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.
