Embodiment 1

[0092] According to an embodiment of the present invention, a method for storing and retrieving files for a service node is proposed; in this method, the service node is not a node in the cloud database, and the node server has a node in the cloud database with read and write permissions on the cloud database . Such as figure 1 shown, including:

[0093] Step 101: The service node receives the first service request from the user, and scans the files contained in the preset area;

[0094] Wherein, the first service request is specifically a device cleaning request, the preset area is specifically a recycle bin in the device, and each file includes files in various formats such as documents, forms, and pictures.

[0095] Step 102: the business node determines the sensitive files among the scanned files, and sends the sensitive files to the node server for the node server to save the sensitive files to the cloud database;

[0096] According to the embodiment of the present inv...

Embodiment 2

[0112] According to an embodiment of the present invention, a kind of file storage and retrieving method for node server is proposed; In this method, node server is the node in the cloud database with cloud database read and write authority; figure 2 shown, including:

[0113] Step 201: the node server receives the sensitive file from the business node, generates a file record according to the received sensitive file, and saves the generated file record to the cloud database;

[0114] According to the embodiment of the present invention, in step 201, the node server receives the sensitive file from the service node, specifically: the node server receives the file storage request from the service node, and the file storage request includes the sensitive file and the device identification of the device where the service node is located.

[0115] Correspondingly, in step 201, the file record is generated according to the received sensitive file, specifically: the node server enc...

Embodiment 3

[0137] According to an embodiment of the present invention, a method for storing and retrieving files is proposed; in this method, the business node is not a node in the cloud database, and the node server has a node in the cloud database with read and write permissions in the cloud database; as image 3 shown, including:

[0138] Step 301: The service node receives the first service request from the user, and scans the files contained in the preset area;

[0139] Wherein, the first service request is specifically a device cleaning request, the preset area is specifically a recycle bin in the device, and each file includes files in various formats such as documents, forms, and pictures.

[0140] Step 302: the service node determines sensitive files among the scanned files, and sends the sensitive files to the node server;

[0141] In this step, the business node determines the sensitive files in the scanned files and sends the sensitive files to the node server, which is the ...

Abstract

The invention discloses a file storage and retrieval method and device, and belongs to the technical field of cloud databases. The method comprises the following steps that: a service node receives afirst service request from a user, scans each file contained in a preset area, determines a sensitive file from the files and sends the sensitive file to a node server; the node server generates a file record according to the sensitive file and stores the file record in a cloud database; when the service node receives a second service request from a user, a file retrieval request is generated andthe file retrieval request is sent to the node server; the node server searches a cloud database for a matched file record according to the file description information contained in the second service request, generates a finding result and returns the finding result to the service node; and the service node displays the received finding result to the user. According to the method and the device,the sensitive file is stored in the cloud database, so that the sensitive file can be traced and found in the cloud database, the safety of the file can be effectively guaranteed, and a user can still directly use the sensitive file without affecting the working efficiency after finding the sensitive file.

Description

technical field [0001] The present invention relates to the technical field of big data, in particular to a file storage and retrieval method and device. Background technique [0002] In today's networked, modernized and intelligentized world, computers have become an indispensable part of people's work. Documents with tens of thousands of words, reports full of numbers, various meaningful pictures, etc., through computer processing, not only improves work efficiency, but also helps to improve the quality of each document itself. However, in the process of using computers to work, people will also accidentally delete some important files due to carelessness, and they will be completely deleted during garbage cleaning; thus affecting the progress of the work, especially the files with complicated content, they must be recreated. It takes a lot of time and effort. In order to solve this problem, the industry has proposed cloud storage, which saves files deleted by users to t...
