12. Locally restore the configuration data of the application to be processed according to the configuration data of each application in the reference application library.

Specifically, the types of data recovery include rewriting, overwriting, overwriting, updating, and the like. If the configuration data of the application to be processed is empty, the data recovery type is rewrite, and the obtained configuration data of each application in the reference application library is directly used as the configuration data of the application to be processed. If the configuration data of the application to be processed is not empty, further, when the data recovery type is overwrite, the obtained configuration data of each application in the reference application library will overwrite the configuration data of the application to be processed; when the data recovery type is overwrite When writing, the obtained configuration data of each application in the reference application library is compared with the configuration data of the application to be processed, and the missing part of the configuration data of the application to be processed is filled with the configuration data of each application in the reference application library; when When the data recovery type is update, the obtained configuration data of each application in the reference application library is compared with the time stamps of the existing configuration data of the application to be processed, and the configuration data updated with the time stamp is selected as the configuration data of the application to be processed.
