Data processing system, data processing apparatus, and computer-readable recording medium having stored therein a data processing program

A data processing apparatus comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• calculate hash information from data and uniquely decides an arrangement destination of the data in the memory according to the calculated hash information;
• move specific data specified as a movement processing target among a plurality of pieces of stored data stored in the memory from the arrangement destination of the specific data to a movement destination;
• and
• write information on a storage position of the movement destination of the specific data to the arrangement destination of the specific data after the movement.

A non-transitory computer-readable recording medium having stored therein a data processing program for causing a computer to execute processing comprising:

• calculating hash information from data and uniquely decides an arrangement destination of the data in a data storage apparatus according to the calculated hash information;
• and
• moving specific data specified as a movement processing target among a plurality of pieces of stored data stored in the data storage apparatus from the arrangement destination of the specific data to a movement destination;
• and
• writing information on a storage position of the movement destination of the specific data to the arrangement destination of the specific data after the movement.
