[0029] Embodiment 1

[0030] Figure 1A flowchart of a data backup method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of performing off-site data backup of system data or database data. The method can be executed by a data backup device, which can be implemented in the form of hardware and / or software. Typically, the data backup device can be configured in an electronic device, such as a computer device or a server. Figure 1 As shown, the method includes:

[0031] S110. When a data backup request sent by a scheduling server is detected, a backup rule management task is established, and a data backup subprocess is established through the backup rule management task.

[0032] In this embodiment, the data backup system may be composed of a scheduling server, a standby server, and a source platform. The scheduling server is used to call the standby server to perform system resource information statistics, process information backup and backup recovery on the source platform when disaster recovery is required, and monitor the operation of the standby server. Typically, the user can configure the backup rule information on the scheduling server, and send the backup rule information to the standby server through the scheduling server, so that the standby server can perform data backup on the source platform based on the backup rule information.

[0033] Specifically, when the backup server receives the data backup request sent by the scheduling server, it determines that it is necessary to start off-site disaster recovery, and at this time, a backup rule management task can be established. After the backup rule management task is established, a data backup subprocess can be automatically established, and the data backup subprocess is independently responsible for data transmission between the source platform. Among them, the backup rule management task can be regarded as the parent process of the data backup subprocess, and the data backup subprocess will only stop running when it receives the shutdown command sent by the backup rule management task.

[0034] S120. Establishing a communication link with the target source platform through the data backup subprocess according to the data backup request.

[0035] Specifically, the data backup subprocess can determine the target source platform and the corresponding access address that need to perform data backup, as well as the corresponding backup rule information, based on the data backup request. For example, the backup rule identifier can be obtained according to the data backup request, and based on the backup rule identifier, the matching backup rule information can be found from the preset backup rule set. Then, the data backup subprocess can establish a communication link between the backup server and the target source platform based on the above-determined information. This embodiment does not specifically limit the communication protocol based on the communication link. Among them, the source platform can be a virtual machine platform such as VMware.

[0036] Optionally, establishing a communication link with the target source platform through the data backup subprocess according to the data backup request may include:

[0037] The data backup request is subjected to content parsing to obtain backup rule information, and a communication link with a target source platform is established through the data backup subprocess according to the backup rule information.

[0038] Specifically, after establishing the backup rule management task, the standby server can parse the data backup request through the backup rule management task to obtain the backup rule information. For example, the backup rule information may include the access address of the source platform, the type of data to be backed up, the backup data storage path, the execution cycle, etc. Then, the data backup subprocess can connect to the target source platform based on the backup rule information, transfer the data to be backed up, and write the data to be backed up to the standby server.

[0039] Optionally, after parsing the content of the data backup request to obtain backup rule information, the following may also be included:

[0040] Storing the backup rule information in a lightweight data exchange format file in a preset path;

[0041] Establishing a communication link with a target source platform through the data backup subprocess according to the backup rule information may include:

[0042] The backup rule information is read from the lightweight data exchange format file of the preset path through the data backup subprocess, and a communication link with the target source platform is established according to the backup rule information.

[0043] In a specific example, after parsing the backup rule information, the standby server can store it in a lightweight data exchange format file of a specified path, typically a Json file. After establishing a data backup subprocess, the data backup subprocess can read the backup rule information from the Json file and connect to the target source platform based on the backup rule information.

[0044] In this embodiment, by setting a separate subprocess to be responsible for the transmission and writing of backup data, the security and stability of data backup can be improved.

[0045] S130: Back up data of the target source platform based on the communication link.

[0046] Specifically, the data backup subprocess may receive the data to be backed up from the target source platform based on the established communication link, and perform backup processing on the data to be backed up, for example, the data may be stored in a designated database.

[0047] Optionally, backing up data on the target source platform based on the communication link may include:

[0048] The data to be backed up of the target source platform is acquired based on the communication link through the data backup subprocess, and the data to be backed up is written to the local disk.

[0049] The data to be backed up may include system operation data, process data, database data, etc. of the target source platform. Specifically, when the standby server backs up the data of the target source platform, it may write the data to be backed up of the target source platform to the local disk through the data backup subprocess.

[0050] In a specific implementation of this embodiment, the structure of the data backup system can be as follows: Figure 2 As shown, the VMware source platform is composed of multiple virtual machines. The scheduling server obtains the platform and virtual machine information from the VMware source platform, and sends the platform and virtual machine information and backup rule information to the standby server. After that, after receiving the information sent by the scheduling server, the data backup service in the standby server can create a backup rule management task, and the task can create a data backup subprocess, for example, a vmagent process. The scheduling server can send a request to the backup rule management task to view the relevant information of the data backup.

[0051] Furthermore, the data backup subprocess can connect to the VMware source platform based on the platform and virtual machine information and the backup rule information, and write the received data to be backed up to the local disk to implement data backup. Secondly, the data backup subprocess can periodically send the backup rule information or information path to the data backup service through the interface for receiving subprocess information pre-set in the data backup service. Among them, the data backup service is pre-deployed in the backup server and can be an application for implementing data backup.

[0052] The technical solution of the embodiment of the present invention is to establish a backup rule management task when a data backup request sent by a scheduling server is detected, and to establish a data backup sub-process through the backup rule management task; to establish a communication link with the target source platform according to the data backup request through the data backup sub-process; to perform data backup on the target source platform based on the communication link, and to establish a data backup sub-process through the backup rule management task to be responsible for the data backup of the corresponding source platform, so as to ensure continuous data backup of the source platform when the service crashes or restarts, avoid accidental interruption of data backup, and improve the stability of data backup.

[0053] Optionally, the technical solution of this embodiment may further include: in the process of data backup, regularly sending the backup rule information to the backup rule management task through the data backup subprocess;

[0054] When the data backup service is restarted, if the preset timeout period has not been reached, the data backup subprocess continues to back up the target source platform, and after the data backup service is successfully restarted, it is determined whether there is a backup rule management task that matches the data backup subprocess;

[0055] If not, rebuild the backup rule management task according to the backup rule information, and continue to monitor the data backup sub-process through the backup rule management task.

[0056] In this embodiment, during the data backup process, if the data backup service crashes or restarts, the backup rule management task will be lost, the scheduling server cannot view the data backup status, and the backup rule information, process related information (such as process identifier, etc.) and task related information sent by the data backup subprocess on a regular basis cannot be received. It should be noted that the restart of the data backup service and the loss of the backup rule management task will not affect the operation of the data backup subprocess.

[0057] Therefore, within the preset timeout period, the data backup subprocess will continue to back up data on the target source platform because it has not received the shutdown instruction of the backup rule management task. If the data backup service is successfully restarted within the preset timeout period, after receiving the backup rule information sent by the data backup subprocess, the backup rule management task corresponding to the data backup subprocess cannot be found, and the backup rule management task can be rebuilt according to the backup rule information. The rebuilt backup rule management task can continue to monitor the data backup subprocess according to the process identifier sent by the data backup subprocess until the backup or recovery is completed.

[0058] The advantage of the above settings is that the data backup subprocess does not stop the transmission of virtual machine data and writing to the local disk. Data backup will not be affected by the crash or restart of the data backup service, and the entire backup process is very stable.

[0059] Optionally, the technical solution of this embodiment may also include: when the data backup service is restarted, if the data backup service has not been successfully restarted after a preset timeout period is reached, terminating the data backup of the target source platform through the data backup sub-process.

[0060] In another case, if the data backup service still fails to restart successfully after reaching the preset timeout period, it means that there may be a fault that cannot be repaired, and the data backup subprocess can choose to automatically terminate the data backup of the target source platform. The preset timeout period can be set according to historical experience.

[0061] In a specific implementation of this embodiment, the process of restarting the data backup service can be as follows: Figure 3 As shown. When the data backup service is restarted, the backup rule management task is lost, and the data backup subprocess continues to receive the data to be backed up sent by the target source platform and writes it to the local disk. After the data backup service is restarted, if the data backup service receives the backup rule information and task-related information sent regularly by the data backup subprocess, it determines whether there is a backup rule management task corresponding to the task-related information. If it is determined that it does not exist, the backup rule management task can be rebuilt according to the task-related information, and the backup rule management task continues to monitor the operation of the data backup subprocess. The scheduling server can continuously monitor whether the data backup service has been successfully restarted within a certain period of time.

[0062] The technical solution of this embodiment uses independent sub-processes to perform backup and recovery transmission, thus avoiding the direct failure of backup rules caused by the crash or restart of the data backup service, and realizing information exchange through inter-process communication, which can realize real-time monitoring of sub-processes, so that sub-processes can feedback information such as transmission progress. Secondly, by re-starting the data backup service according to the information of the sub-process, the backup rule management task is rebuilt so that the backup process will not be interrupted. Even if the service crashes or restarts when 90% of the progress is backed up, the backup can continue normally, ensuring the stability and security of the backup software and making it more competitive. Moreover, it can support the situation where the service crashes and restarts when multiple backup rules are running at the same time. Multiple sub-processes send information to the server and all are rebuilt successfully, and the transmission of any backup rule will not be stopped. In addition to the backup and recovery rules, it can also play a role in the migration, replication and drills of virtual machines to ensure the stable operation of the rules.
