Abstract

The invention provides a disk data processing method and system, a storage medium and electronic equipment. Relates to the technical field of data storage. The method comprises the following steps: receiving a data deletion request for a disk, wherein the data deletion request comprises a to-be-deleted data identifier; based on the to-be-deleted data identifier, determining to-be-deleted data and a storage file type of the to-be-deleted data; the storage file type of the to-be-deleted data is determined through data size information of the to-be-written data in a data writing process; based on the storage file type of the to-be-deleted data, determining a corresponding data deletion mode; and deleting the to-be-deleted data by adopting a data deletion mode corresponding to the storage file type of the to-be-deleted data. According to the invention, the problem that the disk data read-write efficiency is affected due to high disk data redundancy in the prior art can be solved.

Description

technical field [0001] The present disclosure relates to the technical field of data storage, and in particular, to a disk data processing method, a disk data processing device, a computer-readable storage medium, and electronic equipment. Background technique [0002] Disk is the main storage medium of computer, which can store a large amount of binary data by using magnetic recording technology. The data will not be lost even after the disk is powered off, and can be repeatedly erased and written. [0003] In the existing disk data processing process, user uploaded data is usually added to the file. When deleting data, only the mapping relationship between user data address and file is deleted, and the data itself is not deleted. After the user deletes the data, the data on the disk cannot be released in time, resulting in high data redundancy; it further leads to read amplification in the subsequent garbage collection (Garbage Collection, GC) process, which affects the ...
