Question #974
A company uses an on-premises tape backup system and wants to integrate it with AWS Cloud to archive old backups without replacing their existing infrastructure. Which AWS service should the company use to achieve this?
Amazon Elastic File System (Amazon EFS)
Amazon Elastic Block Store (Amazon EBS)
Amazon S3
AWS Storage Gateway
Explanation
The correct answer is D. AWS Storage Gateway. Here's why:
- AWS Storage Gateway (Tape Gateway): Designed specifically to integrate on-premises backup systems with AWS. It emulates a virtual tape library (VTL), allowing existing tape-based backup software to write backups to virtual tapes stored in Amazon S3 or Glacier. This meets the requirement of retaining existing infrastructure while archiving backups in the cloud.
- Why other options are incorrect:
- A. Amazon EFS: A cloud-only file storage service for EC2 instances, not compatible with on-premises tape systems.
- B. Amazon EBS: Block storage for EC2 instances, not designed for hybrid tape backup integration.
- C. Amazon S3: While S3 is used for storage, it lacks native integration with tape systems. Storage Gateway acts as the intermediary.
Key Points:
- Use Storage Gateway's Tape Gateway for hybrid tape-to-cloud workflows.
- Virtual tapes are stored in S3/Glacier, enabling cost-effective long-term archiving.
- No changes to existing backup processes are required.
Answer
The correct answer is: D
