Example Embodiment

[0007] like figure 1 As shown, the present invention mainly includes a database 1, a file storage module 2 and a file retrieval module 3,

[0008] Among them, the database 1 has data storage and retrieval functions, and is responsible for saving the data size, storage path, storage location and other information of each small file;

[0009] The file storage module 2 is connected to the database 1, has the functions of file storage location calculation and file storage, is responsible for file storage organizational structure management and small file data storage, and is also responsible for registering file location information in the database 1;

[0010] The file retrieval module 3 is connected to the database 1, has the function of reading file data and creating temporary files, is responsible for reading the file storage location information from the database 1, and reads the file data according to the file storage location information, and creates corresponding temporary ...

Abstract

The invention discloses a method for storing and retrieving massive small files. By adoption of the method, when a user backs up files, the files can be subjected to differential backup according to days, hours and minutes as required, and during the backup, only corresponding file folders are needed to be copied into a backup disk; due to a reasonable design of a file storage organization structure and necessary file merging, even if the files are backed up according to days, the number of the files required to be backed up is 24*60=1440 at most, so that to problem of low copying speed of the massive small files; and when the files are recovered, only the backed up file folders or the files are copied to a corresponding file folder according to names of the backed up file folders and the files. The whole backup and recovery processes are simple and convenient, and the aim of easily and conveniently performing backup and data recovery can be fulfilled while the massive small files can be quickly stored or retrieved.

Description

technical field [0001] The invention relates to a method for storing and retrieving massive small files. Background technique [0002] At present, the storage and retrieval of massive small files is mainly realized by directly storing small files on the disk through a specific file storage directory structure, and recording the storage path of the files through the database. This technology has a disadvantage: in the case of a particularly large number of small files, there are many file storage directories, and the structure is complex, coupled with the slow copying speed of massive files, it is difficult to backup and restore files. The problem to improve this shortcoming lies in: how to ensure the efficiency of storage and retrieval through an effective file storage organization structure in the case of a particularly large number of small files, and to perform differential backup and recovery of massive files. Contents of the invention [0003] The invention provides...
