Which solution will meet these requirements with the LEAST operational overhead?
Use AWS Backup to copy EC2 backups and RDS backups to the separate Region.
Use Amazon Data Lifecycle Manager (Amazon DLM) to copy EC2 backups and RDS backups to the separate Region.
Create Amazon Machine Images (AMIs) of the EC2 instances. Copy the AMIs to the separate Region. Create a read replica for the RDS DB instance in the separate Region.
Create Amazon Elastic Block Store (Amazon EBS) snapshots. Copy the EBS snapshots to the separate Region. Create RDS snapshots. Export the RDS snapshots to Amazon S3. Configure S3 Cross-Region Replication (CRR) to the separate Region.
Explanations:
AWS Backup simplifies and automates backup processes across AWS services, allowing for easy configuration to copy backups to a separate Region with minimal operational overhead.
Amazon Data Lifecycle Manager (DLM) is primarily for automating EBS snapshot management, but it does not provide a direct solution for cross-Region backups for both EC2 and RDS.
While creating AMIs and RDS read replicas can back up data, it involves more manual steps and operational overhead compared to using AWS Backup.
This solution involves multiple manual steps, including managing EBS snapshots and RDS snapshots, and setting up S3 CRR, resulting in higher operational overhea
I categorize that the answer is:
Use AWS Backup to copy EC2 backups and RDS backups to the separate Region.
