I tried the command line but I kept on getting an error "Error logging report to file" error. I was successfull in greating the report using the GUI.
Unfortunately it only gives me the data at the top folder level as selected in the backup spesification. What we are running into is that some of the middleware applications are creating temporary files in folders that are 4 or 5 levels deep. The files were not large in size but there were just thousands of them.
One of our web application servers had over 800K session files in it's temp folder but it was 5 levels deep.
