Restoring an Amazon RDS Instance Using Snapshots

A critical part of database management is being able to recover your data after corruption or accidental deletion has occurred. In this hands-on lab, we'll use the point-in-time restore capability of RDS automated snapshots to restore a database and bring a site back up. **NOTE**: This lab may take up to 15 minutes to fully start due to the number of resources that need to be provisioned.
