Abstract

An embodiment of the invention discloses a data storage method. The method comprises generating and storing data file independent index files; generating index key information according to the independent index files, wherein the index key information comprises file identification information and part index information of the independent index files; combining and storing the index key information and the data files. By means of the method and device, the independent index files can be searched from the data files reversely, and reverse data analysis and reverse storage resource recovery are achieved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a data storage method and device. Background technique [0002] In the existing data storage technology, independent index files are usually used to assist the management of data files. For example, data files need to be saved to disk. The traditional method is to create an independent and complete independent index file, write data, and then use the independent index file. Obtain data files and analyze them; when deleting data, you also need to find the independent index file first, and then reclaim the storage resources occupied by the data according to the data index. [0003] The existing technical defect of managing data files through independent index files is: when the independent index file of the data file cannot be found or the content of the independent index file is wrong due to various reasons, the storage resources occupied by the data file cannot be rec...
