Abstract

The invention discloses a method and system for data management. The method includes calculating one or more of the following eigenvalues: eigenvalues ​​of first data in a first format, and eigenvalues ​​of one or more data in a second format into which said first data can be converted, The feature value uniquely represents an arrangement feature of at least a portion of bits of the data in a specific format; and in response to one of the calculated one or more feature values ​​being the same as the stored feature value corresponding to the second data, storing One of the first data and the second data. Through the embodiments of the present invention, data files from the same source data can be deduplicated.

Description

technical field [0001] The present invention relates to a method and system for data management, and more particularly, to a data de-duplication method and system capable of deduplication of data files in storage from the same source data . Background technique [0002] With the continuous increase of the amount of data stored and the emergence of cloud storage, it is increasingly necessary to manage data in the storage space reasonably to meet the growing demand for data storage. Sometimes, users may store many identical or substantially identical data in the process of storing data. Therefore, data deduplication technology is proposed to eliminate redundant data in order to improve storage utilization and reduce the burden of network data transmission. [0003] For example, known data deduplication techniques generally remove redundant data files with identical bits by comparing the contents of two data files bit by bit. However, for two data files with different binary ...
