Let's add one backup policy named MyBackups and attach it directly to account 123456789012. Then, we attach the AWS managed default service control policy FullAWSAccess to Root OU, so it will be inherited by all OUs and accounts in the organization. Finally, we want our workload accounts under Root/Workloads OU to be restricted to use only the allowed regions, so we attach the restrict-by-regions policy to it.
