Backup sessions
What is a backup session?
A backup session, shown in Figure 7 on page 44, is a process that creates a copy
of data on storage media. It is started either interactively by an operator using the
Data Protector user interface, or unattended using the Data Protector Scheduler.
How does it work?
The Backup Session Manager process starts Media Agent(s) and Disk Agent(s),
controls the session, and stores generated messages to the IDB. Data is read by the
Disk Agent and sent to a Media Agent, which saves it to media.
