摘要：
A backup system, apparatus and method to provide a backup of information associated with replaceable devices in an image forming apparatus, such as a color printer. The information may include information representing use of the replaceable devices. The image forming apparatus may include a system memory for storing the replaceable device information. A backup memory may be located on at least one of the replaceable devices to provide a backup of the replaceable device information. The backup memory may allow the replaceable device information to be transferred to another image forming apparatus, for example, when exchanging replaceable devices from a failing apparatus to a replacement apparatus.
