Properties

Version

By default, DataSync automatically chooses an SMB protocol version based on negotiation with your SMB file server. You also can configure DataSync to use a specific SMB version, but we recommend doing this only if DataSync has trouble negotiating with the SMB file server automatically.

These are the following options for configuring the SMB version:

  • AUTOMATIC (default): DataSync and the SMB file server negotiate the highest version of SMB that they mutually support between 2.1 and 3.1.1.

    This is the recommended option. If you instead choose a specific version that your file server doesn't support, you may get an Operation Not Supported error.

  • SMB3: Restricts the protocol negotiation to only SMB version 3.0.2.

  • SMB2: Restricts the protocol negotiation to only SMB version 2.1.

  • SMB2_0: Restricts the protocol negotiation to only SMB version 2.0.

  • SMB1: Restricts the protocol negotiation to only SMB version 1.0.

    Note

    The SMB1 option isn't available when creating an Amazon FSx for NetApp ONTAP location.

Required: No

Type: String

Allowed values: AUTOMATIC | SMB1 | SMB2_0 | SMB2 | SMB3

Update requires: No interruption
