REQUIRED_NETWORK option for NetBackup servers

The REQUIRED_NETWORK option specifies the required route for backup traffic in an environment where the network traffic is segregated.

For example, an environment can contain a production network at 145.21.14.0 and a backup network at 192.132.28.0.

Table: REQUIRED_NETWORK information

Usage

Description

Where to use

On NetBackup primary servers.

How to use

Use the nbgetconfig and the nbsetconfig commands to view, add, or change the option.

For information about these commands, see the NetBackup Commands Reference Guide.

Use the following format:

REQUIRED_NETWORK = IP_address

This entry should appear only once in the configuration file.

Note:

If the variable is set and the network is not available, all connections fail and no backups are performed.

Example

The required network is set to 192.132.28.0 in the following example:

REQUIRED_NETWORK = 192.132.28.0

Equivalent NetBackup web UI property
