Method and device for storing file

Abstract

The invention discloses a file storage method. N storage units are arranged in a storage device, wherein N is a signless integral no less than 2. The method comprises: storing the metadata of a stored file and/or content data of common files into M storage units, wherein M is a signless integral less than N; and storing the content data of uncommon files into the residual N-M storage unit. The invention also provides a file storage device, comprising N storage units, wherein M storage units are used for storing the metadata of the stored file and/or the content data of common files; and the residual N-M storage units are used for storing uncommon files. According to the invention, the response time for finding file content is shortened, the file access speed and efficiency are improved, and the integral cost of storage equipment is effectively reduced.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a file storage method and device. Background technique [0002] Information data storage is a necessary condition for the realization of centralized information management, and it is an important link in the information management system. With the development of society and the advancement of science and technology, various organizations need to store and manage more and more information data for their own development, and more and more files are created in various application information systems. Many information data and files need to be preserved for future reference. Users also rarely delete saved data and documents, making it difficult to access older files. Facing the ever-increasing amount of information data, adopting a scientific and reasonable storage method is conducive to the centralized management and retrieval of a large amount of information. [0003] For th...

[0006] However, when accessing infrequently used data, the access method is much less efficient than accessing commonly used data

Under this storage structure, the file search time is proportional to the storage space that the system needs to search, because the data volume of infrequently used files is 2-3 times or more than that of commonly used files, and the corresponding search and access time The time will increase by
