Which AWS service provides centralized, policy-driven backup across services such as EBS, RDS, DynamoDB, and EFS?
Show answer and explanation
Answer: B
AWS Backup gives one place to define backup plans, schedules, retention, and vaults that span EBS, RDS, Aurora, DynamoDB, EFS, FSx, and more. Plans can be assigned by tag or resource ID and applied organization-wide through backup policies. It also supports cross-Region and cross-account copies into a separate vault.
Why the other options are wrong
- A. S3 versioning retains object variants inside a single bucket and does not protect databases, volumes, or file systems.
- C. Data Lifecycle Manager automates EBS snapshot and AMI lifecycles only, so it cannot cover RDS, DynamoDB, or EFS.
- D. Data Pipeline is a data movement and transformation service, not a backup manager.
