today, for the first time, i tested AY GHOST, it is a tool that could backup your drive, maybe i am not good at description. so i would like to quote the official introduction of AY GHOST. sorry for that.
AYGHOST is a very simple and effective hard drive imaging/cloning software. It allows you to create an exact disk image for complete system backup and disk cloning providing the most comprehensive data protection. The disk backup file contains the exact copy of a hard disk, including all the computer data, operating system, and programs. AYGHOST also streamlines the desktop deployment process by allowing you to multicast a hard drive to a network of computers. Based on the exclusive Snapshot disk imaging technology, AYGHOST allows you to create a system disk backup file or multicast a hard drive with AyRecovery snapshots included.
