About insecure communication with 8.0 and earlier hosts

NetBackup communicates insecurely with 8.0 or earlier hosts.

If you have NetBackup 8.0 or earlier hosts in your environment, you can allow insecure communication with them using the Enable insecure communication with 8.0 and earlier hosts option in the NetBackup Administration Console.

The option is available on the Security Management > Global Security Settings > Secure Communication tab.

This option also allows communication between NetBackup 8.1 or later primary server .

By default, insecure communication is enabled. However, for increased security, you should upgrade all hosts to the current version and disable communication with 8.0 and earlier hosts.

See Disabling insecure communication.

See About communication with 8.0 or earlier host in multiple NetBackup domains.

Note:

If you have configured Auto Image Replication, ensure the following before you disable insecure communication: The trusted primary server that you have specified for image replication is of the version that is later than NetBackup 8.0.

See About secure communication in NetBackup.
