#CMT# #/CMT# The device has a file server (12) provided with a server data memory (16) and a primary file system (18), where files stored in the memory are kept in the system. A primary hierarchic memory management part (20) divides the files into primary activity groups (22, 24, 26) with different hierarchical levels based on primary activity criteria and keeps the files of the group (26) having the lowest level in a secondary data system (38) of a downstream data memory device (42). The files to be copied are combined into structured container objects (50-1 to 50-3), which are stored in the system (38). #CMT#USE : #/CMT# Data processing device. #CMT#ADVANTAGE : #/CMT# The files to be copied are combined into the structured container objects, which are stored in the secondary system, thus eliminating the need for managing entire individual data, and hence secondary data system is managed and operated in an efficient and simple manner, and a problem of slowing down caused by the huge volume of data is eliminated. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a data processing device with a file server. 12 : File server 16 : Server data memory 18 : Primary file system 20 : Primary hierarchic memory management part 22, 24, 26 : Primary activity groups 38 : Secondary data system 42 : Data memory device 50-1 to 50-3 : Container objects. |
