Any downtime can lead to serious consequences, including significant economic losses and service interruptions. Therefore, high availability has become a critical consideration in system design. As a common solution to ensure high availability of systems, hot backup is becoming increasingly prominent. Its core principle is to synchronize one or more backup systems in real time to a state close to that of the primary system, so that it can quickly take over when the primary system fails to ensure uninterrupted operation of the system.

[0003] However, in actual applications, the implementation of hot backup systems for nodes is not smooth sailing and faces many challenges. First, the configuration and management of hot backup nodes is extremely complex. It requires detailed settings and coordination of multiple levels such as hardware, software, and network, which places high demands on the professional knowledge and experience of technicians. Secondly, hot backup systems require additional hardware and software resources to support the operation of backup systems, which undoubtedly greatly increases costs. Enterprises not only need to purchase additional hardware facilities such as servers and storage devices, but also need to pay for related software licenses and maintenance.

[0004] In summary, the existing hot backup method for node hot data has the problem of low hot backup efficiency of node data, and poor reliability and availability of node hot backup work. Summary of the invention

[0026] Embodiment 1

[0027] Figure 1A flowchart of a hot backup method for node data provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where hot backup of node data is performed. The method can be executed by a hot backup device for node data. The hot backup device for node data can be implemented in the form of hardware and / or software. The hot backup device for node data can be configured in a terminal or server with a hot backup function for node data.

[0028] like Figure 1 As shown, the method includes:

[0029] S110 . In response to various data backup related operations performed by the user, various data generated by the operations are sent to various nodes in the backup cluster for common storage.

[0030] Specifically, in this embodiment, in response to various data backup-related operations performed by the user, such as manually setting the backup time interval, selecting a specific data range for backup, specifying the backup storage location, etc., the system will perform detailed analysis and processing on various types of data generated by these operations. Then, the processed data will be accurately sent to each node in the backup cluster, and the joint storage will be achieved through the collaborative work of each node. In this process, each node is responsible for storing all data through data synchronization to ensure the integrity and correctness of the data in each node.

[0031] It should be noted that, in order to ensure that the data in the hot backup node is comprehensive and correct, each node in the backup cluster is preferably set to a data synchronization mode, that is, each node stores the same order of magnitude and consistent content to be backed up data; wherein, the data synchronization is a process to ensure that the data in different locations, different systems or different devices maintain consistency and accuracy. Data synchronization involves real-time monitoring and comparison of data to identify any differences that may occur between source data and target data. When data is updated, inserted or deleted, the data synchronization mechanism can quickly capture these changes and accurately propagate the corresponding modifications to the relevant systems or devices. In today's highly interconnected digital environment, data synchronization is of irreplaceable importance for cross-departmental collaboration, multi-system integration, and ensuring data consistency and availability. Whether between business systems within an enterprise or in distributed applications across regions, data synchronization is silently playing a key role, supporting the smooth operation of various business processes. In summary, relevant personnel in this field should know that the method of data synchronization is a mature prior art, and this embodiment will not be repeated.

[0032] S120. Whenever a preset time period is reached, a master node is marked in each node in the backup cluster according to a preset election rule, and during the time period, data collected by the master node is sent to the server to perform a backup operation.

[0033] Optionally, in order to ensure the accuracy of the backup results obtained by the backup operation, in this embodiment, the execution mode of the backup operation can be set to overwrite backup, that is, the master node data backed up in the current time period will overwrite the master node data backed up in the server in the previous period. Through the above operation, the real-time and correctness of the backup data in the server can be guaranteed, while avoiding the storage pressure on the server caused by duplicate data storage.

[0034] The technical solution of the embodiment of the present invention responds to various data backup related operations performed by the user, and sends the various data generated by the operation to each node in the backup cluster for common storage. Thereafter, whenever a preset time period is reached, the master node is marked in each node in the backup cluster according to the preset election rules, and within the time period, the data collected by the master node is sent to the server to perform the backup operation, thereby improving the hot backup efficiency of the node data and enhancing the reliability and availability of the node hot backup work.

[0035] Embodiment 2

[0036] Figure 2 A flowchart of a hot backup method for node data provided in Embodiment 2 of the present invention. This embodiment is refined based on the above-mentioned embodiment. In this embodiment, a master node is determined among the nodes in the backup cluster according to a preset election rule, and within this time period, the data collected by the master node is sent to the server to perform a backup operation.

[0037] like Figure 2 As shown, the method includes:

[0038] S210 . In response to various data backup related operations performed by the user, various data generated by the operations are sent to various nodes in the backup cluster for common storage.

[0039] S220. Whenever a preset time period is reached, an online confirmation message is sent to each node in the backup cluster, and the node that successfully feeds back an election message in response to the online confirmation message is identified as the current running node.

[0040] Specifically, during the operation of the entire system, whenever a preset time period is reached, such as a specific time interval such as every hour, every day or every week, an online confirmation message will be sent to each node in the backup cluster; wherein the online confirmation message is a specific instruction or signal used to confirm whether the current node is in a normal operating state. Subsequently, the system will identify the node that successfully feeds back the election message for the online confirmation message as the current operating node. For example, when the node receives the online confirmation message, it quickly performs self-detection, including hardware status (such as CPU operation status, memory usage, etc.), software operation status (such as whether the process is normal, whether the service is available, etc.), and feeds back the detection results to the system in the form of an election message. If the node can accurately complete the feedback within the specified time, it will be identified as the current operating node and undertake the corresponding data processing and storage tasks; it should be noted that the specific content of the election message can be manually set according to actual needs, and this embodiment does not limit this. Such a mechanism can ensure that the system can always effectively identify the currently running nodes and nodes in the shutdown state within the current time period, avoiding the problem of hot backup operation failure caused by incorrectly setting the master node as a node in the shutdown state.

[0041] S230: Select a unique target node from each currently running node according to the node quantity, node number and at least one of the preset election rules of each currently running node, and mark the target node as a master node.

[0042] Among them, according to the node quantity, node number and at least one of the preset election rules of each currently running node, a unique target node is selected from each currently running node, including: if the number of currently running nodes is unique, the current running node is determined as the only target node.

[0043] Further, based on the above steps, if the number of currently running nodes is not unique and the preset election rule is an automatic election rule, determine whether there is a node marked as a master node among each currently running node; if there is a node marked as a master node, the master node is determined as the target node; if there is no node marked as a master node, the current running node with the smallest node number is selected from each currently running node and determined as the target node.

[0044] Optionally, a unique target node is selected from each currently running node based on the number of nodes, the node number and at least one of the preset election rules of each currently running node, including: if the number of currently running nodes is not unique and the preset election rule is a manual election rule, obtaining a specified node number in the preset election rule; detecting whether the current running node matching the specified node number has been marked as a master node; if so, determining the master node as the unique target node; if not, determining the current running node matching the node number as the unique target node.

[0045] On the basis of the above steps, after sending the data collected by the master node to the server to perform the backup operation, it also includes: after detecting that an election message sent by a node that is not the current running node is received within the time period, the node is identified as the current running node; returning to execute the operation of selecting a unique target node from each current running node based on the node quantity, node number and at least one of the preset election rules of each current running node.

[0046] Optionally, after sending the online confirmation information to each node in the backup cluster, it also includes: if no election message fed back by any node is received within a complete time period, generating network abnormality information to prompt relevant personnel.

[0047] In a specific implementation of this embodiment, in the operation process of the entire system, it is necessary to accurately select a unique target node from each current running node based on multiple key factors of each current running node, such as the number of nodes, the node number, and at least one of the preset election rules; wherein the number of nodes refers to the total number of nodes currently in operation, and the node number is a unique identifier assigned to each node to distinguish different nodes. Specifically, if the number of current running nodes is unique, then the current running node is directly determined as the only target node. Further, if the number of current running nodes is not unique, and the preset election rule is an automatic election rule, then it is necessary to determine whether there is a node that has been marked as a master node in each current running node. For example, the master node may be marked in advance based on the previous operation status or specific performance indicators. If there is a node that has been marked as a master node, the master node is determined as the target node; if there is no node that has been marked as a master node, then the current running node with the smallest node number is selected from each current running node and determined as the target node.

[0048] Another optional situation is that if the number of currently running nodes is not unique, and the preset election rule is a manual election rule, then the specified node number is obtained in the preset election rule. Next, it is detected whether the current running node that matches the specified node number has been marked as the master node. If so, the master node is determined as the only target node; if not, the current running node that matches the node number is determined as the only target node. After sending the data collected by the master node to the server to perform the backup operation, it also includes the following steps: after detecting that an election message sent by a non-current running node is received within the time period, the node is identified as the current running node, and then the operation of selecting a unique target node in each current running node is returned based on the number of nodes, the node number and at least one of the preset election rules of each current running node.

[0049] Optionally, after sending the online confirmation information to each node in the backup cluster, the following situation is also included: if no election message is received from any node within a complete time period, network abnormality information will be generated to prompt relevant personnel. For example, the network abnormality information can be sent to the staff responsible for network maintenance and management through pop-up windows, emails, or text messages, so that they can take timely measures to solve the problem and ensure the normal operation of the system.

[0050] The technical solution of the embodiment of the present invention responds to various data backup related operations performed by the user, and sends the various data generated by the operation to each node in the backup cluster for common storage. Thereafter, whenever a preset time period is reached, an online confirmation message is sent to each node in the backup cluster, and the node that successfully feeds back an election message for the online confirmation message is identified as the current running node. Thereafter, based on the node quantity, node number and at least one of the preset election rules of each current running node, a unique target node is selected from each current running node, and the target node is marked as the master node. Finally, the data collected by the master node is sent to the server to perform the backup operation, thereby solving the problem that the hot backup efficiency of node data is low and the reliability and availability of node hot backup work are poor due to the existing hot backup method of node hot data, thereby improving the hot backup efficiency of node data and enhancing the reliability and availability of node hot backup work.
