[0006] 2. Shared storage media is expensive and subject to geographical restrictions
The two servers are connected through a small computer system interface (SCSI, Small Computer System Interface) and a shared storage medium, which makes the hardware cost very expensive. At the same time, because the distance supported by SCSI is very short, the storage location of the two servers is limited.
[0007] 3. Storage space must be provided for the shared storage medium

Embodiment Construction

[0056] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] The dual-machine backup system in the present invention can be realized by using two servers of any type, and it is only necessary to add interfaces for communicating with each other on the two servers, such as serial ports and network ports. In order to ensure reliable communication, multiple communication interfaces can be set to ensure that when one communication interface fails, other communication interfaces can continue to realize the communication between the two servers.

[0058] figure 2 It is a system composition diagram of the present invention to realize dual-machine backup, as figure 2 As shown, the system mainly includes:

[0059] Server 1 and Server 2: At the same time, the two servers are respectively the active server and the standby server, and regularly send status notification messages to each other, and...

Abstract

The present invention discloses a double-computer backing up implementation method, which contains respectively increasing communicating interface on two servers of realizing double-computer backing up, through signalling exchange of main server and standby server to realize two servers main using and standby state switch, through main using server synchronous transmitting service data to standby server to realize two servers data synchronization. The present invention also discloses double-computer backing up system including main using server, standby server and client-side. The present invention provided is free from operation system restriction, capable of operation in different kinds of operation system platform, by software to realize without increasing the hardware cost. The present invention provided system is free from server hard ware restriction, any two kinds server capable of consisting of double-computer standby system with fine compatibility, available single machine system capable of convenient updating to double-computer standby system without sharing storage medium and saving space.

Description

technical field [0001] The invention relates to the field of dual-machine backup, in particular to a method and system for realizing dual-machine backup. Background technique [0002] At present, in order to ensure long-term stable operation of carrier-class servers, redundant designs are provided for some of its components, such as power supply redundancy, network card redundancy, and hard disk mirroring. However, if a key component of the server fails, such as a central processing unit (CPU) failure, memory failure, motherboard failure, etc., the entire server will stop running and cannot continue to provide services, which will seriously affect the operation of the entire system, for example: causing business interruption, etc. [0003] In order for one server to fail, another server can replace it to provide services in a short time. Microsoft's Windows 2000 Advanced Server operating system provides cluster services. Through this service, Windows 2000 Advanced Server o...
