Exchange 2010 backups with NBU7.1.0.4

Created: 11 Jan 2013 | 5 comments

I am having an issue, one that doesn't seem to have an answer.

My office just upgraded from Windows 2003 to Windows 2008, and from Exchange 5.5 to Exchange 2010.

We have one main office in Washington DC and a satellite office in Denver Colo. Denver is our DR site, so one of the two mail servers functions as a redundant repository for the mail store DB's all of which are passive. The servers in the DC site are the DAG, CAS and MBX servers. The issue is that when I run the backup from the DC site, we hit the DAG server, in DC, first, which acts as the parent and calls child jobs for the MBX servers.

We have 3 MBX servers in DC and one in Denver. Since the backup hits the Denver server, and due to the fact that it runs across the WAN, it takes about 20 or so hours to backup, and has a through put of 100 to 300 Kbps.

Everything I am finding in reference to backing up Exchange 2010 says that it has to go through the DAG server, however this is a very big bandwidth hog when trying to backup the Denver MBX on the DC backup server. Is there some way to configure NBU to do a local backup of the MBX server without hitting the DC DAG? I am asking this as I am thinking that if the Denver backup server contacts the DC DAG, it will have the same throughput and bandwidth issue with the WAN.

Thank you

May be you can achive this by using the Preferred servers list in policy attributes...( I am not sure , its just  a wild guess)

Thanks Nagalla, tried that, from both ends, didn't work. I was abkle to stop the backup by denying access to the client by the DC backup server, but that also produces a status code 59 "Access denied" error. I am hoping to find a "clean" way to do this.

I don't understand what 'both ends' means?

... tried that, from both ends, ...

What is specified/selected in Policy Attributes in 'Microsoft Exchange Attributes' ?
What is selected in 'Database backup source'?
Have you tried 'Active copy only'?

with exchange 2010 servers are located by AD sites

Sync with AD and exchange guys on how this priority works.

Add all the Mailbox servers and choose either Active or Passive (As marianne stated enforce NBU to use Active only else fail the job rather than to continue over WAN and choke up network and also could impact transaction log clearance at Exchange if backups are failed in between!!!
