Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] In order to realize data restoration without stopping business, a main computer and at least one backup computer are set in the computer system of the present invention. The host computer can be the main processor, or it can be a computer dedicated to data backup. Please refer to FIG. 1 , which is a schematic structural diagram of the computer system of the present invention for realizing data recovery. It includes a main computer 11 and several backup computers 12 . The main computer can be connected to the backup computer 12 through a dedicated line, or can be connected to the backup computer 12 through a network (such as the Internet). The main computer 11 and the backup computer 12 can be located in the same place or in different places. However, the network speed and network quality will directly affect the quality of subsequent data recovery, so the b...

Abstract

The invention discloses a data restoring method within duplicating course and restoring course, which comprises the following steps: (1) the main computer divides the duplicated file into several data blocks through computer, which stores the data block on at least one duplicating computer; (2) when the relative file data changes, the main computer sends the data block of changed data on the duplicated computer; (3) when the detected data of main computer is damaged, it affirms the damaged data block and acquires the duplicated data block in the duplicated computer to restore the data; when the accident stops the operation, the main computer selects one duplicated computer as new main computer to finish system conversion. The invention can accomplish the data duplicating and restoring without stopping business, which minimizes the data damage scope and restoring cost to reach the neglect degree.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data recovery method. Background technique [0002] Because computers have high-speed data processing capabilities and large-capacity storage capabilities, computers are widely used in various fields of production and life, such as communications, transportation, banking, etc., and many computer systems need to be in a state of continuous operation in order to ensure the entire normal operation of the system. For example: Once the switch server of the telecommunications department is shut down, many user terminals will not be able to communicate normally. Once the information processing system of the bank card organization is shut down, it will also cause a large number of cardholders and merchants to be unable to conduct bank card business. Bring inconvenience, therefore need existing computer system to have better system security function, especially when main processor breaks down,...
