Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] The embodiment of the present invention provides a multi-node backup method. The multi-node backup method is applied to a server cluster system. The servers in the server cluster system include M working nodes that work normally and N backup nodes that do not perform any work. Both M and N are positive integers, and N is less than M, and the specific values ​​of M and N can be determined according to actual needs; the above-mentioned multi-node backup me...

Abstract

The invention discloses a multi-node backup method and a multi-node backup device and is applied to a server cluster system. A server of the server cluster system comprises M work nodes working normally and N standby nodes carrying out no work, wherein the M and the N are positive integers, and the N is smaller than the M. The multi-node backup method comprises steps that, when any work node is in fault and can not work, the node generating the fault is determined to be the fault work node; a standby node is selected as a replacement node according to preset priority corresponding to each standby node and the fault work node; the replacement node is utilized to replace the fault work node, and the replacement node accomplishes work of the fault work node. According to the multi-node backup method and the multi-node backup device, the server has relatively low backup redundancy, investment cost is relatively less, and management can be easily carried out.

Description

technical field [0001] The present invention relates to the technical field of server software, and more specifically, to a multi-node backup method and device. Background technique [0002] A server, also called a server, is a device that provides computing services. Since the server needs to respond to the service request and process it, generally speaking, the server should have the ability to undertake and guarantee the service. And as the business volume that the server needs to complete increases, the backup of the server becomes more and more important. [0003] In the prior art, a dual-machine fault-tolerant server cluster system is usually adopted, that is, two servers plus one or more storage arrays realize dual-machine hot backup, peer-to-peer dual-machine and dual-machine double-cabinet working modes. machine environment. However, for industries that urgently need to provide high-availability services, there are many key businesses that need to achieve high av...
