Backup and Restore Functional Description
Figure 10. NetBackup Database Backup
3. Starts the actual backup by using bpcd to start the backup program, bpbkar.
If the database is on the master server, bpbackupdb starts the backup and archive
program on the master server. If the database is on a media server, bpbackupdb starts
the backup and archive program on the media server.
The bpbkar program transmits file information and the backup image to separate
bpbackupdb processes as shown on Figure 10.
◆ The original bpbackupdb process receives the backup image and sends it to the
backup device.
