title: Regular delayed jobs
body: <p>I'm using Delayed Job to manage background work.<br>
  However I have some tasks that need to be executed at regular interval. Every hour, every day or every week for example.</p>
  
  <p>For now, when I execute the task, I create a new one to be executed in one day/week/month.</p>
  
  <p>However I don't really like it. If for any reason, the task isn't completely executed, we don't create the next one and we might lose the execution of the task.</p>
  
  <p>How do you manage that kind of things (with delayed job) in your rails apps to be sure your regular tasks list remains correct ?</p>
