INSTRUCTIONS: [Technical field to which the invention pertains] The present invention is directed to a computer (four) system and a data multi-thread system and method, and more particularly to a system having a plurality of client computers and servers. In the data mirror backup and _ system, the customer's basic input and exit system (Basic 〇utpui System, BI〇s) in the operation of the client computer and the data backup on the ship H t are restored. A system and method for performing a disk image backup and recovery of a system and data on a client computer.仃/, [Prior Art] ... With the wide application of information technology, more and more lines # began to use computers to enter the government, control and do the job. At the same time, with the popularity of personal computers, people can realize a variety of electric education, pre-preparation, games and entertainment at home. = This computer has played a pivotal role in improving social productivity and human living standards. However, with the increase in the use of computers, the failure or file failure, the possibility of loss of the first material, the greater the birth, and for the majority of computer practitioners and the brain industry group Before or after the job file system, what method can be used to back up the useful data in the disk sector of the computer system in a timely and effective manner, and the computer system fails or fails? After that, it is very important to quickly and reliably recover the computer system from the fault state to: normal grief or complete and accurate recovery of the lost gambling secret (4). 200825712 Nowadays, the most popular computer data backup and recovery methods are mostly implemented by the image tool (imageTGGl). The image tool Wei is to back up and restore all the contents of the computer disk (4), and it will judge each disk. Fan (four) file system type, and according to different job system structure to practice useful user poor material for image backup, and when necessary, mirror or restore these data. In fact, all the data mirroring and recovery _ processing methods are also the same, which can save the backup and recovery operations between %, but also save the space required for backup data. At present, in the enterprise's regional network system environment, disk image mirroring and recovery of client computer operations and related poor materials is a very important part of the enterprise computer management solution, which is computer data. The basis of management. The known system and poor material disk image backup and recovery method needs to be backed up and restored by each client data backup, recovery and recovery process and recovery of the brain (4) system, and data The backup and recovery program will process the heart (4) and read the (4) 'customer, and process the processed image. When the data is restored, the client prepares the mirror to take the mirror in the mirror. Kawasaki's capital _=^ is first written from the back of the shirt to the corresponding disk sector of the client computer. The analytic complex method also has the following problems and defects. · /, k 200825712 1. Must be in Each client computer runs a client data backup and recovery program with a huge amount of data capacity, and each client computer needs to process or parse the data to be backed up or to be restored, so on the client side. In the case of a large number of computers, the efficiency of data backup and recovery operations will be lower. 2. The data backup and recovery program running on each client computer requires its own _ environment and (4) system support, which will lead to the complexity of the entire data backup and recovery system. , : Because the main function of the tributary backup and recovery system runs on the client, the operating state of the system cannot be known in time at the server and the server, thus the performance of system management and error processing is relatively low.曰 [Summary of the Invention] In order to solve the problems and defects in the above-mentioned prior art, the object of the present invention is to provide a disk image backup and recovery system and method for computer system data, using a plurality of client computers and servos. The data mirroring backup and recovery system uses the basic input and output of each client computer (in the s) to enter the shouting operation _ the new backup of the wipes, each client*, the green and the (4) The image is ready for recovery. Recovery ΐΐ Provides a disk image backup of computer system data and a plurality of client program modules. The basic wheel-in and turn-out system (BIOS) is set in a plurality of client computers. It is used to receive the 200825712 read and write disk request data packet sent by a server, and according to the content of the disk sector structure (DSS) in the read and write disk request data packet to each client computer. The corresponding disk sector performs data read and write operations, and then returns the result of the read and write operations to the server; an analog disk read/write module is set in the server for setting Read and write the disk request packet and read and write the disk. Please read the contents of the disk sector structure and send the read and write disk request packets to each client computer, and then receive each client. The computer returns to the results of the reading, writing and processing, and sends the results of the reading, writing and operation to a broadcast system to process the analysis module; a slot system processing analysis module is set in the mine for receiving The result of the read and write operations sent by the analog disk read/write module, and when the data backup is needed, the data from the disk sector of the client a is read from the data of the forest to the backup and then written into the feeding service. In the case of reading the image slot, when data recovery is required, the image is read from the image broadcast, and the magnetic material of the 'K' is sent to the analog disk read/write module to be stored in the disk sector structure. In the data area; and a mirror slot reading module in the server, the rib performs the reading and writing operations on the mirror job. Go to you~, (the computer-m-material mirror backup and recovery method, The following steps are included: Start a client that needs to enter (four) material backup The basic input wheel of this computer is _ = first ^ in a feeding service ϋ to connect u households, Asia and a data package, ^ ^ each computer receives a request from the server's fine disc 'Q, 5 buy disk The content of the disk sector structure (DSS) in the request packet reads 200825712 t the corresponding disk light data in each terminal computer; (4) __娜结翻__, the ship fine structure = a poor material package Send to the miner; after receiving the data packet, the extractor extracts and processes the data of the disk area, and then writes the processed disk sector data to the mine to find the capital, and the need to start # Material recovery touch number ^, the pre-set is set in the basic input and output system of each computer, connected to #Γ client program, and connected with the ship 11; each client receives the write disk request packet from the feeding device 'According to the write disk request resource _ss (four) capacity, the work in the data area of the disk structure is transferred to the corresponding disk sector in each computer; and will be = domain _ Wei structure deposits - a data packet towel sent to the feeding service to restore with Yuan Cheng tribute. System and method Φ 2 Lin Ming's electric age system (4) disk mirror backup and recovery system, '' towel's disk Wei structure (DSS) content contains: - a disk starting sector number, is an integer, used The starting position of the disk sector; - a fan _ whole = to read or write, the number of disk sectors; - two integers, 0 face shouting silk class Wei two = Tao, district __ write Two == For the result identification, the system contains 〇4, / H trees 30 and 1 two integers '〇 indicates that the operation is successful, indicating that the operation of 200825712 into the disk is +. % take a to 舄 与 恢复 恢复 ' ' ' ' ' ' ' ' ' ' ' ' ' ' _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The fine-grained client-side process, the setting and writing of the network data, and the reading and analysis of the data of the disk sector are all processed and dissolved in the data of the θ complex, two; 'The number of the second-largest computer with no large-scale computer is worse than the situation. The data backup and ra μ can exist in the BIOS of each client computer because each terminal is long. The backup and recovery programs of the client data require the limitations of their respective operating system domains, which greatly reduces the complexity of the entire data preparation and recovery system of the subordinates. , . . 3 Secrets of all bribes and to be restored: New Zealand's handling and analysis of Wang Zuo are in the feeding time: =: 1_ The official client data backup rate.
