My backup is scheduled for once a week, in Norton 360. When it backs up, it is sending the same information to my external backup, time after time. How do I get it to just send new information and not the same stuff over and over again? (I have a 4 TB external drive that is currently FULL ! Sorry, but I don't buy that many iTunes songs!!
I know it's got to be something simple that I have overlooked, but I'm just not figuring this out. Can someone help?
