisk plug-in sends only unique data segments to the storage server,
which writes the data to the media server deduplication pool.
Figure 9-5 shows the backup process of a client that deduplicates its own data.
The destination is a PureDisk storage pool. A description follows.

The following list describes the backup process for a deduplication client to a
media server deduplication pool:
The NetBackup Job Manager (nbjm) starts the Backup/Restore Manager (bpbrm)
on a media server.
The Backup / Restore Manager probes the client to determine if it is configured
and ready for deduplication.
If the client is ready, the Backup/Restore Manager starts the following
processes: The OpenStorage proxy server (nbostpxy) on the client and the data
moving processes (bpbkar on the client and bptm on the media server).
NetBackup uses the proxy plug-in on the media server to route control
information from bptm to nbostpxy.
The Backup/Archive Manager (bpbkar) generates the backup images and moves
them to the client nbostpxy process by shared memory.
