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....
