AWS Config now supports AWS Backup resource types (AWS::Backup::BackupPlan, AWS::Backup::BackupSelection, AWS::Backup::BackupVault and AWS::Backup::RecoveryPoint) in all AWS Regions. AWS Config provides a detailed view of the configuration of AWS resources in your AWS account. This includes how the resources are related to one another and how they were configured. This enables you to see how the configurations and relationships have changed over time. For example, you can now use AWS Config to monitor changes to your backup plan that defines when and how you want to back up your AWS resources, monitor the resource assignment to the backup plan, track changes to the backup vault configuration or monitor changes to the recovery points for different resource types.
