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
