Introduction
14 EBS with HP OpenView Storage Data Protector v5.1 Implementation Guide
Important Terms
■ Cell Manager—The Cell Manager is the main system in the cell. The Cell
Manager:
— Manages the cell from a central point
— Contains the Internal Database (IDB)
— Runs core Data Protector software
— Runs Session Managers that start and stop backup and restore sessions
and write session information to the IDB
■ Disk Agent—Install the Disk Agent on client systems you want to backup.
The Disk Agent reads or writes data from a disk on the system and sends or
receives data from the media agent. The Disk Agent is also installed on the
Cell Manager, allowing you to backup data on the Cell Manager, the Data
Protector configuration, and the IDB.
■ Media Agent—(For servers that have tape devices connected.) During a
backup session, the Media Agent receives data from the Disk Agent and sends
it to the device for writing to the medium. During a restore session, the Media
Agent locates data on the backup medium and sends it to the Disk Agent. The
Disk Agent then writes the data to the disk. The Media Agent also manages
the robotics control of a library.
■ Drive Servers—Client systems with connected backup devices and the
Media Agent installed.
■ Installation Server—The Installation Server holds a repository of the Data
Protector software packages for a specific architecture. The Cell Manager, by
default, is also an Installation Server.
Note: At least two Installation Servers are needed for mixed environments: one for
UNIX® systems and one for Windows systems.
