Which solution will meet these requirements in the MOST operationally efficient way?
A.
Configure an AWS Lambda function to take nightly snapshots of the application's EBS volumes and to copy the snapshots to a secondary Region.
B.
Create a backup plan in AWS Backup to take nightly backups. Copy the backups to a secondary Region. Add the EC2 instances to a resource assignment as part of the backup plan.
C.
Create a backup plan in AWS Backup to take nightly backups. Copy the backups to a secondary Region. Add the EBS volumes to a resource assignment as part of the backup plan.
D.
Configure an AWS Lambda function to take nightly snapshots of the application's EBS volumes and to copy the snapshots to a secondary Availability Zone.
AWS Backup is a fully managed backup service that can create backup plans for EC2 instances, including both instance configurations and attached EBS volumes, with scheduled and cross-Region copy capabilities. By adding the EC2 instances to the resource assignment in the backup plan, AWS Backup automatically backs up all configurations and attached EBS volumes, and can copy backups to a secondary Region for disaster recovery, providing the highest operational efficiency with the least manual effort.
AWS Documentation Extract:
“AWS Backup provides fully managed backup for EC2 instances and attached EBS volumes, with scheduling, retention, and cross-Region copy built in. By adding the EC2 instance as a resource, the backup includes both configuration and attached volumes.”
(Source: AWS Backup documentation)
A, D: Custom Lambda scripts increase operational overhead and are not as integrated or robust as AWS Backup.
C: Assigning only EBS volumes does not include the EC2 instance configuration, which is needed for full recovery.
