Step 5. Specify Mount Server Settings

At the Mount Server step of the wizard, specify settings for the mount server that you plan to use for restore operations and configure a helper appliance. The helper appliance is a Windows-based or Linux-based virtual or physical server, added to the backup infrastructure, that Veeam Backup & Replication uses to perform a health check of backup files and apply retention to unstructured data backup files. For more information, see Health Check for Object Storage Repositories and Helper Appliance in Unstructured Data Backup.


Consider the following:

  • If you do not configure a helper appliance, Veeam Backup & Replication will use local resources to perform the health check and apply retention to NAS backup files. It will consume more cloud resources and can result in additional costs.

Specifying Mount Server Settings

To specify the mount server settings, do the following:

  1. From the Mount Server drop-down list, select a server that you want to use as a mount server. Veeam Backup & Replication uses this server during restore operations to mount VM disks directly from objects located in object storage repositories. For more information, see Mount Server.

The Mount Server list contains only Microsoft Windows servers that are added to the backup infrastructure. If the server is not added to the backup infrastructure yet, click Add New on the right to open the New Windows Server wizard. For more information, see Adding Microsoft Windows Servers.

  1. In the Instant recovery write cache folder field, specify a folder to keep cache that is created during mount operations.
  2. Select the Enable vPower NFS service on the mount server check box to allow the Veeam vPower NFS Service access the object storage repository. Veeam Backup & Replication will enable the Veeam vPower NFS Service on the necessary mount server. For more information, see Veeam vPower NFS Service.
  3. Click Ports to customize network ports used by the Veeam vPower NFS Service. In the vPower NFS Port Settings window, specify the following settings:
  • Next to the Mount Port section, specify the port that the Veeam vPower NFS Service will use to mount the vPower NFS datastore to the ESXi host.
  • Next to the vPower NFS port section, specify the port that the Veeam vPower NFS Service will use to connect to the target NFS share.

For information on ports used by default, see Ports.


  1. To specify the helper appliance settings, click Configure. From the Managed server drop-down list, select a server that you want to use as the helper appliance.


Do not enable Microsoft Windows NFS services on the machine where you install the Veeam vPower NFS Service. If Microsoft NFS services and Veeam vPower NFS Service are enabled on the same machine, both services may fail to work correctly.
