COMPUTE_IMAGE_ENTROPY for NetBackup primary servers

Use the COMPUTE_IMAGE_ENTROPY option to enable computation of entropy and file attributes in NetBackup that enhances cyber resiliency in NetBackup - Cohesity Alta™ View environment.

The entropy metric is used with the anomaly detection in Cohesity Alta View to help you detect potential malicious activity.

Table: COMPUTE_IMAGE_ENTROPY 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:

COMPUTE_IMAGE_ENTROPY = Value

You can specify one of the following values for the COMPUTE_IMAGE_ENTROPY option:

  • ALWAYS - Computation of entropy and file attributes is always enabled.

    This is the default value.

  • NEVER - Computation of entropy and file attributes is always disabled.

  • IF_MANAGED_BY_ALTA - Computation of entropy and file attributes is enabled if Cohesity Alta™ View manages the associated NetBackup primary server. If Cohesity Alta™ View does not manage the primary server, computation is disabled.

    Note:

    After the NetBackup primary server is registered with the Cohesity Alta View server, computation of entropy and file attributes starts within the next 24 hours with the new backup jobs.
