title: Redis as a queue - Configuration review
body: <p>I need to setup a Redis DB (2.8), which i suppose to use as a queue, which means that it's must be fully persistent (no message can be missed). </p>
  
  <p>I'm pretty new with Redis, and i would like a get a review for my configuration:</p>
  
  <ul>
  <li>I want to use both AOF and RDB persistence models, while <code>always</code> will be selected as <code>appendfsync</code> policy. According to their decontamination, always is not recommended, but i must select this option as i use Redis as a queue, and i can't endure any massages missing.</li>
  <li>I would like a create a Master-Slave-Slave cluster using Sentinel with automatic failover.</li>
  <li>Redis service will be automatically started after server boot.</li>
  </ul>
  
  <p>Any kind of comments and suggestions will be great. The administration point of view is more important to me (persistence, backup, restore, high availability, etc). </p>
