The company must centrally manage and audit backups for EC2 (EBS), RDS, EFS, and DynamoDB across accounts, with scheduled policies and retention rules. Which service is designed for this?
A.Cron jobs calling per-service snapshot APIs
DIY cron scripts are error-prone, unaudited, and hard to enforce consistently.
B.AWS Backup with backup plans and vaults
Correct. AWS Backup is the managed, centralized backup service.
C.Amazon S3 Glacier vaults accessed directly
Glacier is a storage tier, not a cross-service backup orchestrator.
D.AWS CloudTrail log archiving
CloudTrail records API activity; it does not back up workloads.
Why this answer
AWS Backup provides centralized, policy-driven backup across EBS, RDS, EFS, DynamoDB, and more — including cross-account and cross-Region copies, retention rules, and audit via AWS Backup Audit Manager.
