StartTaskExecution

Starts a specific invocation of a task. A TaskExecution value represents an individual run of a task. Each task can have at most one TaskExecution at a time.

TaskExecution has the following transition phases: INITIALIZING | PREPARING | TRANSFERRING | VERIFYING | SUCCESS/FAILURE.

For detailed information, see Task Execution in Components and Terminology in the AWS DataSync User Guide.

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.

Includes

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"

Type: Array of FilterRule objects

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

Required: No

OverrideOptions

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

Required: No

TaskArn

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

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}$

Required: Yes

Response Syntax

{
   "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.

TaskExecutionArn

The Amazon Resource Name (ARN) of the specific task execution that was started.

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}$
