A global ecommerce company has many data centers around the world.With the growth of its stored data, the company needs to set up a solution to provide scalable storage for legacy on-premises file applications.The company must be able to take point-in-time copies of volumes by using AWS Backup and must retain low-latency access to frequently accessed data.The company also needs to have storage volumes that can be mounted as Internet Small Computer System Interface (iSCSI) devices from the company’s on-premises application servers.

Which solution will meet these requirements?

Provision an AWS Storage Gateway tape gateway. Configure the tape gateway to store data in an Amazon S3 bucket. Deploy AWS Backup to take point-in-time copies of the volumes.

Provision an Amazon FSx File Gateway and an Amazon S3 File Gateway. Deploy AWS Backup to take point-in-time copies of the data.

Provision an AWS Storage Gateway volume gateway in cache mode. Back up the on-premises Storage Gateway volumes with AWS Backup.

Provision an AWS Storage Gateway file gateway in cache mode. Deploy AWS Backup to take point-in-time copies of the volumes.

Explanations:

An AWS Storage Gateway tape gateway is designed for backup and archival purposes using virtual tapes in Amazon S3, but it does not provide low-latency access to frequently accessed data and cannot be mounted as iSCSI devices.

Amazon FSx File Gateway and S3 File Gateway are not specifically designed to meet the requirement of mounting storage volumes as iSCSI devices. Additionally, point-in-time backups with AWS Backup are not applicable in this context since these gateways do not provide iSCSI block storage.

Provisioning an AWS Storage Gateway volume gateway in cache mode allows for low-latency access to frequently accessed data while maintaining a copy of the data in AWS. It also supports taking point-in-time snapshots through AWS Backup and can be accessed as iSCSI devices from on-premises applications.

An AWS Storage Gateway file gateway in cache mode is designed for file storage and does not support iSCSI mounting. While it allows for caching of frequently accessed files, it does not fulfill the requirement for block storage access via iSCSI.

    I sort that the answer is:
    Provision an AWS Storage Gateway volume gateway in cache mode. Back up the on-premises Storage Gateway volumes with AWS Backup.
