Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a disaster recovery switching method, apparatus and computer equipment based on big data dual-active. Background Technology

[0002] With the development of computer technology and the widespread application of big data analysis and artificial intelligence in different fields or business systems, big data has become the data core of various business systems, undertaking the foundational function of each business system. Therefore, the requirements for business continuity and business data security performance of various business systems are increasing day by day.

[0003] Traditionally, when a business system's data center experiences a failure or is damaged, it is necessary to promptly save or restore business data to ensure business continuity. This typically involves using underlying replication technology based on off-site storage devices. Storage vendors provide dedicated underlying technology and software to mirror data between the primary central storage device and the off-site backup storage device, replicating data synchronously or asynchronously to the remote location for data preservation and subsequent recovery.

[0004] However, traditional underlying replication technologies based on off-site storage devices only have simple data replication capabilities. When a primary and backup center switch is required, the data differences between the two centers prevent business data from being directly interconnected. In other words, business data cannot be directly used between the primary and backup centers, and further data loss issues must be addressed before the system can be put back into operation. Therefore, traditional data disaster recovery switchover methods still suffer from the problem of data inconsistency preventing direct use of business data, and the business continuity of current business systems under data failures still needs improvement.

It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

When it is determined that the data processing service state is normal, the current running mode of the business system is obtained, and it is further judged whether the current running mode is the backup mode. When it is determined that the current running mode is the backup mode, the master data center is controlled to be closed, the business access interface is switched to the backup data center according to the domain name data, and the backup data center is controlled to be started. Wherein, the terminal 102 can be but not limited to various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices, the Internet of Things devices can be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The server 104 can be realized by an independent server or a server cluster composed of multiple servers.

[0061] In one embodiment, as shown in Figure 2As shown, a big data-based dual-active disaster recovery switching processing method is provided, which is applied to Figure 1 a server in , including the following steps:

[0062] In step S202, the data processing service state of the master data center and the backup data center of the business system is obtained.

[0063] Specifically, the current running state data and application configuration data of the master data center and the backup data center of the business system are obtained, and the data processing service state of the master data center and the backup data center of the business system is determined according to the current running state data and the application configuration data.

[0064] Further, the current running state data includes component state data, upstream and downstream dependency state data, and component difference data of the master data center and the backup data center, and the application configuration data includes user permission configuration data and business system application configuration data of the master data center and the backup data center. Specifically, the data processing service state of the master data center and the backup data center of the business system is determined according to the component state data, the upstream and downstream dependency state data, the component difference data, the user permission configuration data, and the business system application configuration data of the master data center and the backup data center.

[0065] Among them, the data processing service state is used to determine whether the business system is currently in a master-backup dual-active state. Specifically, when the data processing service state is normal, it can be determined that the business system is in a master-backup dual-active state, and based on the master-backup dual-center disaster recovery deployment method, the master data center and the backup data center simultaneously perform data incremental storage, the storage data volume of the master data center and the backup data center is basically consistent, and the state belongs to master-backup dual-active.

[0066] Similarly, when the data processing service state is abnormal, the master data center and the backup data center of the business system do not currently meet the master-backup dual-active state, and after further repair processing of the abnormal data, the data processing service state of the master data center and the backup data center of the business system is reacquired, and it is rejudged whether the data processing service state is normal.

[0067] In step S204, when it is determined that the data processing service state is normal, the current running mode of the business system is obtained.

[0068] Specifically, when it is determined that the data processing service state is normal, the master data center and the backup data center of the business system are in a master-backup dual-active state, and on the basis of meeting the master-backup dual-active state, the current running mode of the business system is further obtained.

[0069] The current operation mode of the business system includes a normal mode and a disaster recovery mode. In the normal mode, the business system performs data incremental storage to the primary data center and the backup data center simultaneously, but when the domain name data of the domain name system is configured, the business access interface needs to be connected with the primary data center to realize the business data read-write processing between the application system and the primary data center.

[0070] Similarly, in the disaster recovery mode, the business system performs data incremental storage to the primary data center and the backup data center simultaneously, but when the domain name data of the domain name system is configured, the business access interface needs to be connected with the backup data center to realize the business data read-write processing between the application system and the backup data center.

[0071] Step S206, when it is determined that the current operation mode is the disaster recovery mode, the primary data center is controlled to be closed, the business access interface is switched to the backup data center according to the domain name data, and the backup data center is controlled to be started.

[0072] Specifically, when it is determined that the current operation mode is the disaster recovery mode, the primary data center is controlled to be closed, the business access data is configured according to the domain name data, then the business connection between the primary data center and the application system is cut off according to the business access data, the business access interface is switched to the backup data center, and the backup data center is controlled to be started.

[0073] Further, when it is determined that the current operation mode is the disaster recovery mode, it indicates that the current primary data center has a failure or needs to be maintained, and the business connection between the primary data center and the application system needs to be cut off, so that the business data read-write processing between the application system and the primary data center cannot be performed. The business access interface is switched to the backup data center by the business access data configured by the domain name data, and the backup data center is controlled to be started, so as to realize the second-level switching between the primary data center and the backup data center, effectively prevent the data loss risk, minimize the business system downtime risk, and ensure the stable and safe operation of the business.

[0074] In the disaster recovery switching processing method based on big data dual-active, the data processing service states of the master data center and the backup data center of the business system are acquired, and the current running mode of the business system is acquired when it is determined that the data processing service states are normal. Then, the master data center is controlled to be closed, the business access interface is switched to the backup data center according to the domain name data, and the backup data center is controlled to be started when it is determined that the current running mode is the backup mode. The data processing service states of the master data center and the backup data center of the business system are normal as the basis for starting the backup mode, that is, the dual-active of the master data center and the backup data center of the business system is achieved. Since there is no difference between the data of the master data center and the backup data center, the business system can be switched for use, the risk of data loss can be effectively prevented, the risk of business system downtime can be minimized, the stable and safe operation of the business system can be ensured, and the business continuity of the business system under data failure can be improved.

[0075] In one embodiment, as shown in Figure 3 a disaster recovery switching processing method based on big data dual-active is provided, which comprises the following steps:

[0076] In step S302, the data processing service states of the master data center and the backup data center of the business system are acquired.

[0077] Specifically, the current running state data and application configuration data of the master data center and the backup data center of the business system are acquired, and the data processing service states of the master data center and the backup data center of the business system are determined according to the current running state data and the application configuration data.

[0078] The data processing service state is used to determine whether the business system is currently in a master-backup dual-active state. Specifically, when the data processing service state is normal, it can be determined that the business system is in a master-backup dual-active state. Based on the master-backup dual-center disaster recovery deployment mode, the master data center and the backup data center simultaneously perform data incremental storage, the storage data volume of the master data center and the backup data center is basically consistent, and the state belongs to the master-backup dual-active state.

[0079] Similarly, when the data processing service state is abnormal, the master data center and the backup data center of the business system do not currently meet the master-backup dual-active state, and the abnormal data needs to be further repaired. Then, the data processing service states of the master data center and the backup data center of the business system are re-acquired, and it is re-determined whether the data processing service state is normal.

[0080] In step S304, the current running mode of the business system is acquired when it is determined that the data processing service state is normal.

[0081] Specifically, when determining that the data processing service state is a normal state, the master data center and the standby data center of the business system are in a master-standby dual-active state, and on the basis of meeting the master-standby dual-active state, the current running mode of the business system is further acquired.

[0082] Step S306, when determining that the current running mode is a normal mode, the standby data center is controlled to be closed, and the business access interface is connected with the master data center according to the domain name data, the business access interface is used to provide a read-write channel for the application system to read and write the business data of the business system.

[0083] The current running mode of the business system includes a normal mode and a disaster recovery mode, in the normal mode, the business system performs data incremental warehousing to the master data center and the standby data center at the same time, but when the domain name data of the domain name system is configured, the business access interface needs to be connected with the master data center to realize the read-write processing of the business data between the application system and the master data center.

[0084] Similarly, in the disaster recovery mode, the business system performs data incremental warehousing to the master data center and the standby data center at the same time, but when the domain name data of the domain name system is configured, the business access interface needs to be connected with the standby data center to realize the read-write processing of the business data between the application system and the standby data center.

[0085] Specifically, when determining that the current running mode is a normal mode, the standby data center is controlled to be closed, the business access data is configured according to the domain name data, and then the business access interface is connected with the master data center according to the business access data. The business access interface is used to provide a read-write channel for the application system to read and write the business data of the business system, when the business access interface is connected with the master data center, the application system reads and writes the business data in the master data center through the business access interface, and conversely, when the business access interface is connected with the standby data center, the application system reads and writes the business data in the standby data center through the business access interface.

[0086] Step S308, when determining that the current running mode is a disaster recovery mode, the master data center is controlled to be closed, the business access interface is switched to the standby data center according to the domain name data, and the standby data center is controlled to be started.

[0087] Specifically, when determining that the current running mode is a disaster recovery mode, the master data center is controlled to be closed, the business access data is configured according to the domain name data, then the business connection between the master data center and the application system is cut off according to the business access data, the business access interface is switched to the standby data center, and the standby data center is controlled to be started.

[0088] Further, when it is determined that the current running mode is the disaster backup mode, it indicates that the current main data center has a failure or needs maintenance processing, and the business connection between the main data center and the application system cannot be executed to perform the business data read-write processing between the application system and the main data center. The business access interface is switched to the backup data center according to the domain name data, and the backup data center is controlled to start.

[0089] In the above-mentioned disaster recovery switching processing method based on big data dual-active, the data processing service state of the main data center and the backup data center of the business system is obtained, and when it is determined that the data processing service state is the normal state, the current running mode of the business system is obtained. When it is determined that the current running mode is the normal mode, the backup data center is controlled to be closed, and the business access interface is connected to the main data center according to the domain name data. When it is determined that the current running mode is the disaster backup mode, the main data center is controlled to be closed, and the business access interface is switched to the backup data center according to the domain name data, and the backup data center is controlled to start. The second-level switching between the main data center and the backup data center is realized, the risk of data loss is effectively prevented, the risk of business system downtime is minimized, and the stable and safe operation of the business is ensured.

[0090] In one embodiment, as shown in Figure 4 a disaster recovery switching processing method based on big data dual-active is provided, which specifically includes:

[0091] In step S402, the data processing service state of the main data center and the backup data center of the business system is obtained.

[0092] Specifically, the current running state data and the application configuration data of the main data center and the backup data center of the business system are obtained, and the data processing service state of the main data center and the backup data center of the business system is determined according to the current running state data and the application configuration data.

[0093] In step S404, when it is determined that the data processing service state is the abnormal state, an abnormality repair instruction is triggered.

[0094] Specifically, the data processing service state includes a normal state and an abnormal state, wherein when the data processing service state is the abnormal state, the main data center and the backup data center of the business system do not currently satisfy the dual-active state, and further repair processing of the abnormal data is needed, and then the data processing service state of the main data center and the backup data center of the business system is obtained again, and it is determined whether the data processing service state is the normal state.

[0095] Further, when it is determined that the data processing service state is the abnormal state, an abnormality repair instruction is triggered, which is used to realize further repair processing of the abnormal data until the data processing service state obtained after the repair is the normal state.

[0096] Step S406, in response to the exception repair instruction, determine the exception data position corresponding to the exception state.

[0097] Specifically, by responding to the triggered exception repair instruction, and obtaining the specific position of the exception data corresponding to the exception state. Wherein, the exception data type of the exception state can include component state exception data, upstream and downstream dependency state exception data and component difference exception data of the master data center and the backup data center, and can also include user permission configuration exception data and business system application configuration exception data of the master data center and the backup data center.

[0098] Further, after determining the exception data type of the exception state, the specific position of the exception data of different exception data types can be further determined.

[0099] Step S408, based on the exception data position, perform exception repair until the data processing service state is normal.

[0100] Specifically, based on the exception data position, perform exception repair, such as component state exception data, upstream and downstream dependency state exception data, component difference exception data, user permission configuration exception data and business system application configuration exception data of the master data center and the backup data center, etc., to achieve the effect of normal data processing service state.

[0101] Further, first, it can be determined whether the master data center or the backup data center has exception data, after determining the data center where the exception data appears, the exception data type is further determined. For example, when it is determined that the master data center has exception data, and the exception data type is determined to be component state exception data, the state of different components of the master data center needs to be further analyzed to determine the specific component that appears fault, and the fault handling scheme corresponding to the fault component is matched out to execute the corresponding fault handling scheme to complete the exception repair.

[0102] Wherein, for other exception data types of the master data center, it is also necessary to determine the specific fault position, further match the fault handling scheme, until the repair is completed. Similarly, for each exception data type of the backup data center, a similar exception repair processing flow can also be used until the repair is completed.

[0103] Step S410, when it is determined that the data processing service state is normal, obtain the current running mode of the business system.

[0104] Specifically, when it is determined that the data processing service state is normal, the master data center and the backup data center of the business system are in the master-backup dual-active state, and on the basis of meeting the master-backup dual-active state, the current running mode of the business system is further obtained.

[0105] Step S412, when determining that the current running mode is the normal mode, controlling the standby data center to be closed, and connecting the service access interface with the main data center according to the domain name data; the service access interface is used to provide a read-write channel for the application system to read and write the service data of the service system.

[0106] The current running mode of the service system includes a normal mode and a standby mode, in the normal mode, the service system performs data incremental storage to the main data center and the standby data center simultaneously, but when the domain name data of the domain name system is configured, the service access interface needs to be connected with the main data center to realize the read-write processing of the service data between the application system and the main data center.

[0107] Specifically, when determining that the current running mode is the normal mode, the standby data center is controlled to be closed, the service access data is configured according to the domain name data, and then the service access interface is connected with the main data center according to the service access data. The service access interface is used to provide a read-write channel for the application system to read and write the service data of the service system, when the service access interface is connected with the main data center, the application system reads and writes the service data in the main data center through the service access interface, on the contrary, when the service access interface is connected with the standby data center, the application system reads and writes the service data in the standby data center through the service access interface.

[0108] Step S414, when determining that the current running mode is the standby mode, controlling the main data center to be closed, and switching the service access interface to the standby data center according to the domain name data, and controlling the standby data center to be started.

[0109] The current running mode of the service system includes a normal mode and a standby mode, in the normal mode, the service system performs data incremental storage to the main data center and the standby data center simultaneously, but when the domain name data of the domain name system is configured, the service access interface needs to be connected with the main data center to realize the read-write processing of the service data between the application system and the main data center.

[0110] When determining that the current running mode is the standby mode, the main data center is controlled to be closed, the service access data is configured according to the domain name data, then the service connection between the main data center and the application system is cut off, the service access interface is switched to the standby data center, and the standby data center is controlled to be started.

[0111] Further, when it is determined that the current running mode is the disaster backup mode, it indicates that the current main data center has a failure or needs maintenance processing, and the business connection between the main data center and the application system cannot be executed to perform the business data read-write processing between the application system and the main data center. The business access interface is switched to the backup data center through the domain name data configuration, and the backup data center is started to realize the second-level switching between the main data center and the backup data center, effectively prevent the data loss risk, minimize the business system downtime risk, and ensure the stable and safe operation of the business.

[0112] In the above-mentioned disaster recovery switching processing method based on big data dual-active, the data processing service state of the main data center and the backup data center of the business system is obtained, when it is determined that the data processing service state is an abnormal state, an abnormal repair instruction is triggered, and the abnormal repair instruction is responded to determine the abnormal data position corresponding to the abnormal state. Further, the abnormal data position is repaired until the data processing service state is normal, and when it is determined that the data processing service state is normal, the current running mode of the business system is obtained. When it is determined that the current running mode is the normal mode, the backup data center is controlled to be closed, and the business access interface is connected with the main data center according to the domain name data. When it is determined that the current running mode is the disaster backup mode, the main data center is controlled to be closed, and the business access interface is switched to the backup data center according to the domain name data, and the backup data center is started. The data processing service state of the main data center and the backup data center of the business system is normal as the basis for starting the disaster backup mode, that is, the dual-active of the main data center and the backup data center of the business system is achieved. Since there is no difference between the data of the main data center and the backup data center, the business system switching can be used, which can effectively prevent the data loss risk, minimize the business system downtime risk, and ensure the stable and safe operation of the business system to improve the business continuity of the business system under data failure.

[0124] Step S511, according to the business access data, cutting off the business connection between the main data center and the application system, switching the business access interface to the standby data center, and controlling the standby data center to be started.

[0125] In the above-mentioned disaster recovery switching processing method based on big data dual-active, the data processing service states of the main data center and the standby data center of the business system are obtained, and when it is determined that the data processing service state is a normal state, the current running mode of the business system is obtained. Further, when it is determined that the current running mode is a disaster recovery mode, the main data center is controlled to be closed, and the business access interface is switched to the standby data center according to the domain name data, and the standby data center is controlled to be started. The data processing service states of the main data center and the standby data center of the business system are used as the basis for starting the disaster recovery mode, that is, the dual-active of the main data center and the standby data center of the business system is achieved. Since there is no difference between the data of the main data center and the standby data center, the business system can be switched for use, which can effectively prevent data loss risk, minimize business system downtime risk, and ensure stable and safe operation of the business system, thereby improving business continuity of the business system under data failure.

[0144] In one embodiment, the switching module is further configured to:

[0145] When it is determined that the current running mode is the disaster backup mode, the main data center is controlled to shut down, the business access data is configured according to the domain name data, the business connection between the main data center and the application system is cut off according to the business access data, the business access interface is switched to the backup data center, and the backup data center is controlled to start.

[0146] The modules in the disaster recovery switching processing device based on the big data dual-active mode can be all or part of software, hardware, and combinations thereof. The modules can be embedded in or independent of the processor in the computer device in the form of hardware, or can be stored in the memory in the computer device in the form of software, so as to be called and executed by the processor to perform the operations corresponding to the modules.

[0147] In one embodiment, as shown in Figure 8 , a disaster recovery switching processing system based on big data dual-active mode is provided, and as shown in Figure 8 , the disaster recovery switching processing system based on big data dual-active mode belongs to the dual-active architecture, and specifically includes a business system 802, a main data center 804, a backup data center 806, a DNS (domain name system) 808, and an application system 810.

[0148] The business system 802 simultaneously performs data incremental warehousing on the master data center 804 and the backup data center 806, that is, synchronously writes the business data into the master data center 804 and the backup data center 806, and the warehousing data amount of the master data center 804 and the backup data center 806 is basically consistent, and the state belongs to master-backup dual-live.

[0149] The application system 810 performs routing configuration through the DNS (Domain Name System) 808, obtains business access data through the configuration, and determines the accessible data center according to the business access data.

[0150] The current running mode of the business system includes a normal mode and a disaster recovery mode. In the normal mode, after the application system 810 performs routing configuration through the DNS (Domain Name System) 808, it is determined that only the master data center 804 can be accessed, and at this time, the backup data center 806 does not perform business data read-write for the application system 810, and only after disaster recovery switching, the backup data center 806 is allowed to be accessed by the application system 810 for business data read-write.

[0151] Similarly, in the disaster recovery mode, after the application system 810 performs routing configuration through the DNS (Domain Name System) 808, it is determined that only the backup data center 806 can be accessed, and at this time, the master data center 804 does not perform business data read-write for the application system 810.

[0152] Further, as shown in FIG. (a) of Figure 8 , before disaster recovery switching, that is, when the current business system 802 is in the normal mode, the business system 802 simultaneously performs data incremental warehousing on the master data center 804 and the backup data center 806, and the warehousing data amount of the master data center 804 and the backup data center 806 is basically consistent, and the state belongs to master-backup dual-live. After the application system 810 performs routing configuration through the DNS (Domain Name System) 808, it is determined that only the master data center 804 can be accessed, and at this time, the backup data center 806 does not perform business data read-write for the application system 810, and only after disaster recovery switching, the backup data center 806 is allowed to be accessed by the application system 810 for business data read-write.

[0153] Similarly, as shown in FIG. (b) of Figure 8 , after disaster recovery switching, that is, when the current business system 802 is in the disaster recovery mode, the business system 802 still simultaneously performs data incremental warehousing on the master data center 804 and the backup data center 806, and the warehousing data amount of the master data center 804 and the backup data center 806 is basically consistent, and the state belongs to master-backup dual-live. After the application system 810 performs routing configuration through the DNS (Domain Name System) 808, it is determined that only the backup data center 806 can be accessed, and at this time, the master data center 804 does not perform business data read-write for the application system 810.

[0154] The disaster recovery switching processing system based on big data double-live realizes that the data processing service state of the main data center and the backup data center of the business system is normal as the basis for starting the backup mode, that is, the double-live of the main data center and the backup data center of the business system is achieved. Since there is no difference between the data of the main data center and the backup data center, the business system switching can be used, the risk of data loss can be effectively prevented, the risk of business system downtime is minimized, the stable and safe operation of the business system is ensured, and the business continuity of the business system under data failure is improved.
