Question
A company recently started hosting new application workloads in the AWS Cloud. The company is using Amazon EC2 instances. Amazon Elastic File System (Amazon EFS) file systems, and Amazon RDS DB instances.
To meet regulatory and business requirements, the company must make the following changes for data backups:
- Backups must be retained based on custom daily, weekly, and monthly requirements.
- Backups must be replicated to at least one other AWS Region immediately after capture.
- The backup solution must provide a single source of backup status across the AWS environment.
- The backup solution must send immediate notifications upon failure of any resource backup.
Which combination of steps will meet these requirements with the LEAST amount of operational overhead? (Choose three.)
A. Create an AWS Backup plan with a backup rule for each of the retention requirements.
B. Configure an AWS Backup plan to copy backups to another Region.
C. Create an AWS Lambda function to replicate backups to another Region and send notification if a failure occurs.
D. Add an Amazon Simple Notification Service (Amazon SNS) topic to the backup plan to send a notification for finished jobs that have any status except BACKUP_JOB_COMPLETED.
E. Create an Amazon Data Lifecycle Manager (Amazon DLM) snapshot lifecycle policy for each of the retention requirements.
F. Set up RDS snapshots on each database.
Answer
A. Create an AWS Backup plan with a backup rule for each of the retention requirements.
B. Configure an AWS Backup plan to copy backups to another Region.
D. Add an Amazon Simple Notification Service (Amazon SNS) topic to the backup plan to send a notification for finished jobs that have any status except BACKUP_JOB_COMPLETED.
Explanation
A. Create an AWS Backup plan with a backup rule for each of the retention requirements. AWS Backup allows creating backup plans with multiple backup rules to define different retention periods, such as daily, weekly, and monthly. This meets the requirement for retaining backups based on custom retention requirements.
B. Configure an AWS Backup plan to copy backups to another Region. AWS Backup supports cross-region backup replication, allowing backups to be automatically replicated to another AWS Region immediately after capture. This meets the requirement for replicating backups to at least one other AWS Region.
D. Add an Amazon Simple Notification Service (Amazon SNS) topic to the backup plan to send a notification for finished jobs that have any status except BACKUP_JOB_COMPLETED. AWS Backup integrates with Amazon SNS, allowing notifications to be sent when backup jobs fail. By configuring an SNS topic in the backup plan and setting it to send notifications for any status except BACKUP_JOB_COMPLETED, the company will receive immediate notifications upon failure of any resource backup.
This combination leverages the fully managed AWS Backup service, which provides a centralized and automated backup solution across various AWS resources, including EC2 instances, EFS file systems, and RDS databases. By using AWS Backup, the company can meet the backup requirements with minimal operational overhead, as AWS Backup handles the backup scheduling, retention, replication, and monitoring.
