Abstract:
1. An image forming apparatus comprising: an interface configured to establish a connection with an external storage in which address book data is stored in a backup process; an internal storage configured to store, in a restore process, address book data read from the external storage; an interface control unit configured to make, in a restore process, the interface enter a state in which the external storage can be unmounted in response to an instruction to unmount the external storage when the address book data has been stored in the internal storage; and a deletion control unit configured to delete, in the restore process, the address book data stored in the internal storage in response to entering the state, wherein the deletion control unit deletes, in the restore process, the address book data by determining whether or not the address book data is the same as second address book data stored in the external storage and deleting the address book data from the internal storage when the address book data is the same as the second address book data, and wherein the interface control unit determines whether or not the external storage is unmounted when the address book data has been deleted and terminates the restore process upon determining that the external storage has been unmounted.
