id="introduction">Introduction</h2> <p>Elasticsearch initially began as a custom search engine. These days, it has gone above and beyond that singular role as it's part of <em>log aggregation stacks</em>, <em>security monitoring</em>, and even as a <em>datastore for performing exploratory analysis</em>.</p> <p>Indices in Elasticsearch are where the data is stored, and there are often times when these indices need to be transported from one cluster to another. Perhaps we just need a safe backup before moving data to another cluster or upgrading versions. Elasticdump is a tool that helps in facilitating this backup and restore operation.</p> <blockquote> <p><em>Elasticdump</em> is a tool made to move and save Elasticsearch indices.</p> </blockquote> <p>In this guide, we'll take a look at how to use <em>Elasticdump</em> and how to create and move indices between clusters on your local computer.</p> <div class="alert alert-note"> <div class="flex"> <div class="flex-shrink-0 mr-3"> <img src="/assets/images/icon-information-circle-solid.svg" class="icon" aria-hidden="true"/> </div> <div class="w-full"> <p><strong>Note:</strong> To follow this tutorial, you need to have <a href="/docker-a-high-level-introduction" target="_blank">docker installed</a>, as well as <a href="/how-to-install-node-js-on-ubuntu" target="_blank">NPM</a>.</p> </div> </div> </div> <h2 id="whatiselasticdumpandwhyuseit">What Is Elasticdump, and Why Use It?</h2> <p>Those familiar with Elasticsearch would know of its <em>"Snapshot and Restore"</em> feature to facilitate these operations. Yes, it is indeed a smart feature that helps back up individual indices or an entire cluster. While exploring that option for a small number of indices or clusters, you may find that using the <em>"Snapshot and Restore"</em> feature could be an overkill. This is even more pronounced when there's no system to incrementally take snapshots.</p> <p>This is where Elasticdump can help - it's a lightweight tool that can move and save indices with a remote repository required by Elasticsearch's <em>"Snapshot and Restore"</em>.</p> <div data-nosnippet="" id="ad-snigel-1"><div class=" my-4 flex justify-center" style="min-height:250px"><div id="adngin-incontent1-0"></div></div></div><p>Here's what Elasticdump can do:</p> <ul> <li>Copy the indices from one cluster to the other</li> <li>Dump indices to flat files</li> <li>Back up indices & mappings</li> <li>Restore indices across different versions of Elasticsearch</li> <li>Multielasticdump that comes along with Elasticdump can export multiple indices in parallel</li> </ul> <h2 id="settingupelasticdump">Setting up Elasticdump</h2> <h3 id="installation">Installation</h3> <p>Elasticdump is a Node package and it can be directly downloaded from <a href="https://www.npmjs.com/package/elasticdump" target="_blank" rel="noopener nofollow">NPM</a>.

If you have an Elasticsearch cluster running already, <u><a href="#elasticdumpinaction">you may skip this step</a></u>.</p> <p>For others, the following commands will spin up an Elasticsearch container for you. Make sure you have Docker or Docker Desktop installed and running on your machine. You can download your suitable installer from <a href="https://www.docker.com/products/docker-desktop" target="_blank" rel="noopener nofollow">here</a>.</p> <p>Once your Docker server is up and running, let's create a directory, which will contain the volume to hold Elasticsearch's data.

We have also assigned an environment variable (<code>-e</code> flag) stating that it is going to be a single node setup.</p> <p>Then, we attach the volume (<code>-v</code> flag) to the directory created in the previous setup, mapped to the data directory inside the container, in which the data will be stored.</p> <p>Finally, the <code>--name</code> flag is to give a nice name to the container while the <code>-d</code> flag is to make the container run in the background, and <code>docker.elastic.co/elasticsearch/elasticsearch:7.13.0</code> is the name of the image.</p> <p>We'll copy data from this Elasticsearch cluster to another cluster, using Elasticdump.
