title: Do I need to backup AWS EBS data?
body: <p>I am running a web-app on an AWS EC2 instance that uses EBS storage as its local drive.  The web app runs on an Apache/Tomcat server, handles uploaded files in local storage and uses a MySQL database, all on this local drive.  Does AWS guarantee the integrity and availability of EBS data or should I back it up to S3?
  If so, how do I do that? I need to have daily incremental backups (i.e. I can only afford to loose recent transactions/files performed today).
  Note: I am not worried about human caused errors (accidental deletes, etc.) rather system crashes, underlying service failure, etc.
  Thanks.. </p>
