Sonicwall CDPagentservice.exe processor hog

I have the Sonicwall CDP 2440i. And loaded the the CDP agent on the pc's in our office. The CDPagentservice.exe is taking up to 90% of the some of our PC's at startup. This goes on for about 30-40 minutes. I know that it's design is to automatically search for change files and start backing up. Our Sonicwalll contact said to leave the computers on at night, which we don't want to do. Does anyone know how to make this a lower priority in the registry or.........

Any ideas?

Thanks in advance.
