Whatever you do, do not use carbonite business in the enterprise. From an administration standpoint it is a mess. With several hundred mobile users, the web administration interface loads exceptionally slow, and users end up just turning it off. Theres no way to image it out and the users have, for the most part, complete control of there accounts. Carbonite also thinks that the user should setup the files to be backed up and scheduled (no admin). Which means your not saving docs/fav/ or even /user but your going to be saving the entire root of c:. Boom there goes 3tb on your account and a giant bill in the mail.
