Data path

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.

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

■ The PureDisk plug-in retrieves a list of fingerprints from the last full backup

for the client from the NetBackup Deduplication Engine. The list is used as a

cache so the plug-in does not have to request each fingerprint from the engine.
