An ops team must centrally manage backups across EC2/EBS, RDS, DynamoDB, and EFS — with scheduled plans, retention policies, and cross-account copies for DR. Which service consolidates this?
A.AWS Backup
Correct. One service unifies backup policy and cross-account DR copies.
B.Manual snapshots via a scheduled Lambda per service
Hand-rolled snapshot jobs reinvent AWS Backup with more failure modes.
C.S3 versioning
S3 versioning covers only S3 objects, not databases or volumes.
D.CloudFormation stack sets
CloudFormation manages infrastructure, not point-in-time data backups.
Why this answer
AWS Backup provides a single backup policy engine (plans, schedules, retention, lifecycle to cold storage) across most AWS data services — plus vaults, cross-Region and cross-account copy for DR.
