Step 4: Start a Task Execution

When a task execution starts, the task execution changes from LAUNCHING to PREPARING status within about 10 minutes. The time that the task execution takes to move through its other phases is proportional to the size of your volume. For information about task execution phases, see Task Execution.

Use the following command to start a task execution.

$ aws datasync start-task-execution --task-arn 'arn:aws:datasync:region:account-id:task/task-id'

The command returns a task execution Amazon Resource Name (ARN) similar to the one shown following.

{ "TaskExecutionArn": "arn:aws:datasync:us-east-1:209870788375:task/task-08de6e6697796f026/execution/exec-04ce9d516d69bd52f" }

You can override the task's options by specifying different options for the current execution, as shown in the example following. For a description of these options, see Options.

$ aws datasync start-task-execution [...] --override-options --VerifyMode=NONE,OverwriteMode=NEVER,PosixPermissions=NONE

When you run a task, you can optionally configure the task to include specific files, folders, and objects to transfer. For more information, see Filtering the Data Transferred by AWS DataSync.


Each agent can run a single task at a time.
