--subdirectory (string)

The subdirectory in the SMB file system that is used to read data from the SMB source location or write data to the SMB destination. The SMB path should be a path that’s exported by the SMB server, or a subdirectory of that path. The path should be such that it can be mounted by other SMB clients in your network.


Subdirectory must be specified with forward slashes. For example /path/to/folder .

To transfer all the data in the folder you specified, DataSync needs to have permissions to mount the SMB share, as well as to access all the data in that share. To ensure this, either ensure that the user/password specified belongs to the user who can mount the share, and who has the appropriate permissions for all of the files and directories that you want DataSync to access, or use credentials of a member of the Backup Operators group to mount the share. Doing either enables the agent to access the data. For the agent to access directories, you must additionally enable all execute access.

--server-hostname (string)

The name of the SMB server. This value is the IP address or Domain Name Service (DNS) name of the SMB server. An agent that is installed on-premises uses this hostname to mount the SMB server in a network.


This name must either be DNS-compliant or must be an IP version 4 (IPv4) address.

--user (string)

The user who can mount the share, has the permissions to access files and folders in the SMB share.

--domain (string)

The name of the Windows domain that the SMB server belongs to.

--password (string)

The password of the user who can mount the share, has the permissions to access files and folders in the SMB share.

--agent-arns (list)

The Amazon Resource Names (ARNs) of agents to use for a Simple Message Block (SMB) location.



"string" "string" ...

--mount-options (structure)

The mount options used by DataSync to access the SMB server.

Version -> (string)

The specific SMB version that you want DataSync to use to mount your SMB share. If you don’t specify a version, DataSync defaults to AUTOMATIC . That is, DataSync automatically selects a version based on negotiation with the SMB server.

Shorthand Syntax:


JSON Syntax:

  "Version": "AUTOMATIC"|"SMB2"|"SMB3"

--tags (list)

The key-value pair that represents the tag that you want to add to the location. The value can be an empty string. We recommend using tags to name your resources.


Represents a single entry in a list of AWS resource tags. TagListEntry returns an array that contains a list of tasks when the ListTagsForResource operation is called.

Key -> (string)

The key for an AWS resource tag.

Value -> (string)

The value for an AWS resource tag.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

    "Key": "string",
    "Value": "string"

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


LocationArn -> (string)

The Amazon Resource Name (ARN) of the source SMB file system location that is created.
