Amazon Data Lifecycle Manager default policies now supports AWS Organizations

Customers can now create and manage default policies across their entire organization or organizational unit (OU) with AWS CloudFormation StackSets. Default policies work in conjunction with customers’ existing backup mechanisms to only create EBS-backed AMIs and EBS Snapshots of instances and volumes without recent backups. This helps administrators ensure that all member accounts have comprehensive backup protection without creating duplicate backups or increasing management overhead and cost.
