graphing disk utilization

When we check the button ‘Store on Disk’ in the graphing option, I am wondering if there is some limit and auto clean up that the system does, so that the graphs don’t consume the entire disk after awhile? Or do we need to do the clean up ourselves with some script.

If we need to do it, how do we clean without deleting recent history?

In our case, we can’t store these graph remotely as they turned on for individual customers to view locally for themselves.
