Which AWS service should the company use to meet this requirement?
Amazon Elastic Block Store (Amazon EBS)
Amazon S3
Amazon Elastic File System (Amazon EFS)
AWS Storage Gateway
Explanations:
Amazon Elastic Block Store (Amazon EBS) is primarily used for block storage attached to EC2 instances, not for extending physical tape library storage or for backup storage needs.
Amazon S3 is an object storage service suitable for general storage, archiving, and backup but does not integrate specifically with physical tape libraries.
Amazon Elastic File System (Amazon EFS) is used for scalable, managed file storage for Linux-based workloads and is not intended for tape library extension or data archiving.
AWS Storage Gateway, specifically the Tape Gateway option, is designed to extend physical tape libraries to the cloud, enabling seamless backups to AWS.
