Problems solved by technology

[0004] However, in a period of time, the amount of data is often huge, especially the bayonet picture data, etc.
In the above method, user participation is required to delete massive data one by one to maintain the life cycle of these massive data, the deletion efficiency is low, and the execution pressure is also high

Abstract

The invention provides a data cleaning method and device, equipment and a storage medium. The method is applied to NAS (Network Attached Storage) equipment, file metadata and directory metadata of each piece of file data in connected cloud storage equipment are stored in the NAS equipment, the file metadata is used for describing the file data, and the directory metadata is used for describing a directory to which the file data belongs. The method comprises the following steps: receiving an expiration time point sent by cloud storage equipment, wherein the expiration time point is sent after the cloud storage device cleans the expiration file data according to a set cleaning period, and the expiration time point refers to the time point for cleaning the expiration file data; clearing the expired file metadata stored in the device according to the expired time point, and clearing the expired directory metadata stored in the device according to the expired time point after clearing the expired file metadata stored in the device is completed. Data cleaning efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a data cleaning method, device and equipment, and a storage medium. Background technique [0002] With the development of network storage technology, more and more security products and security projects also use NAS devices as storage media for security data. Network storage and cloud storage technologies are usually used in combination. For example, the user's file data is stored in the cloud storage system, and the metadata related to the file data is stored in the cluster NAS (Network AttachedStorage: Network Attached Storage), which is responsible for the cluster NAS Data maintenance. Data in the security industry generally has a storage period, and data beyond the storage period needs to be deleted. [0003] In the relevant data cleaning methods, whether it is a NAS device or a cloud storage device, the application layer in the NAS device needs to control and...
