Description

A key business emergency guarantee method and system commonly used in the IT industry

Technical Field

The present invention relates to the field of IT technology, and more specifically, to a key business emergency guarantee method and system commonly used in the IT industry.

Background technique

Traditional information system disaster recovery is mainly divided into two methods: data disaster recovery and application high availability. There are many solutions and related products, but neither method can provide complete business continuity guarantee. Business continuity guarantee of information systems belongs to business-level disaster recovery, which needs to solve problems such as data backup and recovery, application succession, and network connection relationship invariance.

The main solution to ensure the continuity of information system business is the two-site three-center solution. The two centers in the same city with a short distance provide active-standby or active-active business support, and the remote center in a different location only provides data backup. Generally, the two-site three-center solution needs to be customized based on the specific technical architecture of the business system, and needs to be considered from multiple levels such as network environment, storage devices, virtualization, operating system, database, middleware, and application programs. The solution is complex, the construction cost is high, and each case is discussed separately. There is no universal solution.

Traditional financing has some disadvantages, such as:

Data disaster recovery is to regularly perform full and incremental backups of data, and then restore data from the backup system after a failure occurs. This method only solves data availability and consistency, but does not solve application continuity.

Application disaster recovery generally adopts HA high availability solutions, such as application clusters, load balancing, etc. These methods only solve the continuous availability of applications, and it is difficult to solve data availability and consistency.

The two-site three-center solution can achieve data availability and consistency, as well as application continuity. However, the construction cost is high, there is no universal method, and it cannot achieve business continuity guarantees in remote locations.

Summary of the invention

In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a key business emergency guarantee method and system commonly used in the IT industry, and solve the problems raised in the above-mentioned background technology through the following scheme.

To achieve the above objectives, the present invention provides the following technical solutions: a key business emergency support system commonly used in the IT industry, including a management control module, an online replication module, a memory incremental data synchronization module, a business real-time monitoring module and a business succession module.

Preferably, the management control module is used to implement the management functions of online replication task management, business assurance group configuration wizard, data synchronization policy management, business monitoring and succession management, and system resource monitoring, and other module functions can be managed and configured in the console.

Preferably, the online replication module is used to implement one-click replication of the operating system, application programs, drivers, configuration information, databases, and files without shutting down the business end and without interrupting the business, thereby forming a backup environment consistent with the main end.

Preferably, the memory incremental synchronization module is used to realize real-time synchronization of data between the active end and the standby end. The memory incremental synchronization module monitors the data changes in the IO buffer in real time, filters out business-related change data in real time, and sends it to the standby end through the network in real time. The memory incremental synchronization module runs in the operating system kernel layer, and there is no need to access the disk IO for real-time data synchronization.

Preferably, the real-time business monitoring module provides real-time detection of power outages, network disconnections, port availability, process survival, system resources, database availability, interface availability and system load conditions for the active end. It can detect system failures within seconds and notify the business succession module to perform business succession.

Preferably, the service succession module allows the backup end to promptly take over the service of the primary end when a failure occurs. The succession time is the startup time of the backup end service program and the IP address drift time, which is generally from several seconds to several minutes. It supports service succession within the same network segment and across network segments, supports automatic service switching, manual switching and service switching back, and supports disaster recovery service drills.

Preferably, a key business emergency guarantee method commonly used in the IT industry is characterized by comprising: a management control unit, an online replication unit, an incremental data synchronization unit, a business real-time monitoring unit and a business succession unit.

Preferably, the management control unit is used to notify the online replication unit to prepare to execute the replication task.

Preferably, the online replication unit is used to execute the replication task, first creating a system snapshot for the active end, and then completely copying the snapshot to the standby end. The incremental data synchronization unit captures the incremental data generated by the active end during the snapshot copy and saves it in the active end file queue. After the system snapshot copy is completed, the incremental data in the active end file queue is synchronized to the standby end to ensure data consistency at both ends. The online replication unit reports the task progress status to the management control unit in real time during the replication process.

Preferably, when the replication is completed, the online replication unit verifies the replication result through the management control unit. If the verification passes, it means that the replication is successful; if the verification fails, a second replication can be initiated in the management control unit.

Preferably, the memory incremental data synchronization unit configures the paths to be protected, including disks, directories, and files, through a management control unit.

Preferably, the real-time service monitoring unit configures the active-end service program to be monitored through the management control unit, including the service program name, start/stop commands, start/stop dependency, fault monitoring means and fault monitoring execution step.

Preferably, the service succession unit configures succession strategies of automatic succession, fault warning time and service IP switching mode through a management control unit.

Preferably, the incremental data synchronization unit can capture the incremental data of the main-side memory IO buffer in real time during the normal operation of the main-side business, filter out the path-related data of the management control unit to verify the configuration of the online replication unit, send it to the backup-side client agent program through the network bypass, and then write it sequentially into the corresponding files of the backup side.

Preferably, the real-time business monitoring unit is used to monitor various fault conditions on the main end in real time, including power outages, network disconnections, program crashes, unresponsive processes, and software and hardware failures with high system resource usage. After determining that a business failure has occurred, the real-time business monitoring unit can provide a voice warning to notify the on-duty personnel to handle it as soon as possible, and at the same time issue a business succession instruction to notify the business succession unit to prepare for succession.

Preferably, upon receiving the service succession instruction, the service succession unit immediately performs service succession by first starting the backup end service program and then performing service IP switching.

Preferably, the management control unit pushes back the full and incremental data of the standby end to the active end when the fault on the active end is repaired. The standby end continues to provide service access during the data push back process. When the data push back is completed, the service is switched back to the active end with one click to ensure uninterrupted service.

Technical effects and advantages of the present invention:

1. Based on the online replication technology of the present invention, there is no need to rely on the original software and hardware suppliers, and there is no need to build a system in a layered manner in the backup environment. The main end environment is backed up to the backup end as a whole at one time, and the backup end can operate normally. During the implementation period, the business program of the main end continues to run, and online hot standby is performed. The implementation process omits the work of building a layered environment on the backup end in the traditional disaster recovery solution, which greatly shortens the construction period. The implementation period of the traditional disaster recovery solution that takes several days can be shortened to less than 30 minutes;

2. Based on the memory incremental data capture technology of the present invention, the business data can be synchronized to the standby end in real time. The synchronization process has no IO overhead on the primary end and the CPU overhead is extremely low. The data synchronization time of this method can reach millisecond level, ensuring the real-time consistency of the data on the primary and standby ends.

3. The real-time fault monitoring module of the present invention can detect faults immediately. Once the main end system fails due to power outage, network disconnection, damage or crash, the real-time business succession module developed by the complainant can immediately transfer the business to the backup end for continuous operation without the need for human intervention. The entire succession process is automatic and imperceptible to users and IT operation and maintenance personnel.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Referring to FIG. 1 , the present invention provides a key business emergency support system commonly used in the IT industry, characterized in that it includes: a management control module, an online replication module, a memory incremental data synchronization module, a business real-time monitoring module and a business succession module.

The management control module is used to implement the management functions of online replication task management, business assurance group configuration wizard, data synchronization strategy management, business monitoring and succession management, and system resource monitoring. Other module functions can be managed and configured in the console.

The online replication module is used to achieve one-click replication of the operating system, application programs, drivers, configuration information, databases, and files without shutting down the business end and without interrupting the business, thereby forming a backup environment consistent with the main end.

The memory incremental synchronization module is used to realize real-time synchronization of data between the active end and the standby end. The memory incremental synchronization module monitors the data changes in the IO buffer in real time, filters out business-related change data in real time, and sends it to the standby end through the network in real time. The memory incremental synchronization module runs in the operating system kernel layer, and there is no need to access the disk IO for real-time data synchronization.

It is the solution with the lowest resource overhead among all data backup technologies, has wide adaptability, and can support real-time synchronization of various files and databases. It is technically independent of software and hardware manufacturers and has no dependence on the technical implementation method of the business.

The service real-time monitoring module provides real-time detection of power outages, network disconnections, port availability, process survival, system resources, database availability, interface availability and system load conditions for the active end. It can detect system failures within seconds and notify the service succession module to perform service succession.

The service succession module allows the backup end to promptly take over the service of the primary end when a failure occurs. The succession time is the startup time of the backup end service program and the IP address drift time, which is generally from several seconds to several minutes. It supports service succession within the same network segment and across network segments, supports automatic service switching, manual service switching and service switching back, and supports disaster recovery service drills.

Referring to FIG2 , the present invention provides a key business emergency guarantee method commonly used in the IT industry, characterized in that it includes: a management control unit, an online replication unit, an incremental data synchronization unit, a business real-time monitoring unit, and a business succession unit.

The management control unit is used to notify the online replication unit to prepare to execute the replication task.

The online replication unit is used to execute the replication task. It first creates a system snapshot for the active end and then completely copies the snapshot to the standby end. The incremental data synchronization unit captures the incremental data generated by the active end during the snapshot copy and saves it in the active end file queue. After the system snapshot copy is completed, the incremental data in the active end file queue is synchronized to the standby end to ensure that the data on both ends are consistent. The online replication unit reports the task progress status to the management control unit in real time during the replication process.

When the online replication unit completes the replication, the management control unit verifies the replication result. If the verification is passed, it means the replication is successful. If the verification fails, a second replication can be initiated in the management control unit.

The memory incremental data synchronization unit configures the paths to be protected, including disks, directories, and files, through the management control unit.

The service real-time monitoring unit configures the main end service program to be monitored through the management control unit, including the service program name, start and stop commands, start and stop dependency, fault monitoring means and fault monitoring execution step.

The service succession unit configures the succession strategies of automatic succession, fault warning time and service IP switching mode through the management control unit.

The incremental data synchronization unit can capture the incremental data of the main end memory IO buffer in real time during the normal operation of the main end business, filter out the path-related data of the management control unit to verify the configuration of the online replication unit, send it to the backup end client agent program through the network bypass, and then write it into the corresponding files of the backup end in sequence.

The incremental data synchronization unit does not need to access the main storage device during data synchronization, and directly captures the file IO changes in the system kernel to avoid pressure on the business system. This method is suitable for various application scenarios and has no intrusion or performance impact on the business system.

The real-time business monitoring unit is used to monitor various fault conditions on the main end in real time, including power outages, network disconnections, program crashes, unresponsive processes, and software and hardware failures with high system resource usage. After determining that a business failure has occurred, the real-time business monitoring unit can provide a voice warning to notify the on-duty personnel to handle it as soon as possible, and at the same time issue a business takeover instruction to notify the business takeover unit to prepare for takeover.

The service succession unit receives the service succession instruction and immediately performs service succession, first switches the service IP, then synchronizes the remaining incremental data, and finally starts the standby end service program.

The management control unit pushes back the full and incremental data of the standby end to the active end when the fault on the active end is repaired. During the data push back process, the standby end continues to provide service access. When the data push back is completed, the service is switched back to the active end with one click to ensure uninterrupted service.

The present invention constructs a key business emergency guarantee system that is connected in parallel with the main-end network through a backup-end bypass mounting method, integrating the full link and five elements of "backup-monitoring-early warning-succession-management". It can be applied to local or remote business guarantees of various information systems, can improve the high availability of the main system, effectively deal with various faults, and reduce the pressure of system operation and maintenance.
