NetBackup for Microsoft Exchange backup fails with status code 72. The client type is incorrect in the configuration database.
The client type is incorrect in the configuration database
This problem can occur if the client is running Microsoft Exchange 2010 and the 'Perform snapshot backups' checkbox is not selected in the backup policy. Stream based backups (also known as legacy backups) are not supported by Microsoft in Exchange 2010 so, therefore, NetBackup does not support them either. The policy must be snapshot enabled.
Select the 'Perform snapshot backup' attribute in the policy.
