A chip card retaining mechanism for retaining a chip card (40) mounted in an electronic device is provided. The electronic device includes a housing (10) having a battery compartment (14) defined therein. The chip card retaining mechanism includes a locking member (30). The locking member is securely mounted on the receiving portion. The locking member and a surface of the housing cooperatively form a receiving cavity therebetween for receiving the chip card therein and locking the chip card in the receiving cavity. A first end of the locking member and a surface of the housing cooperatively form an opening for inserting the chip card.

A remote online information back-up comprises a local computing system and a remote computing system. The local computing system includes a local disk and a local device driver. The local device driver is responsive to requests from a local application executing on the local computing system, for selectively processing calls to the local disk or to a remote disk for backup of data resident on the local disk. The remote computing system includes the remote disk and a remote device driver. The remote device driver is responsive to calls from either the local device driver or calls from a remote application executing on the remote computing system, wherein calls from the local device driver are processed to perform backup operations to the remote disk of data resident on the local computing system.
