Method for safeguarding the continuous safety operation of computers

The invention relates to a method for protesting computer system and data security which can keep computer operating continuously and securely. It uses computer as main part, and calls five modules to keep computer operating continuously and securely. It comprises: first module as system fast recovery module, second module as system backup recovery module, third module as data network backup recovery module, forth module as computer block-unblock module, fifth module as arbitrating module. It demands users to input legal account number when the computer is started, then it calls block-unblock module to block the locking of the hard disk; when computer system is out-of-order, arbitrating module adopts fast recovery model to recover the system, if it failures, it adopts backup recovery model and auto recovers user's data from network so that it can keep computer operating continuously and securely.
