Metadata organization method, system, storage medium and backup method, retrieval method
A data backup and metadata technology, which is applied to the redundancy in the operation for data error detection and response error generation, etc. It can solve the problem of inability to achieve a good separation effect, independent modularization of metadata, affecting advanced backup functions, etc. problems, to optimize the backup process, realize modular management, and achieve the effect of fast retrieval

Embodiment 1
[0050] In one embodiment, as figure 1 As shown, a metadata organization method is provided for use in the server side, and the method includes:
[0051] S1. Send a target file request and a target folder request to the client.
[0052] It is worth noting that the receiving situation on the server side depends on the scanning situation on the client side, because before scanning the client side, the content stored on the client side is unpredictable, it may only contain the target file, it may only contain the target folder, or both. Contains target files and target folders.
[0053] S2. Receive the first metadata of the client and the absolute path of the file, wherein the first metadata includes file name, file type, file creation time, file modification time and file size; the first metadata is the target file. The first metadata and the first metadata of the target folder; the file absolute path is the file absolute path of the target file and the file absolute path of th...
Embodiment 2
[0078] like Figure 4 As shown, in one embodiment, a metadata organization method is provided for use in a client, including the steps:
[0079] S100. Receive a target file request and a target folder request from the server.
[0080] S200. According to the target file request and the target folder request, scan the client by means of breadth traversal to obtain the first metadata and the absolute file path.
[0081] It is worth noting that the breadth traversal refers to starting from a vertex V0 and traversing the wider area around it radially, specifically, such as figure 2 As shown, the breadth traversal starts from vertex V0 (ie C: / ), and scans V0 to V8 in sequence according to the number size, where floater represents folders, such as floater_1, floater_2 and floater_3; file represents files; the numbers in file brackets Represents the size of file data, such as file_1(100), file_2(100), file_3(50), file_4(100), and file_5(150). In addition, compared with deep traver...
Embodiment 3
[0085] like Figure 5 As shown, in one embodiment, a metadata organization system is provided for use in the server side, and the system includes:
[0086] The first sending module 1001 is used to send a target file request and a target folder request to the client;
[0087]The first receiving module 1002 is configured to receive the first metadata of the client and the absolute path of the file, wherein the first metadata includes file name, file type, file creation time, file modification time and file size; the first metadata includes file name, file type, file creation time, file modification time and file size; The metadata is the first metadata of the target file and the first metadata of the target folder; the file absolute path is the file absolute path of the target file and the file absolute path of the target folder;
[0088] The unique identification acquisition module 1003 is used to acquire the MD5 value of the target file;
[0089] a first update module 1004, ...
