A company is designing a containerized application that will use Amazon Elastic Container Service (Amazon ECS).The application needs to access a shared file system that is highly durable and can recover data to another AWS Region with a recovery point objective (RPO) of 8 hours.The file system needs to provide a mount target m each Availability Zone within a Region.A solutions architect wants to use AWS Backup to manage the replication to another Region.

Which solution will meet these requirements?

Amazon FSx for Windows File Server with a Multi-AZ deployment

Amazon FSx for NetApp ONTAP with a Multi-AZ deployment

Amazon Elastic File System (Amazon EFS) with the Standard storage class

Amazon FSx for OpenZFS

Explanations:

Amazon FSx for Windows File Server provides high durability and Multi-AZ deployment, but it does not natively support replication to another Region with AWS Backup. The RPO of 8 hours cannot be directly achieved using this service.

Amazon FSx for NetApp ONTAP offers Multi-AZ deployment and can support replication, but it is not integrated with AWS Backup to meet the specified RPO requirement for cross-region replication.

Amazon Elastic File System (EFS) with the Standard storage class offers durability, Multi-AZ deployment, and integration with AWS Backup to replicate data across Regions. EFS supports cross-region replication with AWS Backup, meeting the RPO requirement.

Amazon FSx for OpenZFS does not support Multi-AZ deployments in the same way as the other FSx services and does not offer cross-region replication with AWS Backup, making it unsuitable for this use case.

    I organize that the answer is:
    Amazon Elastic File System (Amazon EFS) with the Standard storage class
