Double-computer backup system and backup method

Abstract

The invention discloses a double-computer backup system and a backup method. The system comprises a working server and a backup server, wherein a system monitoring module is used for mutually monitoring through an interior heartbeat cable and another system monitoring module of a local server and also used for detecting the state information of detection resources sent by a resource object module connected with the system monitoring module, sending a warning to a management module of the local server and sending heartbeat information marked to be false to a system monitoring module of an end server through an exterior heartbeat cable when the resource object module is determined to have a fault; the resource object module is used for detecting various resource objects in the resource object module; the management module is used for judging whether the switching operation of double-computer resources needs to be executed or not according to the condition of warning receiving of the management module; and the resource object module is also used for providing various resource objects of the local server. The invention solves the problems of faulty switching of the double-computer resources and fissure faults caused by self faults of double-computer backup at present.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a dual-machine backup system and a backup method. Background technique [0002] Dual-machine backup generally refers to two servers, using shared storage devices (disk array cabinets, storage area network SAN) or no shared storage devices. The two servers can adopt different methods such as mutual backup, master-slave, and parallel. During the working process, the two servers will provide external services with a virtual IP address, and the service request will be sent to one of the servers according to the different working methods. [0003] Such as figure 1 as shown, figure 1 It is a structural diagram of an existing dual-machine backup system, including: an Active server 100 and a Backup server 101, and the Active server 100 and the Backup server 101 coordinate the dual-machines through a heartbeat network 102. Active server 100 includes four parts: system monitorin...
