Obviously, the drawings described below are only some embodiments recorded in this application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0020] Figure 1 This is a flowchart of a file backup method based on NFC technology in one embodiment of the present application; Figure 2 This is a structural block diagram of a file backup system based on NFC technology in one embodiment of the present application; Figure 3 This is a structural block diagram of a server in an embodiment of the present application. DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] like Figure 1 As shown, the file backup method based on NFC technology in one embodiment of the present application includes the following steps: Step 1: The client moves close to the NFC tag of the NAS terminal to obtain the address in the NFC tag; In this step, the client generally refers to a terminal that has the ability to initiate HTTPS requests, render H5 pages, and read NFC tags, such as smartphones, tablets, and other devices; A NAS terminal is a terminal device connected to the network with data storage capabilities. The terminal is pre-installed with an NFC tag and is capable of tag reading. At the same time, the terminal also needs to be able to run web services.

[0023] This address is the Web service link URL, which is the LAN access link URL. It is composed of the NAS terminal IP, port, and Web service context information. The link URL information is then written into the NFC tag in the NAS terminal.

[0024] NAS terminal IP is the LAN IP address of the NAS terminal, which is used to access and manage the NAS terminal within the LAN; The designated port is used to carry out data exchange between the client and the NAS terminal; Web service context information is the contextual environment used to encapsulate and process Web requests in Web applications. It contains all HTTP-specific information during the life cycle of the request and is used to manage global settings, shared data, and static resources in Web applications.

[0025] For example, if the NAS terminal IP is 192.168.0.100, the port is 18080, and the Web service context is cloud / index.html, the assembled URL information is: https: / / 192.168.0.100:18080 / cloud / index.html When the NAS terminal is started, it will start the Web service process, set a fixed LAN IP address (i.e., the NAS terminal IP), and listen to a fixed port (port). The fixed port is the port that is included in the Web service link URL.

[0026] Step 2: The client opens the service page of the NAS terminal according to the address; In this step, the client uses a browser to access the Web service link URL obtained from the NFC tag and opens the Web service page provided by the NAS terminal through a direct connection to the LAN.

[0027] The web service page is an H5 page, a web application with richer functions and better user experience, providing a richer interactive experience, suitable for mobile devices, and further facilitating backup operations.

[0028] The H5 page has a file selection input box, which can browse the files stored in the client through a drop-down menu. It can also include a list of uploaded files, an upload file button, a download file button, etc. The file can be a photo, video, document or program code, etc. After selecting the file to be backed up, click Upload to automatically upload it.

[0029] Step 3: Select the local file of the client through the service page to upload, and write it to the local disk of the NAS terminal for storage.

[0030] In this step, the user directly operates the H5 page and selects the client's local files according to the instructions. The Web service will upload the selected local files and eventually back them up to the local disk of the NAS terminal.

[0031] like Figure 2 As shown, an embodiment of the present application discloses a file backup system using the above-mentioned NFC-based file backup method, including a client and a NAS terminal, wherein: The client stores the files to be backed up and is used to open the NAS terminal's web service page and upload the files to be backed up. It has the ability to initiate HTTPS requests, render H5 pages, and read NFC tags, such as mobile phones, tablets, smart watches, and other devices.

[0032] The NFC tag of the NAS terminal stores a URL for opening the web service page, which is used to store the files to be backed up. The terminal is pre-installed with an NFC tag and is enabled for tag reading, and the terminal has the ability to run the web service.

[0033] The client and the NAS terminal are in the same local area network. When the client is close to the NFC tag of the NAS terminal, it can automatically read the Web service link URL stored in the NFC tag and open the corresponding Web service page through the local area network. The file upload and storage can be completed by following the instructions.

[0034] like Figure 3 As shown, a server in an embodiment of the present application includes: a memory 301 and at least one processor 302; The memory 301 stores a computer program, and the at least one processor 302 executes the computer program stored in the memory 301 to implement the above-mentioned file backup method based on NFC technology.

[0035] According to this embodiment, the beneficial effect of using this NFC-based file backup method is that: it is only necessary to bring the client storing the files to be backed up close to the NAS terminal to open the corresponding operation page, and the backup can be completed by selecting the files to be backed up on the operation page. There is no need to install the corresponding APP and set up a complex connection environment, and the operation is simple and convenient.
