Issues with Backing up DAG Exchange 2010

 Hi All,

 

I'm coming over from ArcServe and have been trying to setup our Exchange Jobs in NVBU, but I'm struggling.

 

Our Exchange environment:

Location A:

 2 CAS Servers

 2 DB Servers

Location B:

  2 CAS Servers

  2 DB Servers

All 4 DB servers are in a DAG.

 

We have a NVBU server and library at each location.

The plan was to backup the non-active DBs in each location.  So, I setup a Virtual Client in each location comprised of the two DB servers at each location. 

When creating the Backup Selection Set I often get "Error: Failed to get connection to plugin".  I get this error often, but then randomly it'll work.  Although, when I check Access of the Virtual Client it passes.  Then when I check access and firewall access for each client (DB Servers) that's a member of the Virtual Client it passes as well.

 

EDIT: If I change the Virtual Client IP to the other DB server that's listed as it's member.  It'll work.  I'm able to expand the DAG and see the DBs to select what I want to backup.  But a few days later it'll stop working again and I'll have to flip to the other DB if I want to view the backup selection. 

The exchange backup jobs fail regularly as well. 

 

Any helpful hints or advice is greatly appreciated.

    Hi Andre,

    Thanks for the reply.

    Yes, it gets stuck for a minute or two before it errors out. Then if I switch the virtual client's ip to the other DB member it connects. But only for a few days and then it stops working and I'll swap it again.

    The DAG does have a cluster ip. What I'm doing (or trying to) is splitting up each location into two separate DAGs with each location consisting of 2 DB servers. That's probably my issue. It sounds like this is not possible. Instead I'll probably have to use the DAG cluster IP for the virtual client and then add all 4 DB servers from both locations as members of it.

    I'll raise a service request.
    Thanks.
