The application system disaster recovery switching method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 sends a trigger instruction of disaster recovery switching to the server 104 according to the disaster recovery switching requirement, the server 104 responds to the trigger instruction, acquires disaster recovery switching configuration information from the corresponding configuration information database, determines an operation module corresponding to a disaster recovery switching task according to the disaster recovery switching configuration information, and calls the operation module to complete the disaster recovery switching task. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In an embodiment, as shown in fig. 2, an application system disaster recovery switching method is provided, which is described by taking the application of the method to the server 104 in fig. 1 as an example, and includes the following steps:

And according to the difference of the disaster backup switching tasks, the corresponding disaster backup switching configuration information is different. The target disaster recovery switching task is a disaster recovery switching task corresponding to the disaster recovery switching requirement of the current terminal 102.
In a specific implementation, the server 104 may start a disaster recovery switching process of the application system according to a trigger instruction of the target disaster recovery switching task sent by the terminal 102. The server 104 may access a configuration information database storing the disaster-backup switching configuration information, and obtain the disaster-backup switching configuration information corresponding to the target disaster-backup switching task from the configuration information database.
