Embodiment Construction

[0062] The core of the present invention is that when the working machine sends data, the working machine compresses the data to be synchronized and adds a corresponding check code and transmits it to the backup machine; correspondingly, when the backup machine receives data in the present invention, it decompresses the The synchronization data with the check code added, and judge whether the synchronization data is successful according to the check code of the data, and save the synchronization data after the judgment is yes. It reduces the time to synchronize data between two machines, avoids data loss when two machines synchronize data, and increases the stability of the system.

[0063] During specific implementation, when the working machine sends data, the working machine that sends the data extracts the summary of the data to be synchronized and uses the summary as the check code of the data to be synchronized, and then compresses the data to be synchronized into a data ...

Abstract

The present invention discloses a double-computer thermo-backing up data synchronization method and device. Said method includes working machine compressing he treated synchronization data, and adding and transmitting relevant check code to backing up unit; backing up unit decompressing synchronization data from working machine with added check code, according to said synchronization data check code judging whether said synchronization data being complete, and if it is then saving said synchronization data. The present invention effectively reduces double-computer synchro data time, avoids double-computer synchronization data lose, increase systematical stability.

Description

technical field [0001] The present invention relates to dual-system hot backup technology, and more specifically, the present invention relates to a method and device for realizing data synchronization between dual-system hot backup servers. Background technique [0002] Dual-machine hot backup technology is a high fault-tolerant technology combining software and hardware. Usually, a dual-system hot backup system is composed of two servers and an external shared disk array or a disk array card (Redundant Array of Independent Disks, RAID) existing in the two servers and corresponding dual-system hot backup software. It is the working machine, and the other server is the backup machine. When the system is in normal operation, the working machine provides support for the information system, and the backup machine monitors the operation of the working machine (the working machine also monitors whether the backup machine is normal). [0003] In practical applications, the dual-m...
