About the Exchange credentials in the client host properties
The Exchange credentials in the client host properties indicate the account that has necessary permissions to perform Exchange restores. The permissions that are required depend on the Exchange version that you have.
Note the following:
In NetBackup 10.0 and later, credentials are stored in the Credential Management System (CMS). If you get an error that CMS is unable to process the credentials, ensure that the host name is configured in the host mappings settings.
To use GRT, configure the Exchange credentials on all granular clients.
Alternatively, you can configure the Exchange credentials only on the granular clients that perform restores. In this case, for the entire domain add "Exchange Servers" to the "View-Only Organization Management" role group. Perform this configuration in the Exchange Administration Center (EAC) or in Active Directory. See the following Microsoft article for more information:
The account that you configured for the must also have the right to "Replace a process level token."
For database restores from VMware backups, the Exchange credentials that you provide must have permissions to restore VM files.
If you want to restore from a VMware snapshot copy that was created with Replication Director, do the following:
If you specify the minimal NetBackup account for the Exchange credentials in the client host properties, NetBackup can back up only active copies of the Exchange databases. If you select in the Database backup source field when you create a policy, any backups fail. The failure occurs because the Microsoft Active Directory Service Interface does not provide a list of database copies for a minimal account.
