Abstract

The invention discloses a server dual hot backup system, and belongs to the technical field of backup. The system comprises a first server and a second server; the first server comprises a first heartbeat release module, a first heartbeat subscription module and a first master-salve switching module, and the second server comprises a second heartbeat release module, a second heartbeat subscription module and a second master-salve switching module; when the first server is a master server, the first heartbeat release module is used for sending a first heartbeat signal; the second master-salve switching module is used for switching the second server into the master server when the times of not receiving the first heartbeat signal exceed a threshold; when the second server is the master server, the second heartbeat release module is used for sending a second heartbeat signal; the first heartbeat subscription module is used for obtaining the first heartbeat signal and the second heartbeat signal; and the first master-salve switching module is used for switching the first server into the master server when the server startup time of the first heartbeat signal is later than the server startup time of the second heartbeat signal.

Description

technical field [0001] The invention relates to the technical field of backup, in particular to a server dual-machine hot backup system. Background technique [0002] Data communication systems usually require the system to have high reliability, and no matter whether it encounters a sudden failure or active maintenance, it will not affect the normal operation of the system. To improve reliability and maintainability, disaster backup and recovery is a must. For systems with high reliability requirements, the best backup solution is dual-machine hot backup. [0003] There are generally two methods for dual-machine hot backup. One is a disk array method, and the other is a pure software method. The pure software method means that during the operation of the system, there are two servers loaded with exactly the same system and data, and at the same time, they are kept in sync through communication cables. The currently working server is called the primary server, and the oth...
