Embodiment 1

[0018] Embodiment 1 provides a disaster recovery backup method based on cluster technology, please refer to figure 1 , including the following steps:

[0019] Step S100: Obtain a backup task start signal.

[0020] Step S110: Obtain system load data of the disaster recovery server. The system load data of the disaster recovery server includes the number of tasks undertaken, the number of tasks being executed, and network traffic.

[0021] Step S120: Calculate the load weight of the disaster recovery server by using the system load data of the disaster recovery server. In a specific embodiment, the following formula is used to calculate the load weight of the disaster recovery server: In another specific embodiment, system performance parameters of the disaster recovery server are also obtained, and when calculating the load weight of the disaster recovery server, system load data and system performance parameters of the disaster recovery server are considered at the same ti...

Embodiment 2

[0026] Embodiment 2 provides a kind of disaster recovery and backup system based on cluster technology, such as figure 2 As shown, the system includes a device 200 for obtaining the start signal of the backup task, a device 210 for obtaining the system load data of the disaster recovery server, and a device for calculating the load weight of the disaster recovery server by using the system load data of the disaster recovery server 220. The means 230 for screening the disaster recovery servers by using the load weights of the disaster recovery servers, and the means 240 for scheduling the selected disaster recovery servers to perform backup tasks.

Embodiment 3

[0028] Embodiment 3 provides a disaster recovery and backup system based on cluster technology, please refer to image 3 , the system includes a management node 300, a disaster recovery node 310, a storage node 320, and an FC storage switch 330. In the figure, a dotted line represents a network connection line, and a solid line represents a storage connection line. The management node is used to control the operation of the entire system, including the addition and removal of disaster recovery nodes, the addition of storage nodes, and the scheduling of disaster recovery nodes. The disaster recovery node is a disaster recovery server used to specifically perform backup tasks, and the disaster recovery node is controlled and scheduled by the management node to perform specific backup tasks. Storage nodes are used to store backup data. Disaster recovery nodes and storage nodes can be expanded arbitrarily according to demand.

Abstract

A method for disaster recovery backup based on cluster technologies comprises the steps that an initial signal of a backup task is acquired; system load data of disaster backup servers is acquired; load weights of the disaster backup servers are computed according to the system load data of the disaster backup servers; the disaster backup server is screened according to the load weights of the disaster backup servers; and the screened disaster backup server is dispatched to execute the backup task. The cluster technologies are adopted, and a uniform management platform is used to manage all the disaster backup servers; performance of all the disaster backup servers can be monitored in real time; the load weights are computed according to performance monitoring data; the disaster backup server with the minimum load weight is selected automatically to execute the dispatching task; and load unbalance is avoided. As a whole, processing efficiency of disaster backup tasks and the resource use rate of the whole system are increased; the disaster backup servers and storage resources can be extended freely according to actual demands; and uniform management and control are achieved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a cluster technology-based disaster recovery backup method and system. Background technique [0002] Backup refers to the process of copying all or part of the data set from the hard disk or array of the application host to other storage media in order to prevent data loss caused by system operation errors or system failures. The existing backup system is mainly based on an all-in-one computer, and the data of multiple computers is backed up through one backup server. Traditional disaster recovery and backup systems are basically single-server models, that is, one server is installed with a set of disaster recovery software and operates independently. When backup resources are insufficient, resources can be expanded by adding backup servers. The newly added backup server runs independently of the server that has been put into use before, and there is no connection betwe...
