Hi
I am facing a problem while backing up exchange GRT using nbu 7.0.1.
I have 6 databses to back up which i have configured policy to backup from passive copy to back up.
All the Permissions and NFS are configured according to admin guide.
My DB1 & DB2 GRT are failing but for rest of the the DB's 3 4 5 6 the GRT is sucessfull. The below is what DB1 gives when it jobs colmpleted with status 1. i presume there is some permissions issue with the Logs folder drive with DB1 & DB2 as the rest DB's are successful. ANY IDEA.

Hi Rizwan,
I woudl suggest running that backup with out GRT first. The error is related to the logs in exchange and most probably due to the logs not being in sync (replicated) with the active copy.
Can you post your policy please. bppllist "policy name" -U
How is your dag configured, how many nodes, active, passive etc.

The backup without GRt is completing successful and also commit the logs as well.
The DAG is running between two nodes present at the same datacentre.
The DB1 policy is as follows.

Hi Rizwan,
Unfortunately I can only suggest some logical troubleshooting steps.
Are the the logs for each DB kept in their own log folders/drives? If so, verify the permissions on the folders and on the databases (for the Netbackup account).
Does the GRT backup work if you point it to the active copy? Try it if possible.
Finally, try and use Microsoft Exchange Database Availability Groups:\ as the directive for the policy instead of individual DB specifications. I've had an issue at client where the directive caused a problem and it was also related to the "logs error". Strangely enough in that case we had to split the DAG into policies listing the DBs (oppposite to what I've suggested for you).
Maybe this way you can pin point the issue.
Hope that helps.

Dear Riaan,
The logs are on diffrent diffrent drive and each DB has seperate log drives can you specify the right required so taht I can change it and test the backup after enabling those rights on logs drive and on DB folder itself as well.
As I cannot a perform a backup on active copy.
Regards
Rizwan

We are facing the same problem with two-node Exchange 2010 DAG. Netbackup master/media on Windows 2008 R2, version 7.0.1.
I checked Exchange-logs and during GRT enabled backups - at the same moment when Netbackup reports "WRN - Unable to get the mount timeout value" - Exchange reports:
"Windows(R) Lightweight Directory Access Protocol (LDAP) failed a request to connect to Active Directory Domain Services(R) for Windows user <OURDOMAIN\ourbackupuser>.Without the corresponding UNIX identity of the Windows user, the user cannot access Network File System (NFS) shared resources. Verify that the Windows user is in Active Directory Domain Services and has access permissions."
Without GRT enabled, no NFS related errors are reported to Exchange events.

I got GRT working by adding empty file "No.Restrictions" to <netbackup install dir>\db\altnames . Notice that this file allows any NBU client to browse any other client's backup-images on master. So I investigated this a bit more and noticed that it is enoug if you add emtpy file named "dag-cluster-node-name" (all cluster nodes) into that directory.
Do you have separate network interface for backups in DAG-nodes?
02-28-2011 05:25 AM
Kindly let me know on which server i have to cretae this file and wjhat will be the name of the file and what i should put inside it.
my dag name is mtn-mail-dag nodes are ac1-srv-embx01 & 02.
We are using seperate interfaces.

Rizwan, can you tell me what happened?

Sorry for the delay... you should put those files on master server.

I had simillar issue. The issue was resolved after resolving replication issues and restart of both DAG nodes.
