Abstract

The embodiment of the invention provides a data management device and management method, and a data management system, and relates to the technical field of data management. The data management deviceincludes: a map information generation portion for generating map information on the basis of sector position information for displaying a position where the data is located in a main driver, whereinthe map information displays a sector address as a copy object; a mirror data generation portion for reading sector data at a designated address in the main driver according to the map information, and generating mirror data on the basis of the read sector data; a write-in portion for writing the sector data in a designated address of a large main driver on the basis of the mirror data; and an indication portion for indicating the sector address showed in the mirror data to a duplicator, wherein the duplicator is used for writing data read from the large main driver in a target driver. The data management device can greatly shorten the data reproduction time.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a data management device, a management method and a data management system. Background technique [0002] With the continuous development of computer technology, the storage capacity of various data information is also increasing. The data backup work of drives including hard disks etc. that store a large amount of data information has gradually become heavy and time-consuming. [0003] Especially for the data backup of the drives in the large-scale factory production process, the duplication of the drive data will be a tough job. Specifically, in the process of practical application, large-scale factories or companies usually provide the main drive for storing necessary data information, and the data information required for actual guidance or control of specific production departments is often based on actual needs. From multiple different models of master drives, thi...
