Hi,
I've been having some trouble getting My Exchange 2010 SP1 backups working. I'm using Symantec Backup Exec 2010 R3. Both servers are 2008 R2 64 bit.
Exchange is setup in a DAG connected by a high speed WAN link. Backup Exec is set to backup the active (local) copy on the primary site. Exchange shows mailbox databases are healthy and mounted. There are several mailboxes within my DAG, but 1 consistently fails to backup (MailDB)
The message on Exchange I get in the event logs are (The previous mail backup attempt occurred 24hrs ago):
Symantec Backup Exec displays the error message "failure querying the writer status", which according to Symantec support is a general error message.
VSS Admin List Writers on Exchange shows 0 errors and only uses the default Microsoft VSS writers.
My first attempt will be to try backing up the passive copy of MailDB at the secondary site.
Has anyone come across this before? Any advice much appreciated.
Thanks

Wouldn't simply backing up the passive copy of the DAG at the secondary site achieve the same result?

Trying to backup the passive copy at secondary site failed with a failure querying writer status.
Other DBs backup fine, just this 1 fails.
I've came across the article below which may help, but first want to ask Symantec for their advice:

Unfortunately an Exchange reboot didn't resolve this issue, I've moved the faulting database backups over to the 2nd data center and will back up the passive copy.
After the reboot of Exchange, I'm back at square one:

Hi,
try the following:
1. Follow the TN below to reregister the VSS *.dlls.

2. Restart the server, or follow the MS TN below:

Try the backup again.
Thanks!

Hi Craig,
I think that could be my last option. I'm reticent to to do that, as I don't know what the impact will be in our environment. The article mentions that the VSS disables DFSR replication:
Do not follow this procedure to re-register the VSS writers if the customer is using DFSR replication. It will stop the replication process
Im not sure if any part of DAG replication uses DFSR, in which case, the option would not work(?)

That's more a Microsoft question to ask on their forums.
From a VSS perspective, every backup software now basically uses VSS, including Server 2008's built-in utility. If VSS doesn't work properly, chances are good your backups won't either.

Yep agree with Craig, you can try what http://support.microsoft.com/kb/930800 suggest:
Use this method if the event ID 9840 that was logged on the Exchange 2007 server contained error code 2403.
To dismount all databases in the storage group, follow these steps:
If this method does not resolve the problem, try method 2.
Use this method if the event ID 9840 that was logged on the Exchange 2007 server contained error code 1293. Use this method if Event ID 9607 was logged on Exchange 2003. Additionally, use this method if method 1 did not resolve the problem.
To restart the Microsoft Exchange Information Store service, follow these steps:
Looks like something from MS side , ¿Do you have the events id mentioned in that document on all the Exchange server?
