20 EMC NetWorker Release 8.1 SP1 Installation Guide
Introduction
Table 1 on page 20 summarizes the different databases a NetWorker server uses to
manage a datazone.
NetWorker Management Console server
The NetWorker Management Console (NMC) server or Console server, is a Java-based web
application and database server that provides centralized:
◆ Management of multiple NetWorker servers across multiple datazones.
◆ Monitoring of multiple NetWorker servers across multiple datazones.
◆ Reporting for multiple NetWorker servers across multiple datazones.
Table 1 NetWorker server database functions
Database Function
Client File Index
(CFI)
Tracks the files that belong to a save set. There is one client file
index for each configured NetWorker client.
The client file indexes can grow to become prohibitively large over
time and negatively impact backup performance.
Media database
(mm)
Tracks:
• The volume name.
• The location of each save set fragment on the physical media
(file number/file record).
• The backup dates of the save sets on the volume.
• The filesystems in each save set.
Note: There is only one media database per server.
The media database can grow to become prohibitively large over
time and negatively impact backup performance.
Jobs (jobsdb) Stores for a limited amount of time, information about NetWorker
job operations, for example:
• Scheduled and queued backup and recovery operations.
• Real-time backup and restore related activities.
• All Console server communication.
Recovery operations do not require the data stored in the jobsdb
database.
Resource
(resdb)
Stores the configuration information for a NetWorker server, for
example:
• NetWorker client backup configurations.
• Schedule recover configurations.
• Pool configurations.
• Device configurations.
Client push
(cpdb)
Stores configuration information for the Client push application.
nsrla Stores configuration information for the NetWorker nsrexecd
service.
