title: Understanding AWS RDS Point in time recovery with automated backups
body: <p>I'm trying to understand the process of AWS RDS point in time recovery. When I create a new DB Instance and enable automated backups for that instance, I get the ability to restore to LatestRestorableTime which is approximately 5 minutes behind the current time. </p>
  
  <p>So I can always restore to a new DB instance from the actual base instance while probably loosing the data that may have been inserted or updated in last 5 minutes.</p>
  
  <p>So how does AWS achieves this? Is it like AWS keeps the log of all changes from the last automated backup snapshot and applies those logs to the last automated snapshot.</p>
