A company has 5 PB of archived data on physical tapes. The company needs to preserve the data on the tapes for another 10 years for compliance purposes. The company wants to migrate to AWS in the next 6 months. The data center that stores the tapes has a 1 Gbps uplink internet connectivity. Which solution will meet these requirements MOST cost-effectively?

The correct option is the most cost-effective because it leverages AWS Snowball devices with Tape Gateway for offline data transfer of a large volume (5 PB) over a limited network connection (1 Gbps). Shipping Snowball devices is faster and cheaper than transferring 5 PB over a 1 Gbps link. Moving the data to S3 Glacier Deep Archive via a lifecycle policy ensures the lowest storage cost for long-term archival (10 years) while meeting compliance needs. The other options are less suitable. Using AWS DataSync with NFS storage would be too slow and expensive for 5 PB over a 1 Gbps connection. Writing directly to S3 Glacier Deep Archive from an on-premises backup application would also be bottlenecked by the network. Configuring an on-premises Tape Gateway without Snowball would still require transferring 5 PB over the slow network.
