What solution should be recommended for migrating tape backup processes to the cloud while maintaining iSCSI compatibility?

1. Use Amazon S3

2. Implement AWS Snowball

3. Utilize AWS Storage Gateway

4. Adopt Amazon EBS

The correct answer is: Utilize AWS Storage Gateway

Utilizing AWS Storage Gateway is the optimal solution for migrating tape backup processes to the cloud while ensuring iSCSI compatibility. AWS Storage Gateway acts as a bridge between on-premises environments and AWS cloud storage services, allowing organizations to maintain compatibility with existing iSCSI applications while benefiting from cloud storage. Storage Gateway offers a specific configuration called Tape Gateway, which emulates traditional tape libraries and allows you to back up your data to Amazon S3 in a way that resembles the behavior of physical tape. This means you can seamlessly transition your tape backups to the cloud without needing to modify your existing backup software significantly. As a result, organizations can leverage the scalability, durability, and cost-effectiveness of cloud storage while still using familiar iSCSI protocols. In contrast, other solutions do not provide the same level of direct compatibility with iSCSI applications or are not focused on tape migration. Amazon S3 is primarily for object storage and does not inherently support iSCSI without additional layers. AWS Snowball is designed for large-scale data transfer and is typically used when the data set is too large to transfer over the network but does not retain iSCSI compatibility for applications. Amazon EBS is block storage targeted at EC2 instances and is not intended for tape migration
