Which of the following is the most cost-effective option to implement this solution?

An organization is currently using a tape backup solution to store its application data on-premises. They plan to use a cloud storage service to preserve the backup data for up to 10 years that may be accessed about once or twice a year.

Which of the following is the most cost-effective option to implement this solution?
A . Order an AWS Snowball Edge appliance to import the backup directly to Amazon S3 Glacier.
B . Use AWS Storage Gateway to backup the data directly to Amazon S3 Glacier.
C . Use Amazon S3 to store the backup data and add a lifecycle rule to transition the current version to Amazon S3 Glacier.
D . Use AWS Storage Gateway to backup the data directly to Amazon S3 Glacier Deep Archive.

Answer: D

Explanation:

Tape Gateway enables you to replace using physical tapes on-premises with virtual tapes in AWS without changing existing backup workflows. Tape Gateway supports all leading backup applications and caches virtual tapes on-premises for low-latency data access. Tape Gateway encrypts data between the gateway and AWS for secure data transfer and compresses data and transitions virtual tapes between Amazon S3 and Amazon S3 Glacier, or Amazon S3 Glacier Deep Archive, to minimize storage costs.

The scenario requires you to backup your application data to a cloud storage service for long-term retention of data that will be retained for 10 years. Since it uses a tape backup solution, an option that uses AWS Storage Gateway must be the possible answer. Tape Gateway can move your virtual tapes archived in Amazon S3 Glacier or Amazon S3 Glacier Deep Archive storage class, enabling you to further reduce the monthly cost to store long-term data in the cloud by up to 75%.

Hence, the correct answer is: Use AWS Storage Gateway to backup the data directly to Amazon S3 Glacier Deep Archive.

The option that says: Use AWS Storage Gateway to backup the data directly to Amazon S3 Glacier is incorrect. Although this is a valid solution, moving to S3 Glacier is more expensive than directly backing it up to Glacier Deep Archive.

The option that says: Order an AWS Snowball Edge appliance to import the backup directly to Amazon S3 Glacier is incorrect because Snowball Edge can’t directly integrate backups to S3 Glacier. Moreover, you have to use the Amazon S3 Glacier Deep Archive storage class as it is more cost-effective than the regular Glacier class.

The option that says: Use Amazon S3 to store the backup data and add a lifecycle rule to transition the current version to Amazon S3 Glacier is incorrect. Although this is a possible solution, it is difficult to directly integrate a tape backup solution to S3 without using Storage Gateway. References:
