title: Elasticsearch Curator
body: <p>I am using ElasticSearch Version 1.7.2. I want to take a snapshot with help of the curator. I followed a link get to know that it gives me an incremental snapshot but I didn't get any incremental snapshot of my index.</p>
  
  <p>I have 1 index <code>test</code> having 50,000 docs. I have taken a snapshot of that index. After inserting 100,000 docs in the same index, I again took a snapshot of that index. But when I check it, it's showing me the same data in both my snapshots.</p>
  
  <p>What's the difference between those? I don't think it is incremental in any way. Please help me out.</p>
  
  <p>PS: I only want to backup the remaining 100,000, not the whole data.</p>
