NetBackup status code: 168

Message: cannot overwrite media, data on it is protected

Explanation: A catalog backup was tried to a volume that cannot be overwritten because it contains data that by default NetBackup does not overwrite. (This data includes items such as tar, cpio, and ANSI.)

Recommended Action: Replace the volume with a new one or set the NetBackup ALLOW_MEDIA_OVERWRITE option to the appropriate value.
