title: Solrcloud Backup & Restore indexed data
body: <p>From last couple of weeks I am using <code>SolrCloud</code> on 3 development server with a single Load Balancer (in future I will extend it to 5 different server for Zookeeper and Solr). My current <code>SolrCloud</code> structure is like below.</p>
  
  <pre><code>Server 1 :  Java + Solr(port 8983) + Zookeeper(port 2181) 
  Server 2 :  Java + Solr(port 8983) + Zookeeper(port 2181)
  Server 3 :  Java + Solr(port 8983) + Zookeeper(port 2181)
  </code></pre>
  
  <p>Here I am able to create SOLR configuration from any server by uploading <code>conf</code> of my collection &amp; <strong>RELOAD</strong> the collection using <code>COLLECITON API</code>, all my SOLR configuration is <strong>syncing</strong> and I am able to index and search my document perfectly. My collection had <strong>1 shard</strong> and <strong>3 replica</strong>, then I split the single shard to two. So basically its a single collection with <strong>3 shard</strong> and <strong>3 replica</strong> now.</p>
  
  <p>So, now I have some questions </p>
  
  <p><strong>Q1)</strong> Is my current structure is <strong>OK</strong> ? or I need to change my current structure ?</p>
  
  <p><strong>Q2)</strong> How can I Backup and Restore my indexed collection data ? </p>
  
  <p><strong>Q3)</strong> What would happen if one of my server closed connection and then I am trying to backup and restore my solr data?</p>
  
  <p>As I have seen the <code>COLLECTION API</code> endpoint to Backup and Restore collection data here at <a href="https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-Backup" rel="nofollow noreferrer">https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-Backup</a> </p>
  
  <p>but couldn't figure out how to set the <code>path/to/my/shard/drive</code> and all that things on those two API endpoint to backup and restore my indexed data. Need help badly</p>
