Question

A CloudOps engineer manages a fleet of EC2 instances backing a transaction-processing application. The business requires that no more than 1 hour of data can be lost in the event of a volume failure, and backups must be automated and retained for 30 days with the least operational overhead. The team currently uses AWS Backup with EBS snapshots. What configuration best meets the recovery point objective (RPO)?

Accepted Answer

Create an AWS Backup plan with a backup rule that runs on an hourly schedule and a 30-day retention period, assigned to the volumes via resource tags.

Answer

Create an AWS Backup plan with a daily backup rule and enable continuous backups with point-in-time recovery for the EBS volumes.

Answer

Write a Lambda function triggered every hour by EventBridge to call CreateSnapshot on each volume and a second function to delete snapshots older than 30 days.

Answer

Create an AWS Backup plan with a daily backup rule and copy each recovery point to a second Region every hour to reduce the RPO to 1 hour.
