Is there any posibility in the near future for Backup Exec 2014 to support DAGs without cluster administrative access points ?

Could someone from Symantec please respond to this question and advise when support for IP less DAG's will be supported.

I don't want to be forced to use traditional DAG's !

A prompt response would be appreciated.

Kind Regards, Chris.

Please see the following TechNote document:

Browse or backup of Exchange DAG with no Cluster Administrative Access Point results in 'communication failure occurred' error.

Per Microsoft TechNet article

"Some third party applications connect to the cluster administrative access point to perform management tasks, such as backup or monitoring. If you do not use any third party applications that require a cluster administrative access point, and your DAG is running Exchange 2013 SP1 or later on Windows Server 2012 R2, then we recommend creating a DAG without an administrative access point. This simplifies DAG configuration, eliminates the need for one or more IP addresses, and reduces the attack surface of a DAG."

Backup Exec uses the cluster access point to resolve the IP address of the DAG.  To my knowledge, there is no other method for a third party applications to resolve the DAG name and connect directly to the DAG without a Cluster Access Point.

I'll e-mail this topic to the BE Product Management and try to obtain more information if we have plans to support this in the future - stay tuned.
