Ensure AWS RDS instances have Automatic Backup set up

Automatic Backup creates a storage volume snapshot of your DB instance, backing up the entire DB instance and not just individual databases which provide for point-in-time recovery. The automatic backup will happen during a specified backup window time and keeps the backups for a period of time defined in the retention period. It is recommended to set Automatic Backups for your critical RDS servers that will help in the data restoration process.
