From the Terabyte website.... The Technician License Grants additional rights that will allow a Service Company to use Image for DOS, Image for Linux, or Image for Windows on client computers. Each Technician will require this license to use each Full-Use copy of the software. The Full-Use License Rights and Technician License Add-On Rights are purchased separately. Does something like this exist for the Acronis Line of Software? If not I have no choice but to purchase the Terabyte stuff.
