ABSTRACT:
The invention provides an information processing apparatus and a data processing method for the information processing apparatus wherein software processing is performed using a program and/or data and which are improved in that the reliability of data can be raised flexibly in accordance with a degree of reliability required for the data even after operation of a system is started without using a specific backup hardware construction. The information processing apparatus is of the type wherein software processing is performed using data stored in a storage apparatus and includes a first storage apparatus for storing original data, a second storage apparatus for storing preliminary data which can back up the original data and can be used similarly to the original data in the software processing, and a data duplicating registration section for storing a relation between the original data and the preliminary data into a storage table.
