I have been using windows 8.1 genuine for last 6 months. Now i want to backup my system to some DVDs. When i start backup it estimates the backup size as 55 GB or something. Which means it is going to backup not only the system but also the soft-wares i have installed to the PC. Is there any solution to backup only my system. (i can remember one of my friends did it and it took about 16 GB. I am using a lenovo G510 PC).
