A method of operating a data processing system, in particular a micro-computer, comprises a backup process in which a copy of every change made to a storage medium is recorded as the change occurs. Write operations for writing data to the storage medium are each preceded by a backup write operation to backup storage means, successive backup write operations being controlled so as to be stored as a sequential list in the backups storage means in the form of location blocks and data blocks to avoid the overwriting occurring in the storage medium. These backup write operations are executed at the level of the basic input/output system (BIOS) of the microcomputer in such a manner that normal use of the computer is unaffected. The method also includes a restore process in which bad sectors of a destination storage device are avoided by translating the file allocation table (FAT) and directories of the original data. |
