I am running a MacPro, Quad-core, 2007 with 16GBs of memory. Each and every time I run SuperDuper, there are always files to copy. I just ran it 3 times in a row, without doing anything on the computer, and there were 74 files copied twice and 70 copies on the third attempt. I thought that if I made a SmartCopy back up, it was an exact copy. And if so, why would it need to copy files again when I have literally done nothing on the computer? Shouldn't there be zero files copied? Thanks.
