A company is using a tape backup solution to store its key application data offsite.The daily data volume is around 50 TB.The company needs to retain the backups for 7 years for regulatory purposes.The backups are rarely accessed, and a week’s notice is typically given if a backup needs to be restored.The company is now considering a cloud-based option to reduce the storage costs and operational burden of managing tapes.The company also wants to make sure that the transition from tape backups to the cloud minimizes disruptions.

Which storage solution is MOST cost-effective?

Use Amazon Storage Gateway to back up to Amazon Glacier Deep Archive.

Use AWS Snowball Edge to directly integrate the backups with Amazon S3 Glacier.

Copy the backup data to Amazon S3 and create a lifecycle policy to move the data to Amazon S3 Glacier.

Use Amazon Storage Gateway to back up to Amazon S3 and create a lifecycle policy to move the backup to Amazon S3 Glacier.

Explanations:

Amazon Storage Gateway allows seamless integration with on-premises backup solutions, and Amazon Glacier Deep Archive is the most cost-effective solution for long-term storage.

AWS Snowball Edge is typically used for large-scale data migration to the cloud, not for ongoing, incremental backup. It is not optimized for regular backup and retrieval tasks.

Storing backups first in Amazon S3 adds unnecessary costs, as data can go directly to Glacier Deep Archive through Storage Gateway, saving on storage and lifecycle costs.

Using Amazon S3 with lifecycle policies adds additional costs for storage in S3 before moving to Glacier. Direct backup to Glacier Deep Archive is more cost-efficient.
