Troubleshooting Exchange jobs that use Granular Recovery Technology (GRT)
Note the following when you use NetBackup to perform backup or restore operations using Granular Recovery Technology:
Disable or uninstall QLogic SANSurfer software. It may conflict with the portmapper for Client for NFS.
Before you install NFS on the media server or client(s), look for the ONC/RPC Portmapper service. If it exists, stop it and disable it. Otherwise, the installation of NFS Services for Windows fails.
Exchange GRT operations can fail for the VM backup images that use display names that contain parenthesis. For example, a GRT live browse restore from the Backup, Archive, and Restore (BAR) interface fails with the following error:
database system error(Exchange 2010) The "Company" information for task objects is not restored.
A status 1 error may occur for a GRT-enabled backup if the granular processing operations failed to complete successfully. The job details under the Activity Monitor or error log should indicate if this failure is what caused the status 1. Look at the bpbkar debug log for more information.
NetBackup must be able to contact the proxy host (if applicable) or destination client.
If NetBackup cannot contact this client, then errors appear in the "Problems" or "All Log Entries" reports. The following error messages appear in the NetBackup error logs:
The granular proxy <clientname> for client <clientname> could not be contacted. Unexpected results may have occurred. See bprd debug log for more details.
Could not connect to <clientname> for virtual browse operation, errno=#, bpcd_status=#
For Exchange 2010, the following situations cause a restore to fail with a status 5:
Restores of a private mailbox item to a Public Folder
Restores of a Public Folder item to a private mailbox
In the
ncfgrelog, the following error appears:EWS Failed to get mailbox properties
If you attempt to restore an Exchange 2010 Public Folder item to a subfolder that has not been previously created, the restore fails with a status 5. The following error appears in the progress log:
MNR - error writing file: %1
Use one of the following workarounds to resolve this issue:
Retry the restore operation. NetBackup receives an error when it attempts to create the new subfolder. However, the subfolder is created. A second restore attempt to the same subfolder location is successful.
Create the subfolder manually before you attempt the restore. If the subfolder exists, the restore is successful.

nbfsdlogs from the media server. Use the Verbose setting carefully as thenbfsdlog can grow very large.
