# DescribeDataRepositoryTasks
<a name="API_DescribeDataRepositoryTasks"></a>

Returns the description of specific Amazon FSx for Lustre or Amazon File Cache data repository tasks, if one or more `TaskIds` values are provided in the request, or if filters are used in the request. You can use filters to narrow the response to include just tasks for specific file systems or caches, or tasks in a specific lifecycle state. Otherwise, it returns all data repository tasks owned by your AWS account in the AWS Region of the endpoint that you're calling.

When retrieving all tasks, you can paginate the response by using the optional `MaxResults` parameter to limit the number of tasks returned in a response. If more tasks remain, a `NextToken` value is returned in the response. In this case, send a later request with the `NextToken` request parameter set to the value of `NextToken` from the last response.
