Wh +When you use AWS Backup to back up an Amazon RDS DB instance, an automated snapshot might appear with an unexpected timestamp; it matches the AWS Backup snapshot creation time rather than the Amazon RDS automated backup window. If Amazon RDS does not find a recent automated backup within the past day, it consolidates the backup. Amazon RDS attaches automated backup metadata to the manual snapshot that AWS Backup created. This ensures the DB instance maintains a regular automated backup.
