title: Cronjob on Amazon EC2 Deleted?
body: <p>I had a cronjob set up to run a php script daily, which went well for about a month. Today, I realized it didn't run the script so I opened up the crontab. The crontab is completely empty - what happened?</p>
  
  <p>I don't know too much about cronjobs, but as far as I understand, they do not delete themselves if the server is reset. How can I make sure cronjobs are always running and that it doesnt get deleted?</p>
