Norton backup error

So, Norton says I need to run a backup on my computer, but when I do it runs into an error saying "Some files were not backed up. Please make sure that all other running programs are closed and then try again." The only other program that was running was Norton itself and I still got the error. I have enough memory and I even tried making another backup storage with the same result. If anyone has any ideas, please let me know.
