This tier is intended for data that will remain in the cool tier for at least 30 days. Example usage scenarios for the cool access tier include:
                                                                                            Short-term backup and disaster recovery

                                                                                            Cool - Optimized for storing data that is infrequently accessed and stored for at least 30 days.
