On the contrary, with the computer system software and application software for larger and more complex, computer software failure is rising, Mainly from the failure of a computer hard drive system, save a hard drive, also save a set of computer systems. Computer information systems data is the most important resources, but the data caused by various reasons frequently lost or damaged, its loss unpredictable, and th
