Is there a way to add a date into a report for seeing disk space usage? I have a report that shows me all the Disk Space that is Used on our Servers....now my supervisor wants me to see if we can do a comparison from week to week. So far I have not had any luck with this. Is there a way to add a date range into the report I have and generate one report with last weeks dates and another report with this weeks dates and information?
