Connecting to External NFS Shares via Acronis Backup Gateway
------------------------------------------------------------

.. note:: 

   #. Virtuozzo Infrastructure Platform does not provide data redundancy on top of NFS volumes. Depending on the implementation, NFS shares may use their own hardware or software redundancy.
   #. In the current version of Virtuozzo Infrastructure Platform, only one cluster node may store backups on an NFS volume.

Before you proceed, make sure that:

#. The NFS share has enough space for backups;
#. Each NFS export is used by only one gateway. In particular, do not configure two Virtuozzo Infrastructure Platform installations to use the same NFS export for backup storage.

To connect Acronis Backup Cloud or Acronis Backup Advanced to an external NFS share via Acronis Backup Gateway, do the following:

#. Make sure that the Acronis Backup Gateway network role is assigned on the node that will run the gateway service.

#. On the **STORAGE SERVICES** > **Backup** > **NODES** screen, select the checkbox next to the only node in the cluster.

#. Click **Create Gateway** and **Network File System**.

#. Make sure the network interface with the assigned Acronis Backup Gateway network role is selected. The gateway service will listen on the IP address assigned to this interface. Click **NEXT**.

#. On the **Volume Parameters** tab, specify the hostname or IP address of the NFS share as well as the export name. Click **NEXT**.

#. On the **DNS Configuration** tab, specify the external DNS name for this gateway, e.g, ``backupgateway.example.com``. Make sure that each node running the gateway service has a port open for outgoing Internet connections and incoming connections from your Acronis backup software. Backup agents will use this address and port to upload the backed-up data.

   .. important:: 

      #. Configure your DNS server according to the example suggested in the management panel.
      #. Each time you changes nodes in the Acronis Backup Gateway cluster, adjust the DNS settings accordingly.

#. Click **NEXT**.

#. Depending on the Acronis product you use, specify the following on the **Registration** tab:

   - In **Account Server Name**, specify the address of the Acronis Backup Cloud management portal (e.g., https://cloud.acronis.com/) or the hostname/IP address and port of the Acronis Backup Advanced management server (e.g., http://192.168.1.2:9877).

   - In **Acronis Account**, specify the credentials of the Acronis Backup Cloud or Acronis Backup Advanced administrator account.

#. Click **DONE**.
