HP B6960-96035 - Manual (Page 42)

Systems to be backed up
Client systems you want to back up must have the Data Protector Disk Agent (DA),
also called Backup Agent, installed. To back up online database integrations, install
the Application Agent. In the rest of the manual, the term Disk Agent will be used for
both agents. The Disk Agent reads or writes data from a disk on the system and sends
or receives data from a Media Agent. The Disk Agent is also installed on the Cell
Manager, thus allowing you to back up data on the Cell Manager, the Data Protector
configuration, and the IDB.
Systems with backup devices
Client systems with connected backup devices must have a Data Protector Media
Agent (MA) installed. Such client systems are also called Drive Servers. A backup
device can be connected to any system and not only to the Cell Manager. A Media
Agent reads or writes data from or to media in the device and sends or receives data
from the Disk Agent.
Systems with a user interface
You can manage Data Protector from any system on the network on which the Data
Protector graphical user interface (GUI) is installed. Therefore, you can have the Cell
Manager system in a computer room while managing Data Protector from your
desktop system.
Installation Server
The Installation Server holds a repository of the Data Protector software packages
for a specific architecture. The Cell Manager is by default also an Installation Server.
At least two Installation Servers are needed for mixed environments: one for UNIX
systems and one for Windows systems.
Operations in the cell
The Data Protector Cell Manager controls backup and restore sessions, which perform
all the required actions for a backup or restore, respectively, as shown in
Figure
6 on page 43.
