Best backup software for windows?

What is the best backup software for Windows? I want something that can restore the image of a hard drive very fast. I tried Acronis True Image, it works fine, but it can take hours to restore. The last time, it took 9 hours to restore a 50GB hard disk image. Backup does not take so long. Usually, only 10-15 minutes. I do not know why it takes so long to restore.

Any program that can recover quickly?
