title: Heroku PGBackups add-ons: Why choose anything but the free one month retention option?
body: <p>I'm looking into database backup options for our Heroku rails app, and it looks like the free <a href="https://addons.heroku.com/pgbackups" rel="noreferrer">PGBackups add-ons</a> would work well.</p>
  
  <p>However, I'm confused by the options. They are:</p>
  
  <pre><code>Basic - 2 manual back-ups
  Plus - 7 manual back-ups
  Auto One Week - 7 automatic daily and 2 manual
  Auto One Month - 7 automatic daily, 5 automatic weekly, 10 manual
  </code></pre>
  
  <p>They're all free. I must be missing something here because I don't see why you'd choose any but the last option. Is there a downside that I'm missing? What are the pros and cons I'm supposed to be weighing here?</p>
