The system comprises two version repository servers installed with general version management software, and is characterized in that: the two version repository servers are connected by heartthrob wires capable of transmitting state information of the corresponding servers; the inside of each version repository server is also provided with a service detection module, a heartthrob detection module and a data synchronization module; the two version repository servers are both provided with a virtual eservice address floating between the two version repository servers; each version repository server is provided with a data synchronization address used for transmitting and receiving data among opposite version servers; and each server comprises a configuration file for recording all information. The system supports multiple kinks of version management software, and not only maintains the advantages of a centralized type version management system, but also overcomes the defects of fault treatment existing in the prior version management system; moreover, the system can also realize the high usability of the software version management system.
