Answer: Implement a backup strategy with AWS Backup, enabling cross-Region backups for EC2 instances.
The most cost-effective solution for backing up EC2 instances to a second Region while centrally managing them is to use AWS Backup with cross-Region backup enabled. This approach leverages AWS Backup's built-in functionality to automate and manage backups efficiently, reducing operational overhead and costs compared to other methods such as maintaining a parallel set of EC2 instances or using data replication tools.
