Challenge

When the Veeam vPower NFS Service on the Mount Server used by the SureBackup job is set to use any account other than Local SystemThe default configuration is for the Veeam vPower NFS Service to "Log On As" the 'Local System' account., and that account is not a member of the Local Administrator user group, the SureBackup job will fail with errors similar to:

Error: Failed to call RPC function 'AddConnection': Access is denied. Failed to create registry key [SOFTWARE\VeeaM\Veeam NFS\Connections\04dda549-aeac-422e-9534-d06592fef6f6]. RPC: Failed AddConnection.
Note: The situation described in this article rarely happens because, by default, the Veeam vPower NFS Service is run using the 'Local System' account.

Cause

The access is denied error occurs because the account that the Veeam vPower NFS Service is set to use for 'Log On As' is not set to "Local System" and assigned account is not a member of the Local Administrators user group.

Solution

Review the Services (services.msc) running on the Veeam Backup Server and associated managed servers (proxies, repositories, etc.), and set the services to 'Log On As' Local System. This is the default configuration for all Veeam named services.

 

The only exception to using the Local System account for running the Veeam named services is when the VeeamBackup configuration database is located a SQL Server other than the Veeam Backup Server. In such a configuration, only the following services are modified to use a domain account to allow access to the configuration database on the remote SQL server:

  • Veeam Backup Server RESTful API Service
  • Veeam Backup Service
  • Veeam Broker Service
  • Veeam CDP Coordinator Service
  • Veeam Cloud Connect Service
  • Veeam Guest Catalog Service
