Amazon DynamoDB now helps you meet regulatory compliance and business continuity requirements through enhanced backup features, including copying on-demand backups cross-account and cross-Region, cost allocation tagging for backups, and transitioning backups to cold storage. In addition, backups managed through AWS Backup are now stored in the AWS Backup vault, which allows you to encrypt and secure your backups by using AWS Key Management Service (KMS) key that is independent from your DynamoDB table encryption key.
