The present application is applicable to the field of data processing technologies and provides a datasheet backup method, a device, an electronic apparatus and a medium. The method comprises: upon receiving first backup configuration information or a repeat backup instruction input by a user, reading and retrieving all second backup configuration information including a backup identifier; searching for and locating, according to backup source table information and backup target table information, a backup source table and a backup target table corresponding thereto from a database, reading backup field information in the second backup configuration information and copying data corresponding to the backup field information in the backup source table to the backup target table; determining if copying of a backup field is successful; and if the determination result is that the copying of the backup field is successful, deleting the backup identifier in the second backup configuration information. Use of the method obviates the need to repeatedly back up datasheets even in an adverse backup environment, thereby significantly increasing the efficiency of datasheet back up.
