I created an Exact image backup of my primary drive to a second hard drive. That went fine. Then I created a daily incremental backup to the same file, but it creats a new file in the second drive with the same name. Now I have 4 backup's in 4 days. The 2nd, third, and fourth files are certainly not only changes to the original backup, because they are 600-800 mb's each. With this system, I will run out of room on my 160gig hard drive. What is it I need to do to put all incremental backups within the first backup created, thus creating an up to date backup of my primary drive on a daily basis. Keng I know this must seem very elementary to most of you.
