title: Does couchbase persist data?
body: <p>I am planning to store data into the couch-base cluster. </p>
  
  <p>I would like to know what will happen if my couch base goes down for the following scenarios:
  [Consider that there were no active transactions happening]</p>
  
  <ol>
  <li>A node goes down from the cluster.(My assumption is after the node is fixed and is up, it will sync up with other nodes, and the data would be there). Also, let me know after it is synced up will there still be any data loss?</li>
  <li>The cluster went down and is fixed and restarted.</li>
  </ol>
  
  <p>Please let me know data persistence analogy for the above scenarios.</p>
