Defined in:
(unknown)

Overview

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

Service Description

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 DataSync contains documentation for a programming interface that you can use to manage 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();

Method Details

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

Cancels execution of a task.

When you cancel a task execution, the transfer of some files is 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, 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 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 Amazon Web Services Region that you want to activate the agent in. You activate the agent in the Amazon Web Services Region where your target locations (in Amazon S3 or Amazon EFS) reside. Your tasks are created in this Amazon Web Services Region.

You can activate the agent in a VPC (virtual private cloud) or provide the agent access to a VPC endpoint so you can run tasks without going over the public internet.

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.

Agents are automatically updated by Amazon Web Services 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',
  SecurityGroupArns: [
    'STRING_VALUE',
    /* more items */
  ],
  SubnetArns: [
    'STRING_VALUE',
    /* more items */
  ],
  Tags: [
    {
      Key: 'STRING_VALUE', /* required */
      Value: 'STRING_VALUE'
    },
    /* more items */
  ],
  VpcEndpointId: 'STRING_VALUE'
};
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 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 an Agent in the DataSync User Guide.

    • AgentName — (String)

      The name you configured for your agent. This value is a text reference that is used to identify the agent in the console.

    • Tags — (Array<map>)

      The key-value pair that represents the tag that you want to associate with the agent. The value can be an empty string. This value helps you manage, filter, and search for your agents.

      Note: Valid characters for key and value are letters, spaces, and numbers representable in UTF-8 format, and the following special characters: + - = . _ : / @.
      • Key — required — (String)

        The key for an Amazon Web Services resource tag.

      • Value — (String)

        The value for an Amazon Web Services resource tag.

    • VpcEndpointId — (String)

      The ID of the VPC (virtual private cloud) endpoint that the agent has access to. This is the client-side VPC endpoint, also called a PrivateLink. If you don't have a PrivateLink VPC endpoint, see Creating a VPC Endpoint Service Configuration in the Amazon VPC User Guide.

      VPC endpoint ID looks like this: vpce-01234d5aff67890e1.

    • SubnetArns — (Array<String>)

      The Amazon Resource Names (ARNs) of the subnets in which DataSync will create elastic network interfaces for each data transfer task. The agent that runs a task must be private. When you start a task that is associated with an agent created in a VPC, or one that has access to an IP address in a VPC, then the task is also private. In this case, DataSync creates four network interfaces for each task in your subnet. For a data transfer to work, the agent must be able to route to all these four network interfaces.

    • SecurityGroupArns — (Array<String>)

      The ARNs of the security groups used to protect your data transfer task subnets. See SecurityGroupArns.

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:

      • AgentArn — (String)

        The Amazon Resource Name (ARN) of the agent. Use the ListAgents operation to return a list of agents for your account and Amazon Web Services Region.

Returns:

  • (AWS.Request) —

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

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

Parameters:

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

      A subdirectory in the location’s path. This subdirectory in the EFS file system is used to read data from the EFS source location or write data to the EFS destination. By default, DataSync uses the root directory.

      Note: Subdirectory must be specified with forward slashes. For example, /path/to/folder.
    • EfsFilesystemArn — (String)

      The Amazon Resource Name (ARN) for the Amazon EFS file system.

    • Ec2Config — (map)

      The subnet and security group that the Amazon EFS file system uses. The security group that you provide needs to be able to communicate with the security group on the mount target in the subnet specified.

      The exact relationship between security group M (of the mount target) and security group S (which you provide for DataSync to use at this stage) is as follows:

      • Security group M (which you associate with the mount target) must allow inbound access for the Transmission Control Protocol (TCP) on the NFS port (2049) from security group S. You can enable inbound connections either by IP address (CIDR range) or security group.

      • Security group S (provided to DataSync to access EFS) should have a rule that enables outbound connections to the NFS port on one of the file system’s mount targets. You can enable outbound connections either by IP address (CIDR range) or security group.

        For information about security groups and mount targets, see Security Groups for Amazon EC2 Instances and Mount Targets in the Amazon EFS User Guide.

      • SubnetArn — required — (String)

        The ARN of the subnet and the security group that DataSync uses to access the target EFS file system.

      • SecurityGroupArns — required — (Array<String>)

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

Defines a file system on a Network File System (NFS) server that can be read from or written to.

Service Reference:

Examples:

Calling the createLocationNfs operation

var params = {
  OnPremConfig: { /* required */
    AgentArns: [ /* required */
      'STRING_VALUE',
      /* more items */
    ]
  },
  ServerHostname: 'STRING_VALUE', /* required */
  Subdirectory: 'STRING_VALUE', /* required */
  MountOptions: {
    Version: AUTOMATIC | NFS3 | NFS4_0 | NFS4_1
  },
  Tags: [
    {
      Key: 'STRING_VALUE', /* required */
      Value: 'STRING_VALUE'
    },
    /* more items */
  ]
};
datasync.createLocationNfs(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: {}) —
    • 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 DataSync 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.

      If you are copying data to or from your Snowcone device, see NFS Server on Snowcone for more information.

      For information about NFS export configuration, see 18.7. The /etc/exports Configuration File in the Red Hat Enterprise Linux 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.

      If you are copying data to or from your Snowcone device, see NFS Server on Snowcone for more information.

      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.

      If you are copying data to or from your Snowcone device, see NFS Server on Snowcone for more information.

      • AgentArns — required — (Array<String>)

        ARNs of the agents to use for an NFS location.

    • MountOptions — (map)

      The NFS mount options that DataSync can use to mount your NFS share.

      • Version — (String)

        The specific NFS version that you want DataSync to use to mount your NFS share. If the server refuses to use the version specified, the sync will fail. If you don't specify a version, DataSync defaults to AUTOMATIC. That is, DataSync automatically selects a version based on negotiation with the NFS server.

        You can specify the following NFS versions:

        • NFSv3 - 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. Version 4.1 also includes all features available in version 4.0.

        Possible values include:
        • "AUTOMATIC"

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

Creates a task.

A task includes a source location and a destination location, and a configuration that specifies how data is transferred. A task always transfers data from the source location to the destination location. The configuration specifies options such as task scheduling, bandwidth limits, etc. A task is the complete definition of a data transfer.

When you create a task that transfers data between Amazon Web Services services in different Amazon Web Services Regions, one of the two locations that you specify must reside in the Region where DataSync is being used. The other location must be specified in a different Region.

You can transfer data between commercial Amazon Web Services Regions except for China, or between Amazon Web Services GovCloud (US) Regions.

When you use DataSync to copy files or objects between Amazon Web Services Regions, you pay for data transfer between Regions. This is billed as data transfer OUT from your source Region to your destination Region. For more information, see Data Transfer pricing.

});

Parameters:

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

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

      The Amazon Resource Name (ARN) of an Amazon Web Services 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.

    • 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 the task execution. For more information, see the StartTaskExecution 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. For more information, see Configure task settings.

        Default value: POINT_IN_TIME_CONSISTENT.

        ONLY_FILES_TRANSFERRED (recommended): Perform verification only on files that were transferred.

        POINT_IN_TIME_CONSISTENT: Scan the entire source and entire destination at the end of the transfer to verify that source and destination are fully synchronized. This option isn't supported when transferring to S3 Glacier or S3 Glacier Deep Archive storage classes.

        NONE: No additional verification is done at the end of the transfer, but all data transmissions are integrity-checked with checksum verification during the transfer.

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

        A value that determines whether files at the destination should be overwritten or preserved when copying files. If set to NEVER a destination file will not be replaced by a source file, even if the destination file differs from the source file. If you modify files in the destination and you sync the files, you can use this value to protect against overwriting those changes.

        Some storage classes have specific behaviors that can affect your S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the DataSync User Guide.

        Possible values include:
        • "ALWAYS"
        • "NEVER"
      • 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 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: OWNER_DACL.

        OWNER_DACL: For each copied object, DataSync copies the following metadata:

        • Object owner.

        • NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object.

        When choosing this option, DataSync does NOT copy the NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object.

        OWNER_DACL_SACL: For each copied object, DataSync copies the following metadata:

        • Object owner.

        • NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object.

        • NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object.

        Copying SACLs requires granting additional permissions to the Windows user that DataSync uses to access your SMB location. For information about choosing a user that ensures sufficient permissions to files, folders, and metadata, see user.

        NONE: None of the SMB security descriptor components are copied. Destination objects are owned by the user that was provided for accessing the destination location. DACLs and SACLs are set based on the destination server’s configuration.

      • 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 a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred. For more information, see Configure task settings.

          Default value: POINT_IN_TIME_CONSISTENT.

          ONLY_FILES_TRANSFERRED (recommended): Perform verification only on files that were transferred.

          POINT_IN_TIME_CONSISTENT: Scan the entire source and entire destination at the end of the transfer to verify that source and destination are fully synchronized. This option isn't supported when transferring to S3 Glacier or S3 Glacier Deep Archive storage classes.

          NONE: No additional verification is done at the end of the transfer, but all data transmissions are integrity-checked with checksum verification during the transfer.

          Possible values include:
          • "POINT_IN_TIME_CONSISTENT"

          A value that determines whether files at the destination should be overwritten or preserved when copying files. If set to NEVER a destination file will not be replaced by a source file, even if the destination file differs from the source file. If you modify files in the destination and you sync the files, you can use this value to protect against overwriting those changes.

          Some storage classes have specific behaviors that can affect your S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the DataSync User Guide.

          Possible values include:

        • 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 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)

          A value that indicates the last time that a file was modified (that is, a file was written to) before the PREPARING phase. This option is required for cases when you need to run the same task more than one time.

          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.

          A value that determines whether tasks should be queued before executing the tasks. If set to ENABLED, the tasks will be queued. The default is ENABLED.

          If you use the same agent to run multiple tasks, you can enable the tasks to run in series. For more information, see Queueing task executions.

          Possible values include:
          • "ENABLED"
          • "DISABLED"
        • LogLevel — (String)

          A value that determines the type of logs that DataSync publishes to a log stream in the Amazon CloudWatch log group that you provide. For more information about providing a log group for DataSync, see CloudWatchLogGroupArn. If set to OFF, no logs are published. BASIC publishes logs on errors for individual files transferred, and TRANSFER publishes logs for every file or object that is transferred and integrity checked.

          Possible values include:
          • "OFF"
          • "BASIC"
          • "TRANSFER"
        • TransferMode — (String)

          A value that determines whether DataSync transfers only the data and metadata that differ between the source and the destination location, or whether DataSync transfers all the content from the source, without comparing to the destination location.

          CHANGED: DataSync copies only data or metadata that is new or different content from the source location to the destination location.

          ALL: DataSync copies all source location content to the destination, without comparing to existing content on the destination.

          • "ALL"
        • SecurityDescriptorCopyFlags — (String)

          A value that determines which components of the SMB security descriptor are copied from source to destination objects.

          This value is only used for transfers between SMB and Amazon FSx for Windows File Server locations, or between two Amazon FSx for Windows File Server locations. For more information about how DataSync handles metadata, see How DataSync Handles Metadata and Special Files.

          Default value: OWNER_DACL.

          OWNER_DACL: For each copied object, DataSync copies the following metadata:

          • Object owner.

          • NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object.

          When choosing this option, DataSync does NOT copy the NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object.

          OWNER_DACL_SACL: For each copied object, DataSync copies the following metadata:

          • Object owner.

          • NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object.

          • NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object.

          Copying SACLs requires granting additional permissions to the Windows user that DataSync uses to access your SMB location. For information about choosing a user that ensures sufficient permissions to files, folders, and metadata, see user.

          NONE: None of the SMB security descriptor components are copied. Destination objects are owned by the user that was provided for accessing the destination location. DACLs and SACLs are set based on the destination server’s configuration.

      • StartTime — (Date)

        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.

          TYPE designates the type of location. Valid values: NFS | EFS | S3.

          GLOBAL_ID is the globally unique identifier of the resource that backs the location. An example for EFS is us-east-2.fs-abcd1234. An example for Amazon S3 is the bucket name, such as myBucket. An example for NFS is a valid IPv4 address or a host name compliant with Domain Name Service (DNS).

          SUBDIR is a valid file system path, delimited by forward slashes as is the *nix convention. For NFS and Amazon EFS, it's the export path to mount the location. For Amazon S3, it's the prefix path that you mount to and treat as the root of the location.

  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

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

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

    • OverrideOptions — (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 a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred. For more information, see Configure task settings.

        Default value: POINT_IN_TIME_CONSISTENT.

        ONLY_FILES_TRANSFERRED (recommended): Perform verification only on files that were transferred.

        POINT_IN_TIME_CONSISTENT: Scan the entire source and entire destination at the end of the transfer to verify that source and destination are fully synchronized. This option isn't supported when transferring to S3 Glacier or S3 Glacier Deep Archive storage classes.

        NONE: No additional verification is done at the end of the transfer, but all data transmissions are integrity-checked with checksum verification during the transfer.

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

        A value that determines whether files at the destination should be overwritten or preserved when copying files. If set to NEVER a destination file will not be replaced by a source file, even if the destination file differs from the source file. If you modify files in the destination and you sync the files, you can use this value to protect against overwriting those changes.

        Some storage classes have specific behaviors that can affect your S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the DataSync User Guide.

        Possible values include:
        • "ALWAYS"
        • "NEVER"
      • 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 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)

        A value that indicates the last time that a file was modified (that is, a file was written to) before the PREPARING phase. This option is required for cases when you need to run the same task more than one time.

        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)

        The POSIX user ID (UID) of the file's owner. This option should only be set for NFS, EFS, and S3 locations. To learn more about what metadata is copied by DataSync, see Metadata Copied by DataSync.

        Default value: INT_VALUE. This preserves the integer value of the ID.

        INT_VALUE: Preserve the integer value of UID and group ID (GID) (recommended).

        NONE: Ignore UID and GID.

        Possible values include:

        Default value: INT_VALUE. This preserves the integer value of the ID.

        INT_VALUE: Preserve the integer value of user ID (UID) and GID (recommended).

        NONE: Ignore UID and GID.

        Possible values include:
        • "NONE"
        • "INT_VALUE"
        • "NAME"
        • "BOTH"
      • PreserveDeletedFiles — (String)

        A value that specifies whether files in the destination that don't exist in the source file system should be preserved. This option can affect your storage cost. If your task deletes objects, you might incur minimum storage duration charges for certain storage classes. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the DataSync User Guide.

        Default value: PRESERVE.

        PRESERVE: Ignore such destination files (recommended).

        REMOVE: Delete destination files that aren’t present in the source.

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

        A value that determines whether DataSync should preserve the metadata of block and character devices in the source file system, and re-create the files with that device name and metadata on the destination. DataSync does not copy the contents of such devices, only the name and metadata.

        Note: 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.

        • "NONE"
        • "PRESERVE"
      • PosixPermissions — (String)

        A value that determines which users or groups can access a file for a specific purpose such as reading, writing, or execution of the file.

        Default value: PRESERVE.

        PRESERVE: Preserve POSIX-style permissions (recommended).

        NONE: Ignore permissions.

        Note: DataSync can preserve extant permissions of a source location.
        Possible values include:
        • "NONE"
        • "PRESERVE"
      • BytesPerSecond — (Integer)

        A value that limits the bandwidth used by DataSync. For example, if you want DataSync to use a maximum of 1 MB, set this value to 1048576 (=1024*1024).

      • TaskQueueing — (String)

        A value that determines whether tasks should be queued before executing the tasks. If set to ENABLED, the tasks will be queued. The default is ENABLED.

        If you use the same agent to run multiple tasks, you can enable the tasks to run in series. For more information, see Queueing task executions.

        Possible values include:
        • "ENABLED"
        • "DISABLED"
      • LogLevel — (String)

        A value that determines the type of logs that DataSync publishes to a log stream in the Amazon CloudWatch log group that you provide. For more information about providing a log group for DataSync, see CloudWatchLogGroupArn. If set to OFF, no logs are published. BASIC publishes logs on errors for individual files transferred, and TRANSFER publishes logs for every file or object that is transferred and integrity checked.

        Possible values include:
        • "OFF"
        • "BASIC"
        • "TRANSFER"
      • TransferMode — (String)

        A value that determines whether DataSync transfers only the data and metadata that differ between the source and the destination location, or whether DataSync transfers all the content from the source, without comparing to the destination location.

        CHANGED: DataSync copies only data or metadata that is new or different content from the source location to the destination location.

        ALL: DataSync copies all source location content to the destination, without comparing to existing content on the destination.

        Possible values include:
        • "CHANGED"
        • "ALL"
      • SecurityDescriptorCopyFlags — (String)

        A value that determines which components of the SMB security descriptor are copied from source to destination objects.

        This value is only used for transfers between SMB and Amazon FSx for Windows File Server locations, or between two Amazon FSx for Windows File Server locations. For more information about how DataSync handles metadata, see How DataSync Handles Metadata and Special Files.

        Default value: OWNER_DACL.

        OWNER_DACL: For each copied object, DataSync copies the following metadata:

        • Object owner.

        • NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object.

        When choosing this option, DataSync does NOT copy the NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object.

        OWNER_DACL_SACL: For each copied object, DataSync copies the following metadata:

        • Object owner.

        • NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object.

        • NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object.

        Copying SACLs requires granting additional permissions to the Windows user that DataSync uses to access your SMB location. For information about choosing a user that ensures sufficient permissions to files, folders, and metadata, see user.

        NONE: None of the SMB security descriptor components are copied. Destination objects are owned by the user that was provided for accessing the destination location. DACLs and SACLs are set based on the destination server’s configuration.

        Possible values include:
        • "NONE"
        • "OWNER_DACL"
        • "OWNER_DACL_SACL"
    • Includes — (Array<map>)

      A list of filter rules that determines which files to include when running a task. The pattern should contain a single filter string that consists of the patterns to include. The patterns are delimited by "|" (that is, a pipe), for example, "/folder1|/folder2".

Calling the updateLocationNfs operation

var params = {
  LocationArn: 'STRING_VALUE', /* required */
  MountOptions: {
    Version: AUTOMATIC | NFS3 | NFS4_0 | NFS4_1
  },
  OnPremConfig: {
    AgentArns: [ /* required */
      'STRING_VALUE',
      /* more items */
    ]
  },
  Subdirectory: 'STRING_VALUE'
};
datasync.updateLocationNfs(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: {}) —
    • LocationArn — (String)

      The Amazon Resource Name (ARN) of the NFS location to update.

    • 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 that you specified, DataSync must have permissions to read all the data. To ensure this, either configure the NFS export with no_root_squash, or ensure that the files you want DataSync to access have permissions that allow read access for all users. Doing either option enables the agent to read the files. For the agent to access directories, you must additionally enable all execute access.

      If you are copying data to or from your Snowcone device, see NFS Server on Snowcone for more information.

      For information about NFS export configuration, see 18.7. The /etc/exports Configuration File in the Red Hat Enterprise Linux documentation.

      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 a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred. For more information, see Configure task settings.

        Default value: POINT_IN_TIME_CONSISTENT.

        ONLY_FILES_TRANSFERRED (recommended): Perform verification only on files that were transferred.

        POINT_IN_TIME_CONSISTENT: Scan the entire source and entire destination at the end of the transfer to verify that source and destination are fully synchronized. This option isn't supported when transferring to S3 Glacier or S3 Glacier Deep Archive storage classes.

        NONE: No additional verification is done at the end of the transfer, but all data transmissions are integrity-checked with checksum verification during the transfer.

        • "NONE"
      • OverwriteMode — (String)

        A value that determines whether files at the destination should be overwritten or preserved when copying files. If set to NEVER a destination file will not be replaced by a source file, even if the destination file differs from the source file. If you modify files in the destination and you sync the files, you can use this value to protect against overwriting those changes.

        Some storage classes have specific behaviors that can affect your S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the DataSync User Guide.

        Possible values include:
        • "ALWAYS"
        • "NEVER"
      • 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 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)

        A value that indicates the last time that a file was modified (that is, a file was written to) before the PREPARING phase. This option is required for cases when you need to run the same task more than one time.

        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)

        Default value: INT_VALUE. This preserves the integer value of the ID.

        INT_VALUE: Preserve the integer value of UID and group ID (GID) (recommended).

        NONE: Ignore UID and GID.

        Possible values include:

        • "BOTH"
      • PreserveDeletedFiles — (String)

        A value that specifies whether files in the destination that don't exist in the source file system should be preserved. This option can affect your storage cost. If your task deletes objects, you might incur minimum storage duration charges for certain storage classes. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the DataSync User Guide.

        Default value: PRESERVE.

        PRESERVE: Ignore such destination files (recommended).

        REMOVE: Delete destination files that aren’t present in the source.

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

        A value that determines whether DataSync should preserve the metadata of block and character devices in the source file system, and re-create the files with that device name and metadata on the destination. DataSync does not copy the contents of such devices, only the name and metadata.

        Note: 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).

var params = {
  Options: { /* required */
    Atime: NONE | BEST_EFFORT,
    BytesPerSecond: 'NUMBER_VALUE',
    Gid: NONE | INT_VALUE | NAME | BOTH,
    LogLevel: OFF | BASIC | TRANSFER,
    Mtime: NONE | PRESERVE,
    OverwriteMode: ALWAYS | NEVER,
    PosixPermissions: NONE | PRESERVE,

    TransferMode: CHANGED | ALL,
    Uid: NONE | INT_VALUE | NAME | BOTH,
    VerifyMode: POINT_IN_TIME_CONSISTENT | ONLY_FILES_TRANSFERRED | NONE
  },
  TaskExecutionArn: 'STRING_VALUE' /* required */
};
datasync.updateTaskExecution(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 specific task execution that is being updated.

    • 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 a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred. For more information, see Configure task settings.

        Default value: POINT_IN_TIME_CONSISTENT.

        ONLY_FILES_TRANSFERRED (recommended): Perform verification only on files that were transferred.

        POINT_IN_TIME_CONSISTENT: Scan the entire source and entire destination at the end of the transfer to verify that source and destination are fully synchronized. This option isn't supported when transferring to S3 Glacier or S3 Glacier Deep Archive storage classes.

        NONE: No additional verification is done at the end of the transfer, but all data transmissions are integrity-checked with checksum verification during the transfer.

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

        A value that determines whether files at the destination should be overwritten or preserved when copying files. If set to NEVER a destination file will not be replaced by a source file, even if the destination file differs from the source file. If you modify files in the destination and you sync the files, you can use this value to protect against overwriting those changes.

        Some storage classes have specific behaviors that can affect your S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the DataSync User Guide.

        Possible values include:
        • "ALWAYS"
        • "NEVER"
      • 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 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)

        A value that indicates the last time that a file was modified (that is, a file was written to) before the PREPARING phase. This option is required for cases when you need to run the same task more than one time.

        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.

      • PreserveDeletedFiles — (String)

        A value that specifies whether files in the destination that don't exist in the source file system should be preserved. This option can affect your storage cost. If your task deletes objects, you might incur minimum storage duration charges for certain storage classes. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the DataSync User Guide.

        Default value: PRESERVE.

        PRESERVE: Ignore such destination files (recommended).
