Hi there!!

First things first: How are you backing up your files? Are you using Time Machine? Are you Using Smartware? o.o

If you are using Smartware, when you compare the categories on the Home tab (NOT on the backup tab), do the match in nombers except for system? If they do, then the backup was completed.
