title: Retention of continuous-export exported artifact history in Kusto
body: <p>How long does Kusto retain history of exported artifacts? So, considering a specific continuous-export entity has been running for several years, what is the oldest export detail that I can get using the following command:-</p>
  
  <pre><code>.show continuous-export ContinuousExportName exported-artifacts
  </code></pre>
  
  <p>The documentation doesn't specifically refer to any specific time period for which this history is retained, so it's not very clear. What is the safe assumption?</p>
