DB Instance Backups
For all backup types, Amazon RDS creates a storage volume snapshot of your DB instance, backing up the entire DB instance and not just individual databases.
Amazon RDS creates automated backups of your DB instance during the backup window of your DB instance. Amazon RDS saves the automated backups of your DB instance according to the backup retention period of your database. For more information, see Working With Backups.
You can also backup your DB instance manually, by manually creating a DB snaphot. A DB snapshot is a user-initiated storage volume snapshot of your DB instance, backing up the entire DB instance and not just individual databases. DB snapshots enable you to back up your DB instance in a known state as frequently as you wish, and then restore to that specific state at any time. DB snapshots are kept until you explicitly delete them. For more information on working with DB snapshots, see Creating a DB Snapshot and Restoring From a DB Snapshot.
In addition to daily automated backups, Amazon RDS also archives database change logs. This enables you to recover your database to any point in time during the backup retention period, up to the last five minutes of database usage. For more information on working with point-in-time recovery, see Restoring a DB Instance to a Specified Time.
