title: Cleanup the /var/lib/jenkins/caches folder
body: <p>my jenkins caches(<code>var/lib/jenkins/caches</code>) folder is more that 8gb, I have to perform a backup of my Jenkins home directory.</p>
  
  <p>Is it safe to delete entire files <code>/var/lib/jenkins/caches/*</code> or cleanup the <code>/var/lib/jenkins/caches folder</code>? </p>
  
  <p>Will it affect my existing jobs?</p>
