title: Pentaho data integration logging backup
body: <p>I wanted to have Kettle logging backup per day. By default Kettle writes its log into standard output. I'm able to write logging into files and also sets the logging level. But it'll write to a single file only. I'm using Pentaho data integration stable release 4.2.0</p>
  
  <p>Is there a way to backup last days log? (Like using log4j in Java)</p>
