Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

AWS DataSync is a managed data transfer service that makes it simpler for you to automate moving data between on-premises storage and Amazon Simple Storage Service (Amazon S3) or Amazon Elastic File System (Amazon EFS).

This API interface reference for AWS DataSync contains documentation for a programming interface that you can use to manage AWS DataSync.

Sending a Request Using DataSync

var datasync = new AWS.DataSync();
datasync.cancelTaskExecution(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the DataSync object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var datasync = new AWS.DataSync({apiVersion: '2018-11-09'});

You can also set the API version globally in AWS.config.apiVersions using the datasync service identifier:

AWS.config.apiVersions = {
  datasync: '2018-11-09',
  // other service API versions
};

var datasync = new AWS.DataSync();

Constructor Details

new AWS.DataSync(options = {}) ⇒ Object

Constructs a service object. This object has one method for each API operation.

Examples:

Constructing a DataSync object

var datasync = new AWS.DataSync({apiVersion: '2018-11-09'});

Options Hash (options):

  • params (map)

    An optional map of parameters to bind to every request sent by this service object. For more information on bound parameters, see "Working with Services" in the Getting Started Guide.

  • endpoint (String)

    The endpoint URI to send requests to. The default endpoint is built from the configured region. The endpoint should be a string like 'https://{service}.{region}.amazonaws.com'.

  • sslEnabled (Boolean)

    whether to enable SSL for requests.

  • paramValidation (Boolean|map)

    whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:

    • min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
    • max [Boolean] — Validates that a value meets the max constraint.
    • pattern [Boolean] — Validates that a string value matches a regular expression.
    • enum [Boolean] — Validates that a string value matches one of the allowable enum values.
  • computeChecksums (Boolean)

    whether to compute checksums for payload bodies when the service accepts it (currently supported in S3 only)

  • convertResponseTypes (Boolean)

    whether types are converted when parsing response data. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads. Defaults to true.

Method Details

cancelTaskExecution(params = {}, callback) ⇒ AWS.Request

Cancels execution of a task.

When you cancel a task execution, the transfer of some files are abruptly interrupted. The contents of files that are transferred to the destination might be incomplete or inconsistent with the source files. However, if you start a new task execution on the same task and you allow the task execution to complete, file content on the destination is complete and consistent. This applies to other unexpected failures that interrupt a task execution. In all of these cases, AWS DataSync successfully complete the transfer when you start the next task execution.

Service Reference:

Examples:

Calling the cancelTaskExecution operation

var params = {
  TaskExecutionArn: 'STRING_VALUE' /* required */
};
datasync.cancelTaskExecution(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • TaskExecutionArn — (String)

      The Amazon Resource Name (ARN) of the task execution to cancel.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

createAgent(params = {}, callback) ⇒ AWS.Request

Activates an AWS DataSync agent that you have deployed on your host. The activation process associates your agent with your account. In the activation process, you specify information such as the AWS Region that you want to activate the agent in. You activate the agent in the AWS Region where your target locations (in Amazon S3 or Amazon EFS) reside. Your tasks are created in this AWS Region.

You can use an agent for more than one location. If a task uses multiple agents, all of them need to have status AVAILABLE for the task to run. If you use multiple agents for a source location, the status of all the agents must be AVAILABLE for the task to run. For more information, see Activating a Sync Agent in the AWS DataSync User Guide.

Agents are automatically updated by AWS on a regular basis, using a mechanism that ensures minimal interruption to your tasks.

Service Reference:

Examples:

Calling the createAgent operation

var params = {
  ActivationKey: 'STRING_VALUE', /* required */
  AgentName: 'STRING_VALUE',
  Tags: [
    {
      Key: 'STRING_VALUE',
      Value: 'STRING_VALUE'
    },
    /* more items */
  ]
};
datasync.createAgent(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • ActivationKey — (String)

      Your agent activation key. You can get the activation key either by sending an HTTP GET request with redirects that enable you to get the agent IP address (port 80). Alternatively, you can get it from the AWS DataSync console.

      The redirect URL returned in the response provides you the activation key for your agent in the query string parameter activationKey. It might also include other activation-related parameters; however, these are merely defaults. The arguments you pass to this API call determine the actual configuration of your agent. For more information, see Activating a Sync Agent in the AWS DataSync User Guide.

});

Parameters:

  • params (Object) (defaults to: {})
    • Subdirectory — (String)

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

      To see all the paths exported by your NFS server. run "showmount -e nfs-server-name" from an NFS client that has access to your server. You can specify any directory that appears in the results, and any subdirectory of that directory. Ensure that the NFS export is accessible without Kerberos authentication.

      To transfer all the data in the folder you specified, DataSync needs to have permissions to read all the data. To ensure this, either configure the NFS export with no_root_squash, or ensure that the permissions for all of the files that you want sync allow read access for all users. Doing either enables the agent to read the files. For the agent to access directories, you must additionally enable all execute access. For information about NFS export configuration, see 18.7. The /etc/exports Configuration File in the Centos documentation.

    • ServerHostname — (String)

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

      Note: This name must either be DNS-compliant or must be an IP version 4 (IPv4) address.
    • OnPremConfig — (map)

      Contains a list of Amazon Resource Names (ARNs) of agents that are used to connect to an NFS server.

      • AgentArnsrequired — (Array<String>)

        ARNs)of the agents to use for an NFS location.

    • Tags — (Array<map>)

      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.

      • Key — (String)

        The key for an AWS resource tag.

      • Value — (String)

        The value for an AWS resource tag.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

Returns:

  • (AWS.Request)

    a handle to the operation request for subsequent event callback registration.

createLocationS3(params = {}, callback) ⇒ AWS.Request

Creates an endpoint for an Amazon S3 bucket.

For AWS DataSync to access a destination S3 bucket, it needs an AWS Identity and Access Management (IAM) role that has the required permissions. You can set up the required permissions by creating an IAM policy that grants the required permissions and attaching the policy to the role. An example of such a policy is shown in the examples section. For more information, see Configuring Amazon S3 Location Settings in the AWS DataSync User Guide.

Service Reference:

Examples:

Calling the createLocationS3 operation

var params = {
  S3BucketArn: 'STRING_VALUE', /* required */

createTask(params = {}, callback) ⇒ AWS.Request

Creates a task. A task is a set of two locations (source and destination) and a set of default OverrideOptions that you use to control the behavior of a task. If you don't specify default values for Options when you create a task, AWS DataSync populates them with safe service defaults.

When you initially create a task, it enters the INITIALIZING status and then the CREATING status. In CREATING status, AWS DataSync attempts to mount the source Network File System (NFS) location. The task transitions to the AVAILABLE status without waiting for the destination location to mount. Instead, AWS DataSync mounts a destination before every task execution and then unmounts it after every task execution.

If an agent that is associated with a source (NFS) location goes offline, the task transitions to the UNAVAILABLE status. If the status of the task remains in the CREATING status for more than a few minutes, it means that your agent might be having trouble mounting the source NFS file system. Check the task's ErrorCode and ErrorDetail. Mount issues are often caused by either a misconfigured firewall or a mistyped NFS server host name.

Service Reference:

Examples:

Calling the createTask operation

var params = {
  DestinationLocationArn: 'STRING_VALUE', /* required */
  SourceLocationArn: 'STRING_VALUE', /* required */

    VerifyMode: POINT_IN_TIME_CONSISTENT | NONE
  },
  Tags: [
    {
      Key: 'STRING_VALUE',
      Value: 'STRING_VALUE'
    },
    /* more items */
  ]
};
datasync.createTask(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • SourceLocationArn — (String)

      The Amazon Resource Name (ARN) of the source location for the task.

    • DestinationLocationArn — (String)

      The Amazon Resource Name (ARN) of an AWS storage resource's location.

    • CloudWatchLogGroupArn — (String)

      The Amazon Resource Name (ARN) of the Amazon CloudWatch log group that is used to monitor and log events in the task. For more information on these groups, see Working with Log Groups and Log Streams in the Amazon CloudWatch User Guide.

      For more information about how to useCloudWatchLogs with DataSync, see Monitoring Your Task.

    • Name — (String)

      The name of a task. This value is a text reference that is used to identify the task in the console.

    • Options — (map)

      The set of configuration options that control the behavior of a single execution of the task that occurs when you call StartTaskExecution. You can configure these options to preserve metadata such as user ID (UID) and group ID (GID), file permissions, data integrity verification, and so on.

      For each individual task execution, you can override these options by specifying the OverrideOptions before starting a the task execution. For more information, see the operation.

      • VerifyMode — (String)

        A value that determines whether a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred.

        Default value: POINT_IN_TIME_CONSISTENT.

        POINT_IN_TIME_CONSISTENT: Perform verification (recommended).

        NONE: Skip verification.

        Possible values include:
        • "POINT_IN_TIME_CONSISTENT"
        • "NONE"
      • Atime — (String)

        A file metadata value that shows the last time a file was accessed (that is, when the file was read or written to). If you set Atime to BEST_EFFORT, DataSync attempts to preserve the original Atime attribute on all source files (that is, the version before the PREPARING phase). However, Atime's behavior is not fully standard across platforms, so AWS DataSync can only do this on a best-effort basis.

        Default value: BEST_EFFORT.

Returns detailed metadata about a task that is being executed.

Service Reference:

Examples:

Calling the describeTaskExecution operation

var params = {
  TaskExecutionArn: 'STRING_VALUE' /* required */
};
datasync.describeTaskExecution(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • TaskExecutionArn — (String)

      The Amazon Resource Name (ARN) of the task that is being executed.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response)

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error)

      the error object returned from the request. Set to null if the request is successful.

    • data (Object)

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • TaskExecutionArn — (String)

        The Amazon Resource Name (ARN) of the task execution that was described. TaskExecutionArn is hierarchical and includes TaskArn for the task that was executed.

        For example, a TaskExecution value with the ARN arn:aws:sync:us-east-1:209870788375:task/task-0208075f79cedf4a2/execution/exec-08ef1e88ec491019b executed the task with the ARN arn:aws:sync:us-east-1:209870788375:task/task-0208075f79cedf4a2.

        • "SUCCESS"
        • "ERROR"
      • Options — (map)

        Represents the options that are available to control the behavior of a StartTaskExecution operation. Behavior includes preserving metadata such as user ID (UID), group ID (GID), and file permissions, and also overwriting files in the destination, data integrity verification, and so on.

        A task has a set of default options associated with it. If you don't specify an option in StartTaskExecution, the default value is used. You can override the defaults options on each task execution by specifying an overriding Options value to StartTaskExecution.

        • VerifyMode — (String)

          A value that determines whether AWS DataSync should preserve the metadata of block and character devices in the source file system, and recreate the files with that device name and metadata on the destination.

          Note: AWS DataSync can't sync the actual contents of such devices, because they are nonterminal and don't return an end-of-file (EOF) marker.

          Default value: NONE.

          NONE: Ignore special devices (recommended).

          PRESERVE: Preserve character and block device metadata. This option isn't currently supported for Amazon EFS.

        The time that the task execution was started.

      • EstimatedFilesToTransfer — (Integer)

        The expected number of files that is to be transferred over the network. This value is calculated during the PREPARING phase, before the TRANSFERRING phase. This value is the expected number of files to be transferred. It's calculated based on comparing the content of the source and destination locations and finding the delta that needs to be transferred.

      • EstimatedBytesToTransfer — (Integer)

        The estimated physical number of bytes that is to be transferred over the network.

      • FilesTransferred — (Integer)

        The actual number of files that was transferred over the network. This value is calculated and updated on an ongoing basis during the TRANSFERRING phase. It's updated periodically when each file is read from the source and sent over the network.

        If failures occur during a transfer, this value can be less than EstimatedFilesToTransfer. This value can also be greater than EstimatedFilesTransferred in some cases.

        A value that determines whether a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred.

        Default value: POINT_IN_TIME_CONSISTENT.

        POINT_IN_TIME_CONSISTENT: Perform verification (recommended).

        NONE: Skip verification.

        • "NONE"
      • Atime — (String)

        A file metadata value that shows the last time a file was accessed (that is, when the file was read or written to). If you set Atime to BEST_EFFORT, DataSync attempts to preserve the original Atime attribute on all source files (that is, the version before the PREPARING phase). However, Atime's behavior is not fully standard across platforms, so AWS DataSync can only do this on a best-effort basis.

        Default value: BEST_EFFORT.

        BEST_EFFORT: Attempt to preserve the per-file Atime value (recommended).

        NONE: Ignore Atime.

        Note: If Atime is set to BEST_EFFORT, Mtime must be set to PRESERVE. If Atime is set to NONE, Mtime must also be NONE.
        Possible values include:
        • "NONE"
        • "BEST_EFFORT"
      • Mtime — (String)

        Default value: PRESERVE.

        PRESERVE: Preserve original Mtime (recommended)

        NONE: Ignore Mtime.

        Note: If Mtime is set to PRESERVE, Atime must be set to BEST_EFFORT. If Mtime is set to NONE, Atime must also be set to NONE.
        Possible values include:
        • "NONE"
        • "PRESERVE"
      • Uid — (String)

        Possible values include:
        • "PRESERVE"
        • "REMOVE"
      • PreserveDevices — (String)

        A value that determines whether AWS DataSync should preserve the metadata of block and character devices in the source file system, and recreate the files with that device name and metadata on the destination.

        Note: AWS DataSync can't sync the actual contents of such devices, because they are nonterminal and don't return an end-of-file (EOF) marker.

        Default value: NONE.

        NONE: Ignore special devices (recommended).

        PRESERVE: Preserve character and block device metadata. This option isn't currently supported for Amazon EFS.
