Problems solved by technology

[0004] In system restoration, it generally involves data backup and recovery operations. These backup data not only occupy a large amount of disk space, but also take a long time for both backup and recovery operations. In the case of increasing data volume Under the circumstances, this method is less and less suitable for the requirements of fast recovery system

Embodiment Construction

[0082] The present invention virtualizes the storage device and uses mapping technology to provide a virtual storage view for the system. All operations of the system on the storage device are performed on the virtual view. After the virtual view is removed, the system restores to the real view, thereby realizing Quick restore of the system. It contains:

[0083] Virtual device control program ⑦: This module is the interface between the user and the storage device virtual layer ⑥, through which the user can control and set other functional modules of the system restoration.

[0084] Storage device virtualization layer ⑥: This module is composed of three sub-modules: the virtual driver ② of the physical storage device, the virtual mapping algorithm ③ and the abstraction layer ④ of the virtual storage device. This module accesses the physical device through the virtual driver ③ of the physical storage device , provides a "synthetic" virtual storage view to the file system throu...

Abstract

A method for quickly restoring computer system includes virtualizing storage unit, utilizing mapping technique to provide a virtual storage view for said system, carrying out all operations of storage unit on said virtual view by said system and restoring said system to be real view after virtual view is removed off in order to realize quick restoration of said system. The device used for realizing said method is also disclosed.

Description

technical field [0001] A method for quickly restoring a computer system belongs to the technical field of computer storage system structures. Background technique [0002] With the gradual improvement of the stability of computer hardware, computer failures are increasingly manifested as soft failures, that is, various failures caused by software. These soft failures are generally caused by harmful code attacks, misoperation or software incompatibility. With the popularity of network applications, harmful code attacks have become the main source of soft faults, seriously affecting the use of computers. Although people have invested a lot of research and development work in computer security, any computer system has loopholes and the possibility of collapse, and it is impossible for people to block all computer loopholes or completely avoid wrong operations. In fact, due to various unavoidable factors such as human error, an absolutely safe system does not exist in reality....
