An on-premises application writes to an SMB file share and creates a copy on a second SMB share in the same data center. The files are metadata files and image files. The company wants to store the copy on AWS and be able to access the data via SMB from either the data center or AWS in a disaster. The copy is infrequently accessed but must be available within 5 minutes. Which solution meets these requirements?

The S3 File Gateway provides an SMB file share for on-premises applications, storing data directly in Amazon S3. This meets the requirement for SMB access from the data center and AWS. S3 Standard-IA is suitable for infrequently accessed data that needs quick retrieval (within minutes), aligning with the 5-minute availability requirement. Incorrect options: AWS Outposts with EC2 and S3 storage is overly complex and expensive for this use case, and doesn't directly provide an SMB share for the on-premises application to write to S3. Amazon FSx File Gateway is designed for connecting on-premises to FSx for Windows File Server, not directly to S3, and FSx is generally more expensive than S3 for infrequently accessed data. Storing image files in S3 Glacier Deep Archive would violate the 5-minute availability requirement, as retrieval from Glacier Deep Archive can take hours.
