Embodiment Construction

[0025] The specific implementation manners of the backup method, device and system of the multi-application system provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] The backup method of the multi-application system provided by the embodiment of the present invention, such as figure 1 As shown, the specific process includes the following steps:

[0027] S101. When the first virtual machine system in each virtual machine system of the standby host needs to be switched to the active state, obtain the resource configuration of the first virtual machine system in the active state, and each virtual machine system is respectively associated with each application system one-to-one correspondence;

[0028] S102. According to the resource configuration of the first virtual machine system in the active state, determine whether the currently available resources of the backup host can satisfy the sw...

Abstract

The invention discloses a backup method, device and system of a multi-application system. Multiple virtual machine systems which correspond to multiple application systems in one-to-one mode are arranged in a backup host. When the virtual machine systems need switching to a main use state, whether existing available resources of the backup host meet switching of the virtual machine systems or not is confirmed, if yes, the virtual machine systems are controlled to switch, if no, when other virtual machine systems in the backup host is confirmed to be capable of being switched to a backup state from the main use state, the other virtual machine system are controlled to complete switching, when the existing available resources of the backup host are confirmed to be capable of meeting switching of the virtual machine systems which need switching to the main use state, the virtual machine systems are controlled to switch. Due to the fact that backup systems are established in the multiple application systems by using all virtual machine systems of one backup host, system source utilization rate of the backup host is improved. Meanwhile, main and backup switching of all the virtual machine systems of the backup host is controlled uniformly, so that main and backup switching speed is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a backup method, device and system for a multi-application system. Background technique [0002] At present, for application systems, an emergency backup mechanism is generally established. According to the importance of the application system, a disaster recovery system with real-time data synchronization can be established, or an asynchronous and synchronous backup system can be adopted to provide emergency backup protection. [0003] In the implementation of backup technology, in order to ensure that when the backup system is switched to the active state, there are enough resources to bear the business pressure in the active state, so only a separate backup system can be used to deploy the backup mechanism for the application system. The backup system can have the same resource capability as the application system, but 95% or more of the resources of the backup system a...
