Description

Data backup method, device and storage medium Technical Field

[0001] The present invention relates to the fields of edge computing and network communications, and in particular to a data backup method, device, and storage medium. Background Art

[0002] As digitalization becomes increasingly important in the manufacturing industry, more and more data is being collected and stored to support various applications such as process tracking, equipment monitoring, predictive maintenance, and AI-based analysis and optimization. With the development of IoT technology, more and more data is now collected through sensors and on-site lightweight IoT gateways or IoT edge devices, and then transmitted to application servers.

[0003] Occasional disconnections between the IoT gateway and the server are inevitable due to updates to the operating system / application / library on the server, unexpected service interruptions on the server, network outages due to cable problems or configuration changes, network reconstruction, etc. To continue collecting important data and avoid data loss during server disconnections, IoT gateways are usually designed to temporarily cache collected data and upload the cached data immediately after the server connection is restored.

[0004] IoT gateways with large data storage capacity are essential to avoid data loss caused by prolonged disconnection from the server, especially when large amounts of data need to be collected. For example, if more than one sensor is connected to the gateway and data collection is frequent, the gateway must be robust. Since IoT gateways in most IoT applications are designed to be low-cost, low-function, and deployed on a large scale, the need for industrial-grade large data storage capacity significantly increases costs. Furthermore, it is difficult to implement a redundant storage system, such as a dual-disk backup system, to ensure the security of cached data on the gateway.

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0029] IoT gateways with large data storage capacity are essential to avoid data loss caused by prolonged disconnection from the server, especially when large amounts of data need to be collected. For example, when more than one sensor is connected to the gateway and the data collection frequency is high. Since IoT gateways in most IoT applications are designed to be low-cost, low-function, and deployed on a large scale, the need for industrial-grade large data storage capacity will significantly increase costs.

[0030] Therefore, an embodiment of the present invention provides a more optimized data backup method, apparatus and storage medium. Among them, the method includes: the edge backup device obtains the data backup request sent by the gateway, and evaluates the backup request based on the backup request and the data processing capability of the backup device; if the backup request is met, the backup data is received and saved; according to the recovery request of the gateway, the backup data is sent to the gateway or application server according to the guidance of the request. The gateway confirms with the application server whether the application server can communicate with the edge backup device; if so, the backup data is directed to be sent to the application server; otherwise, it is directed to be sent to the gateway, and then sent to the application server by the gateway. The technical solution in the embodiment of the present invention can back up data after evaluating the backup request in combination with the processing capability of the edge backup device, can flexibly handle backup needs, and at the same time reduce the cost of deploying a large number of backup devices, and realize a more flexible backup network structure.

[0031] Figure 1 is a schematic diagram of the architecture of a data backup network according to an embodiment of the present invention. As shown in Figure 1, the network may include:

[0032] Edge backup device 101 is a computer-like device primarily consisting of a CPU, memory, storage disks, a network interface card, and more. It can be a server, PC, or IoT gateway-like device. It is capable of connecting to a network, receiving data from other devices, transmitting data to other devices, and storing data on one or more storage disks. An edge backup device can be a general-purpose, lightweight IoT backup device, independent of any specific IT application. There may be more than one edge backup device in a network. An edge backup device can be a standalone device solely responsible for data backup, or it can be a standard IoT gateway with large storage capacity that supports both IoT data collection services (acting as an IoT gateway) and data backup services (acting as an edge backup device). This means that each gateway can be an edge backup device and can easily share storage with each other if it has more processing power and storage space than its own tasks require.

[0033] Gateway 102 can act as a data transfer point, sending data from edge devices to a centralized data center for dispatch to application servers, or forwarding server data to edge devices. When communication between the gateway and the application server is interrupted, it requests a cached data backup from the edge backup device. When restoring data, it acts as a bridge, asking the application server whether it can directly receive backup data from the edge backup device and requesting the edge backup device to retrieve the backup data.

[0034] The application server 103 can communicate directly with the gateway or the edge backup device. After verifying the communication possibility with the edge backup device, it can directly receive the backup book stored therein.

[0035] FIG2 is a flow chart of a data backup method 200 deployed on an edge backup device according to an embodiment of the present invention. As shown in FIG2 , the method 200 may include:

[0036] In the edge backup device information acquisition step S201 , the data processing capability of the edge backup device is acquired.

[0037] In the backup request acquisition step S202, a data backup request sent by the gateway is acquired; wherein the data backup request includes data backup requirement information.

[0038] Specifically, there are two ways a gateway can send a backup request to an edge backup device. First, a list of specific network addresses for edge backup devices can be reserved and placed in each gateway's configuration file. When a gateway requires backup services, it can send a request message to each edge backup device address to locate it within the network. Second, since every edge device or gateway can provide data backup services as an edge backup device, the gateway can broadcast the request message across the network and select a single edge backup device from all responding devices.

[0039] The backup request evaluation step S203 includes: evaluating the data backup request based on the data backup requirement information and the data processing capability of the edge backup device; and sending data backup request confirmation information to the gateway if the edge backup device can process the data backup request.

[0040] In one embodiment, the data processing capabilities of the edge backup device include: computing power, network bandwidth, storage space and / or ongoing backup tasks;

[0041] The data backup requirement information includes: storage space requirement, communication requirement and / or data priority.

[0042] Specifically, the storage space requirement and the communication requirement may be a sampling frequency, a size of data sampled each time, and / or a time required for backup, etc.

[0043] Specifically, data backup requests from other edge devices or gateways can be evaluated based on the capabilities of the edge backup device, such as processing power, network bandwidth, storage space, ongoing backup services, and request information. After accepting the request from the IoT gateway, it will receive and store all data from the gateway. The request message may include the gateway's identity information and specific requirements, such as device ID, security check token, storage requirements, such as the sample size of the collected data, collection frequency, storage capacity required per minute, communication requirements, such as TCP, UDP, whether ACK is required, and even the priority of the data, similar to QoS (Quality of Services). After evaluation, if the storage requirements can be well met, the edge backup device will send a confirmation message to the gateway.

[0044] The backup data receiving step S204 is to receive the backup data sent by the gateway after obtaining the data backup request confirmation information, and save the backup data to the edge backup device.

[0045] Specifically, the gateway sends the collected data to the edge backup device. After receiving the data from the gateway, the edge backup device will not attempt to interpret the content or structure of the data and will simply store the data as is.

[0046] In the backup and recovery request acquisition step S205, a backup and recovery request sent by the gateway is acquired.

[0047] In the backup data sending step S206 , the backup data stored in the edge backup device is sent to the gateway or application server according to the backup recovery request.

[0048] In one embodiment, the backup and recovery request includes backup and recovery guiding information; the backup and recovery guiding information is used to guide the backup data to be sent to the gateway or application server.

[0049] Specifically, when the connection between the gateway and the application server is restored, if the application server does not support the edge backup device-related services, the gateway will attempt to retrieve the backup data from the edge backup device and send it to the application server. The gateway can send a query message to the application server to inquire whether the application server supports the edge backup device service. If the server confirms the message, the gateway will notify the edge backup device to transfer the backup data directly to the application server instead of returning the data to the gateway.

[0057] Backup data receiving step S305: acquiring the backup data sent by the edge backup device.

[0058] In one embodiment, before the backup recovery request sending step S304, the method further includes: a backup recovery guidance inquiry step S306, including: sending backup recovery query information to the application server, inquiring whether the application server can communicate with the edge backup device, obtaining the backup recovery confirmation information of the application server in response to the backup recovery query information, and generating a backup recovery request based on the backup recovery confirmation information.

[0059] In one embodiment, the backup and recovery request includes: backup and recovery guidance information, which is used to guide the backup data to be sent to the gateway or application server; if the gateway receives the backup and recovery confirmation information, it generates a backup and recovery request containing backup and recovery guidance information that guides the backup data to be sent to the application server; otherwise, it generates a backup and recovery request containing backup and recovery guidance information that guides the backup data to be sent to the gateway.

[0060] Specifically, when the connection between the gateway and the application server is restored, if the application server does not support the edge backup device-related services, the gateway will attempt to retrieve the backup data from the edge backup device and send it to the application server. The gateway can send a query message to the application server to inquire whether the application server supports the edge backup device service. If the server confirms the message, the gateway will notify the edge backup device to transfer the backup data directly to the application server instead of returning the data to the gateway.
