for Symantec NetBackup.

Symantec NetBackup Application Overview

Symantec NetBackup Enterprise Server is based on a client/server architecture, and comprises
several distinct components:
Master server: The master server (one per storage domain) manages data protection operations.
The NetBackup master server is responsible for containing the backup configurations and
policies, running the scheduler that initiates automated backups, maintaining catalogs that
track the location and contents of all backups, communicating with media servers to initiate
backup and restore processes, and providing both a command line interface and a graphical
user interface to administer NetBackup.
Enterprise Media Manager server: NetBackup Enterprise Server 6.0 introduced the Enterprise
Media Manager (EMM) server, which centrally manages Media Manager data that had
previously been distributed across multiple media servers. You can only have one EMM server
per storage domain. The master server can also be designated as the EMM server. The
NetBackup EMM server is responsible for managing a consolidated media and device database
for the NetBackup storage domain and maintaining run-time status information, NDMP
credentials, and a managed server list.
Media server: A media server can be any standalone server running NetBackup server software
that receives requests for backup and restore operations from the master server. (A master
server can also be configured as a media server.) A storage domain can contain multiple
media servers. Media servers communicate with the master server and EMM server to initiate
backup and restore operations on its attached storage devices, communicate with NetBackup
clients during a backup or restore operation, monitor the status of storage devices, and provide
robotic control.
Client: NetBackup clients are servers that have NetBackup client software installed. A client
performs backups through a media server (over the LAN if the media server is running a
separate server or directly as LAN-free backup if the media server is in the client server).
Storage Unit: A NetBackup storage unit is a storage device attached to a NetBackup server.
A storage unit consists of the media server and tape devices where NetBackup stores files
and data. If a storage unit contains two drives and one is busy, NetBackup can use the other
drive without administrator intervention. To send backups to a storage device, the administrator
must define storage units using the Device Configuration Wizard. For virtual library devices
such as VLS, the type of storage unit used is the "Media Manager storage unit." (Even though
VLS is using disk internally, it is seen by NetBackup as a tape library.)
