Abstract

The invention discloses a dual-computer hot backup system, and relates to the technical field of backup. The dual-computer hot backup system comprises a master server (1), a slave server (2), a fiber switch (3), a fiber memory (4), and a network switch (5). The master server (1) is connected with the slave server (2) through a heartbeat line (6). Two ends of the fiber switch (3) are connected with the master server (1) and the slave server (2) separately. Two ends of the network switch (5) are connected with the master server (1) and the slave server (2) separately. The fiber switch (3) is connected with the fiber memory (4). The dual-computer hot backup system has advantages of high reliability, high safety and low cost.

Description

technical field [0001] The invention relates to the technical field of backup, in particular to a dual-machine hot backup system. Background technique [0002] The dual-machine hot backup system is a kind of cluster, which refers to a group of mutually independent servers that behave as a single system in the network and are managed in a single mode. This single system as a whole provides high availability of services and network resources. All computers in the cluster have a common name, and services running on any system in the cluster can be used by all network clients. The cluster must be able to coordinate and manage errors and failures of separate nodes, and these failures are not perceived by users, and components can be added transparently to expand its service capabilities. [0003] Dual-machine hot backup technology is a high fault-tolerant application scheme combining software and hardware. The solution is composed of two server systems and an external shared d...
