# UpdateTaskExecution
<a name="API_UpdateTaskExecution"></a>

Updates the configuration of a running AWS DataSync task execution.

## Request Parameters
<a name="API_UpdateTaskExecution_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [Options](#API_UpdateTaskExecution_RequestSyntax) **   <a name="DataSync-UpdateTaskExecution-request-Options"></a>
Indicates how your transfer task is configured. These options include how DataSync handles files, objects, and their associated metadata during your transfer. You also can specify how to verify data integrity, set bandwidth limits for your task, among other options.  
Each option has a default value. Unless you need to, you don't have to configure any option before calling [StartTaskExecution](https://docs.aws.amazon.com/datasync/latest/userguide/API_StartTaskExecution.html).  
You also can override your task options for each task execution. For example, you might want to adjust the `LogLevel` for an individual execution.
