[0001] The present invention relates to the technical field of data synchronization, and in particular to a server data synchronization method and system. Background Art

[0002] In today's digital age, server data synchronization plays a vital role in many fields, such as corporate office, cloud computing services, distributed systems, etc. With the continuous expansion and globalization of corporate business, data needs to be frequently synchronized between servers in different geographical locations to ensure data consistency and availability. At the same time, users have increasingly higher requirements for the real-time and accuracy of data. Any data inconsistency may lead to serious consequences such as business interruption and wrong decision-making. Existing data synchronization methods lack an effective mechanism when dealing with users' temporary modifications and urgent synchronization needs for files. When a user modifies a file on a local server, the remote server may not be able to obtain the modification information in time, and other users cannot know which data has been modified, and thus cannot know whether the data they are accessing is the latest data. Therefore, it is necessary to provide a server data synchronization method and system to solve the above problems. Summary of the Invention

[0023] As a further solution of the present invention: the method also includes: before generating data synchronization information and synchronization mark stamp, the network bandwidth occupancy rate of the three-level transmission channel is also measured.

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0054] like Figure 1 As shown, an embodiment of the present invention provides a server data synchronization method, the method comprising the following steps:

[0055] S100, receiving file update information sent by the user terminal, the local server updates the corresponding file according to the file update information, and generates modification tracking information;

[0056] S200, generating data synchronization information and a synchronization marker based on the file update information and the modification tracking information, wherein the data synchronization information and the synchronization marker correspond to each other one-to-one, and the synchronization marker includes a data storage location and modification tracking information;

[0057] S300, sending the synchronization marker to the remote server via the primary transmission channel, and sending the data synchronization information to the remote server via the tertiary transmission channel;

[0058] S400, receiving modification tracking information, so that a modification mark is inserted into the corresponding file in the remote server;

[0059] S500: Receive a file access instruction, access the corresponding file, receive a modification mark click instruction, and generate a pop-up window to determine whether urgent synchronization is required;

[0060] S600, receiving an emergency synchronization confirmation instruction, so that the corresponding data synchronization information is sent to the remote server through the secondary transmission channel;

[0061] S700: Receive data synchronization information, so that the corresponding file in the remote server is synchronously updated. After the synchronous update, the corresponding synchronization mark stamp is deleted.

[0062] It should be noted that the traditional server data synchronization method mainly adopts a simple full data synchronization, that is, the entire data set is regularly copied from the source server to the target server. Although this method is simple to implement, it consumes a large amount of network bandwidth and server resources. Especially when the amount of data is large, the synchronization process will become very slow, seriously affecting the performance and response speed of the system. In addition, the existing data synchronization method lacks an effective mechanism when dealing with users' temporary modifications to files and urgent synchronization needs. When a user modifies a file on a near-end server, the remote server may not be able to obtain the modification information in time, and other users cannot know which data has been modified, and thus cannot know whether the data they are accessing is the latest data. The embodiments of the present invention are intended to solve the above problems.

[0063] In an embodiment of the present invention, it is first necessary to construct three transmission channels between servers, namely, a primary transmission channel, a secondary transmission channel, and a tertiary transmission channel, with corresponding transmission speeds decreasing. The primary transmission channel is used for metadata transmission, adopts the UDP protocol to implement lightweight broadcasting, and sets a 128-bit transmission sequence number to ensure sequential consistency; the secondary transmission channel is used for emergency data synchronization, reserves a bandwidth guarantee mechanism, dynamically allocates at least 30% of bandwidth resources, and implements TLS1.3 encrypted transmission; the tertiary transmission channel is used for routine data synchronization, adopts breakpoint resume technology, sets every 2MB as a transmission unit, enables incremental compression technology, and performs LZ4 real-time compression on text files. When a user sends file update information to the proximal server, the proximal server will update the corresponding file according to the file update information, and automatically generate modification tracking information, which reflects the area where the file has been modified. The near-end server will then generate data synchronization information and a synchronization mark stamp based on the file update information and modification tracking information. One piece of data synchronization information corresponds to one synchronization mark stamp, and the synchronization mark stamp includes the data storage location and modification tracking information. The embodiment of the present invention accurately generates data synchronization information and synchronization mark stamps, and only transmits necessary data, which greatly reduces network bandwidth and server resource consumption, and improves the overall performance and resource utilization of the system. The synchronization mark stamp is then sent to the remote server through the first-level transmission channel, and the data synchronization information is sent to the remote server through the third-level transmission channel. It is easy to understand that the synchronization mark stamp arrives at the remote server before the data synchronization information. When the remote server receives the synchronization mark stamp, it will insert a modification mark into the corresponding file in the remote server according to the modification tracking information. In this way, other users can clearly know which data has been modified and whether the data they are accessing is the latest data. Other users can access the corresponding file by inputting the file access instruction. If there is a modification mark in the file, it means that the file is not the latest. When the user clicks the modification mark, it is equivalent to inputting the modification mark click instruction. At this time, a pop-up window will be generated asking whether emergency synchronization is required. When the user clicks yes, an emergency synchronization confirmation instruction will be input. At this time, the corresponding data synchronization information will be sent to the remote server through the secondary transmission channel, so that the data required by the user can be urgently synchronized. After the remote server receives the data synchronization information, it will synchronize the corresponding file on the remote server. After the synchronization update, the corresponding synchronization mark stamp will be deleted, and the corresponding modification mark will no longer exist. In this way, when the user has an urgent synchronization need, the emergency synchronization process can be triggered through a simple operation, so that the data synchronization information can be quickly sent to the remote server through the secondary transmission channel, and the file synchronization update can be completed in time, which improves the user experience and ensures the continuity and real-time performance of the business.

[0064] like Figure 2 As shown, as a preferred embodiment of the present invention, the step of generating modification tracking information specifically includes:

[0065] S101, initialize the Git repository for the directory where the file is located on the server, add the file to the repository and commit the last version;

[0066] S102, set up a post-commit hook script in the Git repository, and the script will be automatically executed when the file is updated;

[0067] S103, in the hook script, use the Git command to obtain the difference file between the current version and the previous version, parse the difference file, extract the modified file name and modification range information, and determine the modification tracking information.

[0068] To obtain change tracking information, the present embodiment leverages the features of version control systems (such as Git) to record incremental file information (diffs) for each file modification. Modified parts can be determined by analyzing the diff information. Specifically, a Git repository is initialized on the server for the directory containing the files to be tracked. The files are added to the repository and the previous version is committed. A post-commit hook script is then set up in the Git repository. This script automatically executes when a file is updated. Within the hook script, Git commands (such as git diff HEAD^HEAD--filename) are used to obtain the difference (diff information) between the current and previous versions. The diff file is parsed to extract the modified file names and modification range information, thereby determining the change tracking information. For example, the display may read "lines 10-15 of file example.txt were modified." This accurately reflects the modification range and supports complex file operations (such as insertion, deletion, and modification). Git itself has powerful version management capabilities.

[0069] like Figure 3 As shown, as a preferred embodiment of the present invention, the step of receiving modification tracking information and inserting a modification mark into the corresponding file in the remote server specifically includes:

[0070] S401, receiving modification tracking information, and determining all data modification areas in the corresponding file according to the modification tracking information;

[0071] S402: inserting a modification mark in each data modification area, wherein the modification mark has a link pop-up window triggering function, and each modification mark corresponds to a synchronization mark stamp.

[0072] In an embodiment of the present invention, the modification tracking information has clearly expressed which parts of the file have been modified, and all data modification areas in the corresponding file can be easily obtained. Then, a modification mark will be inserted in each data modification area. The modification mark has a link pop-up window triggering function. Clicking on any modification mark will trigger a pop-up window.

[0073] like Figure 4 As shown, as a preferred embodiment of the present invention, the steps of receiving a file access instruction, accessing the corresponding file, receiving a modification mark click instruction, and generating a pop-up window of whether emergency synchronization is required specifically include:

[0074] S501, receiving a file access instruction, retrieving synchronization setting information of the accessing user, accessing the corresponding file, and determining whether a modification mark exists in the file;

[0075] S502, when there is a modification mark and the synchronization setting information is automatic emergency synchronization, the corresponding data synchronization information is sent to the remote server through the secondary transmission channel;

[0076] S503: When there is a modification mark and the synchronization setting information is urgent synchronization on demand, a modification mark click instruction is received and a pop-up window is generated to ask whether urgent synchronization is required.

[0077] In an embodiment of the present invention, the user can also customize the emergency synchronization mode and select automatic emergency synchronization or demand emergency synchronization. When there is a modification mark in the file accessed by the user, and the synchronization setting information is automatic emergency synchronization, the corresponding data synchronization information is directly sent to the remote server through the secondary transmission channel. When there is a modification mark in the file accessed by the user, and the synchronization setting information is demand emergency synchronization, if the user checks the file and finds that the part of the content he needs has not been modified and there is no modification mark, there is no need for emergency synchronization; if the user finds that there is a modification mark on the content he needs, he will enter the modification mark click instruction, and a pop-up window will be generated to ask whether emergency synchronization is needed.

[0078] As a preferred embodiment of the present invention, before generating data synchronization information and synchronization mark stamps, the network bandwidth occupancy rate of the tertiary transmission channel will also be measured. When the network bandwidth occupancy rate is lower than the occupancy threshold, it means that the rate of the tertiary transmission channel is faster and equivalent to the rate of the secondary transmission channel. At this time, only data synchronization information is generated, and no synchronization mark stamp is generated, thereby avoiding the execution of useless programs.

[0090] The modification tracking information unit is used in the hook script to use Git commands to obtain the difference file between the current version and the previous version, parse the difference file, extract the modified file name and modification range information, and determine the modification tracking information.
