title: Cleanup Nexus Repository for old cached components
body: <p>I have a nexus server and while monitoring it I found out that nexus is using 500 GB in Server. I was shocked to see that as I had an Idea that size of our artifacts would be around 30 GB. And I was right, checking on DB I found that size used was about 26 GB.</p>
  <p>While trying to figure out I found out a setting Allow Redeploy in release repositories. So what is happening is whenever a redeploy the new artifact is replacing the old one but the old one is not getting deleted. It is cached somewhere. How can I delete that cached data to clear out some space?</p>
