What should a solutions architect recommend?
Set up AWS Storage Gateway to connect with the backup applications using the NFS interface.
Set up an Amazon EFS file system that connects with the backup applications using the NFS interface.
Set up an Amazon EFS file system that connects with the backup applications using the iSCSI interface.
Set up AWS Storage Gateway to connect with the backup applications using the iSCSI-virtual tape library (VTL) interface.
Explanations:
AWS Storage Gateway can connect using NFS, but it is not ideal for preserving investments in physical backup tape workflows, as NFS is not a tape-replacement solution.
Amazon EFS does not support backup tape workflows and is more suited for file-based workloads, not for integrating with traditional backup applications.
Amazon EFS does not support iSCSI and is not designed for backup applications that require tape-based or block-level storage integration.
AWS Storage Gateway with the iSCSI-VTL interface is designed to integrate with backup applications that rely on physical tape workflows, preserving existing investments while transitioning to the cloud.
