DescribeTaskExecution

Returns detailed metadata about a task that is being executed.

Request Syntax

{ "TaskExecutionArn": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

TaskExecutionArn

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

Type: String

Length Constraints: Maximum length of 128.

Pattern: ^arn:(aws|aws-cn):datasync:[a-z\-0-9]*:[0-9]{12}:task/task-[0-9a-f]{17}/execution/exec-[0-9a-f]{17}$

Required: Yes

Response Syntax

{ "BytesTransferred": number, "BytesWritten": number, "EstimatedBytesToTransfer": number, "EstimatedFilesToTransfer": number, "Excludes": [ { "FilterType": "string", "Value": "string" } ], "FilesTransferred": number, "Includes": [ { "FilterType": "string", "Value": "string" } ], "Options": { "Atime": "string", "BytesPerSecond": number, "Gid": "string", "Mtime": "string", "PosixPermissions": "string", "PreserveDeletedFiles": "string", "PreserveDevices": "string", "Uid": "string", "VerifyMode": "string" }, "Result": { "ErrorCode": "string", "ErrorDetail": "string", "PrepareDuration": number, "PrepareStatus": "string", "TransferDuration": number, "TransferStatus": "string", "VerifyDuration": number, "VerifyStatus": "string" }, "StartTime": number, "Status": "string", "TaskExecutionArn": "string" }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

BytesTransferred

The physical number of bytes transferred over the network.

Type: Long

BytesWritten

The number of logical bytes written to the destination AWS storage resource.

Type: Long

EstimatedBytesToTransfer

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

Type: Long

EstimatedFilesToTransfer

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.

Type: Long

Excludes

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

Type: Array of FilterRule objects

Array Members: Minimum number of 0 items. Maximum number of 1 item.

FilesTransferred

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. This element is implementation-specific for some location types, so don't use it as an indicator for a correct file number or to monitor your task execution.

Type: Long

Includes

A list of filter rules that determines which files to include when running a task. The list 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"

Type: Array of FilterRule objects

Array Members: Minimum number of 0 items. Maximum number of 1 item.

Options

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.

Type: Options object

Result

The result of the task execution.

Type: TaskExecutionResultDetail object

StartTime

The time that the task execution was started.

Type: Timestamp

Status

The status of the task execution.

For detailed information about task execution statuses, see Understanding Task Statuses.

Type: String

Valid Values: LAUNCHING | PREPARING | TRANSFERRING | VERIFYING | SUCCESS | ERROR

TaskExecutionArn

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:datasync:us-east-1:111222333444:task/task-0208075f79cedf4a2/execution/exec-08ef1e88ec491019b executed the task with the ARN arn:aws:datasync:us-east-1:111222333444:task/task-0208075f79cedf4a2.

Type: String

Length Constraints: Maximum length of 128.

Pattern: ^arn:(aws|aws-cn):datasync:[a-z\-0-9]*:[0-9]{12}:task/task-[0-9a-f]{17}/execution/exec-[0-9a-f]{17}$

Errors

For information about the errors that are common to all actions, see Common Errors.

InternalException

This exception is thrown when an error occurs in the AWS DataSync service.

HTTP Status Code: 500

InvalidRequestException

This exception is thrown when the client submits a malformed request.

HTTP Status Code: 400
