Overview of security certificates in NetBackup

NetBackup uses security certificates to authenticate NetBackup hosts. The security certificates conform to the X.509 Public Key Infrastructure (PKI) standard. A primary server acts as the Certificate Authority (CA) and issues digital certificates to hosts.

Any security certificates that were generated before NetBackup 8.0 are referred to as host name-based certificates. NetBackup is in the process of replacing these older certificates with newer host ID-based certificates. The transition will be completed in future releases and the use of host name-based certificates will be eliminated.

However, the transition is on-going and NetBackup continues to require the older host name-based certificates for some operations. The following table lists various operations where host name-based certificate is required.

Note:

All NetBackup 8.1 hosts must have a host ID-based certificate.

Table: Host name-based certificate requirements for NetBackup 8.1 hosts

Operation or component

Type of certificate required

NetBackup Access Control (NBAC)

If NBAC is enabled on a NetBackup host, the host requires a host name-based certificate. These are automatically deployed when NBAC is enabled.

Enhanced Auditing operations

Enhanced Auditing operations require that the hosts have host name-based certificates.

See Deploying host name-based certificates.

Cloud storage

This is applicable to NetBackup media server versions 8.0 to 8.1.2 only.

The NetBackup CloudStore Service Container requires that the host name-based certificate be installed on the media server. If the certificate is not installed, the Service Container cannot start.

See Deploying host name-based certificates.

For more information, see the NetBackup Cloud Administrator's Guide.
