Abstract

The invention relates to a data processing system including at least two disk emulators operating in parallel. Each of the at least two disk emulators emulates a disk subsystem and is associated with a respective file in a file system for any data stored on a physical disk. The data processing system further includes a de-duplicator for de-duplicating the data stored in the respective files associated with the at least two disk emulators. The de-duplicator operates in parallel to the disk emulators and is associated with an additional disk emulator emulating an additional disk subsystem. The additional disk emulator is associated with an additional file in a file system configured to store data shared between the respective disk subsystems emulated by the at least two disk emulators.
