Abstract

The embodiment of the invention discloses a file redundancy removal method for terminal equipment, the terminal equipment and a storage medium, which are used for eliminating redundant files generated when a user uses the terminal equipment and shortening the time required by a redundancy removal process. The method comprises the steps of obtaining a write request; according to the write request, calculating a foreground hash value and metadata of a write page through a foreground; acquiring idle information of the terminal equipment, and determining a triggering opportunity; under the condition that the triggering opportunity is met, calculating a file with the same foreground hash value, and outputting index node information of the file with the same foreground hash value; calculating a background hash value according to the foreground hash value, the metadata and the index node information; and performing redundancy removal on the same files in the background hash value by using a hard link method.

Description

technical field [0001] The present application relates to the field of terminal equipment, and in particular, to a file de-redundancy method, terminal equipment and storage medium related to terminal equipment. Background technique [0002] According to the survey, an in-depth user of a smartphone will generate redundant files of a considerable size. At present, most of the smartphone de-duplication methods are carried out in the background. These de-duplication programs will detect the existing redundant files through a full scan of the smartphone, and then provide them to the user for elimination. [0003] Today, smartphones encrypt files for security reasons. Since Android (Android) 7.0, most smartphones support the FBE (File-based Encryption, file-level encryption) method. The advantage of this encryption method is that one file has one key. If the full-disk scanning method is used to de-duplicate the same files, each file in the smartphone needs to be scanned, and a d...
