We recommend that you regularly check key elements of your Data Archive system. This process has traditionally been called the daily health check even though most of the checks do not need to be performed daily. These checks allow you to identify and resolve potential problems before they become serious. You can also determine how your Data Archive system operates under normal conditions and establish a baseline to use when you set up automatic monitoring.
