<pre>
A task will be [scheduled][google.cloud.tasks.v2beta3.Task.schedule_time]
for retry between
[min_backoff][google.cloud.tasks.v2beta3.RetryConfig.min_backoff] and
[max_backoff][google.cloud.tasks.v2beta3.RetryConfig.max_backoff] duration
after it fails, if the queue's
[RetryConfig][google.cloud.tasks.v2beta3.RetryConfig] specifies that the
task should be retried.

If unspecified when the queue is created, Cloud Tasks will pick the
default.


`min_backoff` will be truncated to the nearest second.

This field has the same meaning as
[min_backoff_seconds in
queue.yaml/xml](https://cloud.google.com/appengine/docs/standard/python/config/queueref#retry_parameters).
