The following list describes the backup process when a media server deduplicates
the backups and the destination is a media server deduplication pool:
the backups and the destination is a media server deduplication 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 both a deduplication storage server and a load balancing
server. The storage server both deduplicates data and manages the storage.

■
The
bptm
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.
