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.
