title: How to dump all databases with ArangoDB
body: <p>I have ArangoDB running locally with databases, collections, data and graphs from several different projects in it. I'd like to back up everything so I can rebuild my system. I know how to do a backup of a single database, but because I have a bunch I'm hoping to do this in one shot.</p>
  
  <p>Essentially, I'm looking for the ArangoDB equivalent of</p>
  
  <pre><code>mysqldump -u root -p --all-databases &gt; alldb.sql
  </code></pre>
  
  <p>Obviously the ArangoDB equivalent of </p>
  
  <pre><code>mysql -u root -p &lt; alldb.sql
  </code></pre>
  
  <p>Would be good to know too.</p>
