SmbMountOptions - Amazon DataSync
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.


Specifies the version of the Server Message Block (SMB) protocol that Amazon DataSync uses to access an SMB file server.



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 a protocol version that they mutually support. (DataSync supports SMB versions 2.1.0 and later.)

    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 2.1.0.

Type: String

Valid Values: AUTOMATIC | SMB2 | SMB3

Required: No
