The invention relates to the field of wireless communication, and provides a method for backing up a multi-service database. The method comprises the following steps of: reading dataset type, user name and password corresponding to the service database from a configuration file, and automatically creating a link character string for linking the database; after the link character string is successfully linked to the service database, accessing the data dictionary of the service database, and reading all data table names created by a user from the data dictionary; matching the user name and the password according to the read data table names, acquiring the authority of a backup data table, calling a backup method of the database, and providing various backup options on an interface; and after the user selects a backup option, starting backing up the data table. The invention also provides a method and a device for recovering the multi-service database, and a device for backing up the multi-service database. According to the method and the device provided by the invention, each service can be prevented from providing backup/recovery scripts, and the coupling property of a platform can be reduced.
