Figure 7 Backup session
A typical backup session is more complex than the one shown in Figure 7 on page 44. A number of Disk Agents read data from multiple disks in parallel and send data to one or more Media Agents. For more information on complex backup sessions, see Chapter 7 on page 219.
Restore sessions
What is a restore session?
A restore session, shown in Figure 8 on page 44, is a process that restores data from previous backups to a disk. The restore session is interactively started by an operator using the Data Protector user interface.
How does it work?
After you have selected the files to be restored from a previous backup, you invoke the actual restore. The Restore Session Manager process starts the needed Media Agent(s) and Disk Agent(s), controls the session, and stores messages in the IDB.
Data is read by a Media Agent and sent to the Disk Agent, which writes it to disks.
