Hi, is it possible with C++ to backup the whole system image of your PC, meaning not just coping files, but the whole operating system, with all its programs and

files, and to schedule to do it like once a week, including all the drives specified, I have external HD 4TB, Seagate model (which i want to use as destination

drive to store disk image on it). I was unable use to use Windows 7 System Image backup, since this type of HD (Seagate) is new and structured differently.

I am aware of a software like DiskWizard which can be found at

http://www.seagate.com/support/internal-hard-drives/desktop-hard-drives/barracuda-xt/discwizard-master-dl/

which does the job, however, they sell one license for 1 PC, and i would want for more then one PC, like for at least 3.

Get back, thanks in advance.
