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 in 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?

A
Amazon FSx for Windows File Server with a Multi-AZ deployment
B
Amazon FSx for NetApp ONTAP with a Multi-AZ deployment
C
Amazon Elastic File System (Amazon EFS) with the Standard storage class
D
Amazon FSx for OpenZFS

Explanation
Correct Answer: B - Amazon FSx for NetApp ONTAP with a Multi-AZ deployment
Here's why this is the correct solution:
Key Requirements Analysis:
- Containerized application using Amazon ECS - All options support this
- Shared file system access - All options provide shared file systems
- Highly durable - All AWS file services are highly durable
- Recover data to another AWS Region with RPO of 8 hours - This is the critical requirement
- Mount target in each Availability Zone within a Region - All options can provide this
- Use AWS Backup to manage replication to another Region - This is the key differentiator
Why Amazon FSx for NetApp ONTAP is correct:
-
AWS Backup Integration: Amazon FSx for NetApp ONTAP fully integrates with AWS Backup for cross-region backup and restore operations. AWS Backup can manage the replication to another region.
-
Multi-AZ Deployment: FSx for ONTAP supports Multi-AZ deployments which provide high availability within a region and mount targets in each Availability Zone.
-
Cross-Region Recovery: AWS Backup can create backup copies in another region, meeting the RPO of 8 hours requirement.
-
RPO Compliance: With AWS Backup, you can schedule backups to meet specific RPO requirements, including 8-hour intervals.
Why other options are incorrect:
A. Amazon FSx for Windows File Server with a Multi-AZ deployment:
- While it supports Multi-AZ, AWS Backup for FSx for Windows File Server does not support cross-region backup/restore natively. Cross-region replication would require other mechanisms.
C. Amazon Elastic File System (Amazon EFS) with the Standard storage class:
- EFS does support cross-region replication, but it uses EFS replication (not AWS Backup). The requirement specifically states to use AWS Backup to manage the replication.
- EFS replication is a separate feature from AWS Backup.
D. Amazon FSx for OpenZFS:
- AWS Backup for FSx for OpenZFS does not support cross-region backup/restore. It only supports backups within the same region.
Additional Considerations:
- RPO of 8 hours: AWS Backup allows you to configure backup schedules to meet specific RPO requirements. You can set backup frequency to meet the 8-hour target.
- Mount targets in each AZ: FSx for ONTAP Multi-AZ deployment automatically creates mount points in each Availability Zone.
- Container integration: FSx for ONTAP supports NFS protocol which works well with containerized applications on ECS.
This solution provides the required durability, cross-region recovery capability using AWS Backup, and meets all the specified requirements.
