Description

Technical Field

[0001] This application relates to the field of data security transmission technology, and in particular to a file synchronization method, apparatus and electronic device. Background Technology

[0002] One-way optical gateways are deployed between networks of different security levels, enabling unidirectional data transmission from a low-security domain to a high-security domain through a one-way, feedback-free physical transmission environment. The hardware architecture of a one-way optical gateway typically adopts a 2+1 architecture, consisting of an external terminal, an internal terminal, and a one-way isolation component. The one-way isolation component comprises two one-way isolation cards connected by a one-way fiber optic cable. The software architecture consists of network proxy programs and a security engine running on the external and internal terminals. Together, these hardware and software architectures form a secure host, which ultimately provides the one-way data transmission service.

[0003] Since file synchronization is a core function of the unidirectional optical shutter, it supports multiple synchronization methods. Among them, file synchronization using the built-in file transfer protocol is a widely used method, supporting FTP, SMB, and NFS protocols. Although the unidirectional optical shutter device supports clustering, it lacks cluster-based file synchronization functionality. To achieve parallel transmission across multiple devices, multiple unidirectional optical shutter devices are deployed, each configured with a different file synchronization strategy. This results in high costs. Furthermore, deploying multiple unidirectional optical shutter devices leads to uneven data distribution during file synchronization, resulting in a lower file synchronization rate. Summary of the Invention

[0024] The second device is used to synchronize the second files in the subset of the second files to be synchronized in the order of synchronization of the second files to be synchronized.

[0025] In one possible implementation, before determining the synchronization tasks for the first device and the second device from the set of files to be synchronized, the process includes:

[0026] The set of files to be synchronized is stored on a preset server, wherein both the first device and the second device have read and write permissions to the preset server.

Therefore, the above description should not be considered as limiting, but merely as an example of embodiments.

[0049] These and other features of this application will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0050] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application, which have the features described in the claims and are therefore all within the scope of protection defined herein.

[0051] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0052] Specific embodiments of this application are described thereafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0053] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0054] Firstly, to facilitate understanding of this application, a rule loading method provided in this application will be described in detail.

[0055] like Figure 1 The image shows a file synchronization method provided in an embodiment of this application, according to... Figure 1 The illustrated method steps can solve the problems of high cost and low speed in existing file synchronization technologies. Specific steps include S101-S104.

[0056] S101, determine the file information to be synchronized through the first device.

[0057] The file synchronization method provided in this application embodiment is applied to information security protection devices, such as one-way optical shutters. Further, the information security protection device in this application embodiment includes a first device and a second device, wherein the second device can be one or more. The hardware information of the first device and the second device may be the same, but their functions or roles may differ; for example, the first device may be a master device, and the second device a slave device.

[0058] In other words, information security protection equipment can include multiple identical devices, which can be defined and distinguished as a first device and multiple second devices, etc. Of course, in the event of a failure of the current first device, the first device can be stopped from operating, and a second device can be designated as the new first device to continue operating, so as to ensure the normal operation of the information security protection equipment.

[0059] Optionally, the first device is communicatively connected to each file server. When determining the file to be synchronized through the first device, it communicates with each file server to obtain first file information, which includes the first file and its associated file information on each file server. Then, the first device compares the first file information with second file information to obtain the file information to be synchronized, which includes each file to be synchronized and its associated file information. The second file information is obtained and stored from the previous communication with each file server. This second file information is stored on the first device or a file server; this embodiment does not specifically limit its storage location.

[0060] S102, Generate a set of files to be synchronized based on the information of the files to be synchronized.

[0061] After determining the information of the files to be synchronized, a set of files to be synchronized is generated based on the information of the files to be synchronized according to the preset generation rules.

[0062] As one example, Figure 2 A flowchart of a method for generating a set of files to be synchronized based on the information of the files to be synchronized is shown, wherein the specific steps include S201-S204.

[0063] S201, Extract file attributes of the file to be synchronized from the file information to be synchronized.

[0064] S202, determine the synchronization name of the file to be synchronized based on file attributes.

[0065] S203, a first subset of files to be synchronized is determined based on the device information and file name of the first device, and a second subset of files to be synchronized is determined based on the device information and file name of the second device, wherein the device information includes at least the device performance and the device security factor.

[0066] S204, Generate a set of files to be synchronized based on the first subset of files to be synchronized and the second subset of files to be synchronized.

[0067] In practice, the file attributes of the files to be synchronized are extracted from the information of the files to be synchronized. The file attributes include file name, type, update time, etc.

[0068] Next, the synchronization name of each file to be synchronized is determined based on its file attributes. Optionally, when determining the synchronization name of a file to be synchronized based on its file attributes, the synchronization priority, synchronization time, synchronization type, synchronization strategy, and file name of the file to be synchronized are determined based on the file attributes, and the synchronization name of the file to be synchronized is determined based on the synchronization priority, synchronization time, synchronization type, synchronization strategy, and file name.

[0069] For example, a 2-character string represents the synchronization priority level, consisting of two alphanumeric characters ranging from 00 (high priority) to 99 (low priority); a 10-character string represents the synchronization time, which is the order in which files were acquired, ranging from 0000000000 to 9999999999, with the sequence number cycling, meaning it can jump from 9999999999 to 0000000000; a 1-character string represents the synchronization type, including the file synchronization action and result. The file synchronization actions include adding, modifying, deleting, and synchronizing, corresponding to the letters "N", "U", "D", and "B" respectively; the file synchronization results include success, failure, retry, and abort, corresponding to the letters "S", "F", "R", and "A" respectively; and a 2-character string represents the synchronization strategy, which is pre-defined and has a certain correlation with the synchronization priority level. The synchronization name is 000000000000N01file0, which means that the synchronization priority level of the file to be synchronized is 00, which is the highest. Its synchronization time is 0000000000, which means that it is the first file to be identified as the file to be synchronized. Its synchronization type is N, which means new. Its synchronization strategy is 01, which means that it will be synchronized according to the pre-specified strategy. Its own file name is file0.

[0070] After determining the synchronization names of the files to be synchronized, a first subset of files to be synchronized is determined based on the device information and file names of the first device, and a second subset of files to be synchronized is determined based on the device information and file names of the second device. The device information includes at least device performance and device security factor. Optionally, the files to be synchronized for the first and second devices are determined according to the mapping relationship between device performance, device security factor, and synchronization priority level, thus obtaining the first and second subsets of files to be synchronized. For example, files with better device performance and higher device security factor correspond to files with higher synchronization priority, and files with poorer device performance and lower device security factor correspond to files with lower synchronization priority.

[0071] Then, a set of files to be synchronized is generated based on the first subset and the second subset. That is, the first subset includes the first files to be synchronized, and the second subset includes the second files to be synchronized. Furthermore, if there are multiple first files to be synchronized, they are arranged in synchronization order; similarly, if there are multiple second files to be synchronized, they are arranged in synchronization order.

[0072] Optionally, the synchronization order is arranged from highest to lowest according to the synchronization priority level. If the synchronization priority levels are the same, they are arranged from earliest to latest according to the synchronization time, and so on. The synchronization order is generated according to the synchronization priority level, synchronization time, synchronization type, and synchronization strategy.

[0073] S103, determine the synchronization tasks for the first device and the second device from the set of files to be synchronized.

[0074] After generating the set of files to be synchronized, the synchronization tasks for the first and second devices are determined from the set of files. Specifically, the synchronization tasks for the first and second devices can be determined according to the mapping relationship between device performance, device security factor and synchronization priority level.

[0075] Of course, the names of the file subsets to be synchronized corresponding to the first device and the second device can be predetermined. For example, the file subset to be synchronized corresponding to the first device is named "dev1", the file subset to be synchronized corresponding to one second device is named "dev2", and the file subset to be synchronized corresponding to another second device is named "dev3". When generating the file set to be synchronized, the files to be synchronized are stored in the corresponding locations according to the file subset names. Therefore, at the same time as generating the file set to be synchronized, the synchronization tasks of the first device and the second device are generated, that is, the files to be synchronized included in their corresponding file subsets.

[0076] Optionally, both the first and second devices can poll their respective subsets of files to be synchronized according to their corresponding polling cycles to determine whether their subsets include files to be synchronized, thereby determining their synchronization tasks. For example, it can be determined whether the file size of the corresponding subset of files to be synchronized is 0. If it is 0, it is determined that there is no corresponding synchronization task; if it is not 0, it is determined that there is a corresponding synchronization task, that is, the corresponding subset of files to be synchronized includes files to be synchronized.

[0077] It is worth noting that before determining the synchronization tasks for the first and second devices from the set of files to be synchronized, the set of files to be synchronized can be stored on a preset server. Both the first and second devices have read and write permissions on the preset server, thereby avoiding the problem of low file synchronization rate on the first device caused by storing the files on the first device. The preset server can be any one of the file servers.

[0078] S104, use the first and second devices to perform the corresponding synchronization tasks.

[0079] After determining the synchronization tasks for the first device and the second device, the corresponding synchronization tasks are executed using the first device and the second device, respectively. Optionally, when executing the corresponding synchronization tasks using the first device and the second device, the first device synchronizes the first files in the first subset of files to be synchronized in the order of synchronization of the first files to be synchronized, and the second device synchronizes the second files in the second subset of files to be synchronized in the order of synchronization of the second files to be synchronized.

[0080] It is worth noting that when the first and second devices perform their respective synchronization tasks, they can use the usual file communication protocol without the need to set up a special communication protocol, which makes the production and maintenance costs of the information security protection equipment lower.

[0081] This application embodiment generates a set of files to be synchronized using a first device, so that both the first device and the second device can determine and execute the corresponding synchronization tasks from the set of files to be synchronized. This achieves the purpose of parallel synchronous file transmission through the first device and the second device, without incurring additional costs. Furthermore, it can balance the synchronization tasks of the first device and the second device, greatly improving the file synchronization rate.

[0082] In practice, to easily distinguish between files that have already been synchronized and files that are yet to be synchronized, the following can also be executed: Figure 3 The method steps shown Figure 3 The flowchart shown includes S301-S303.

[0083] S301, the first device modifies the synchronization name of the first file to be synchronized based on the synchronization result to obtain the first synchronization result name of each first file to be synchronized.

[0084] S302, the second device modifies the synchronization name of the second file to be synchronized based on the synchronization result, and obtains the second synchronization result name of each second file to be synchronized.

[0085] S303, the first file to be synchronized, which has been modified to the first synchronization result name, and the second file to be synchronized, which has been modified to the second synchronization result name, are stored in a preset location on a preset server.

[0086] Optionally, after executing the corresponding synchronization task using the first device, the synchronization name of the first file to be synchronized is modified based on the synchronization result to obtain the first synchronization result name for each first file to be synchronized. Specifically, the corresponding synchronization type is modified, that is, the file synchronization action is changed to the file synchronization result. For example, after the file to be synchronized 00000000000N01file0 is synchronized, the synchronization name is changed to 000000000000S01file0, indicating that the file has been successfully synchronized.

[0087] Similarly, after performing the corresponding synchronization task using the second device, the synchronization name of the second file to be synchronized is modified based on the synchronization result to obtain the second synchronization result name of each second file to be synchronized.

[0088] Next, the first file to be synchronized, renamed with the first synchronization result name, and the second file to be synchronized, renamed with the second synchronization result name, are stored in a preset location on a preset server. This preset location is used to store synchronization results. For example, a subset of file synchronization results named "dev" is created in the set of files to be synchronized. In this case, the first file to be synchronized, renamed with the first synchronization result name, and the second file to be synchronized, renamed with the second synchronization result name, are stored in this subset of file synchronization results for querying and other processing of the file synchronization results.

[0089] Based on the same inventive concept, the second aspect of this application also provides a file synchronization device corresponding to the file synchronization method. Since the principle of the file synchronization device in this application is similar to that of the file synchronization method described above, the implementation of the file synchronization device can refer to the implementation of the method, and the repeated parts will not be described again.
