A global media company is migrating its entire on-premises data center to AWS. They have several petabytes of archival data stored on tape libraries and Network Attached Storage (NAS) devices that rarely need to be accessed but must be retained for compliance reasons for 10 years. The company wants to move this data to the most cost-effective and durable storage solution on AWS while ensuring it can be retrieved if necessary. Which AWS service and configuration should a Solutions Architect recommend?

Why the other options are wrong

• A. While Tape Gateway can be used for tape data, it adds a layer of complexity and management. S3 Glacier Deep Archive can directly store all archival data, including data from NAS, in a more simplified and cost-effective manner. Mixing services unnecessarily increases management overhead.
• C. EBS Snapshots are primarily for backing up EBS volumes, not for general archival of petabytes of independent tape or NAS data. While snapshots can be archived to Glacier Deep Archive, it's not the appropriate primary mechanism for migrating and storing petabytes of diverse archival data.
• D. S3 Standard-IA is more expensive than Glacier Deep Archive and is designed for data that is accessed less frequently but still requires rapid access. For rarely accessed archival data, it's not the most cost-effective.
