Media server deduplication pool

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.
