I've just installed and registered Acronis True Image Home 2009. It's working great. Can I install and use this software on a second computer? I have the two computers connected to a DSL combination wireless modem and router (one with a network cable and the other wireless). How can I use ATIH 2009 to back up both computers? (I have a USB dock and a couple of big, empty hard drives that I intend to use back up to).
