In Amazon RDS, automated backups are not turned on by default

Explanation

Automated backups are turned on by default. This backs up your entire DB instance (not just individual databases on the instance) and your transaction logs. When you create your DB instance, you set a backup window that is the period of time that automatic backups occur. Typically, you want to set the window during a time when your database experiences little activity because it can cause increased latency and downtime.
