I have My Book 4TB and would like to use it as a backup to my two internal HD.  Anyone know of a good way to do this short of purchasing a second My Book?

Welcome to the community. Do you have the information on the My Book or on the Internal drive? If you have the information on the internal drive you can use the Smartware to backup your computer to the My Book.
