Abstract

The Computer Image Replication System automatically replicates a customer'"'"'s computer system image, including all of the customer'"'"'s data, programs, device drivers, program preferences, personalizations, and file directory structures on a new computer system. The Computer Image Replication System is part of a Data Shadowing System which comprises a memory module that is connected to a monitored computer system via an existing communication medium, such as an input/output port, to store the shadowed data. The memory module includes a memory device for data storage, as well as software, including a control software component that is automatically installed on the monitored computer system when the memory module is first connected to the monitored computer system, as well as associated module software for maintaining a record of the data stored on the memory device and controlling the operation of the memory device.
