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

Hi,

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.

http://www.symantec.com/docs/TECH218366

Per Microsoft TechNet article http://technet.microsoft.com/en-us/library/dd979799(v=exchg.150).aspx:

"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.

There is no way to convert an IP Less DAG to an IP DAG. Microsoft has clarified here under the topic “converting an Existing DAG”. So if you are willing to use Backup Exec which I agree has been an exchange friendly backup software from years then you need to break the current DAG then form a new cluster and add the database.

any update about this ... if IP less DAG still not supported by BE, can we do a classical backup on one of the excange DAG member.

Based on the feedback in this thread and other information provided by Microsoft, we have decided to support IP-less DAG. Support will be provided in an upcoming release.

Hello,
 
Product Management is looking for Backup Exec customers who are managing Exchange DAG’s to participate in an upcoming sprint development cycle.  That means we would host a call with those selected on a bi-weekly basis for approximately 30-45 min.
 
Topics:
Managing Exchange IP Based DAG’s today
Managing Exchange IP-Less DAG’s today
Managing Exchange DAG’s across a forest and over the WAN.
 
Please reach out to me directly if you have an interest and we can make sure we have an NDA in place.
 
Thank you and GO VERITAS!
Skip St. Pierre
Sr Product Manager
CCSP, VTSP
