Request Syntax

response = client.update_location_nfs(
        'AgentArns': [
        'Version': 'AUTOMATIC'|'NFS3'|'NFS4_0'|'NFS4_1'
  • LocationArn (string) –


    Specifies the Amazon Resource Name (ARN) of the NFS transfer location that you want to update.

  • Subdirectory (string) –

    Specifies the export path in your NFS file server that you want DataSync to mount.

    This path (or a subdirectory of the path) is where DataSync transfers data to or from. For information on configuring an export for DataSync, see Accessing NFS file servers.

  • OnPremConfig (dict) –

    The DataSync agents that are connecting to a Network File System (NFS) location.

    • AgentArns (list) – [REQUIRED]

      The Amazon Resource Names (ARNs) of the agents connecting to a transfer location.

      • (string) –

  • MountOptions (dict) –

    Specifies how DataSync can access a location using the NFS protocol.

    • Version (string) –

      Specifies the NFS version that you want DataSync to use when mounting your NFS share. If the server refuses to use the version specified, the task fails.

      You can specify the following options:

      • AUTOMATIC (default): DataSync chooses NFS version 4.1.

      • NFS3: Stateless protocol version that allows for asynchronous writes on the server.

      • NFSv4_0: Stateful, firewall-friendly protocol version that supports delegations and pseudo file systems.

      • NFSv4_1: Stateful protocol version that supports sessions, directory delegations, and parallel data processing. NFS version 4.1 also includes all features available in version 4.0.


      DataSync currently only supports NFS version 3 with Amazon FSx for NetApp ONTAP locations.
