If you really backed up more than one gigabyte during the last seven days, you'll see the number of whole gigabyte backed up. Otherwise you'll get a "blank" result, indicating that less than one gigabyte has been backed up. This happens, because SQL handles the "bytes" entry and any associated math (like our conversion to gigabyte using /1024/1024/1024  terabyte would be /1024/1024/1024/1024) as an integer without any fractal component. To get a little more precision into our gigabyte conversion, we will have to convert "bytes" into a floating point data type first:
