Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The power data disaster recovery method provided by the application can be applied to an application environment shown in figure 1. Wherein the first server 102 communicates with the second server 104 via a network. The first server 102 and the second server 104 may be configured in a distributed storage dual-activity architecture, and the second server 104 may normally receive a to-be-processed power service request sent from a user terminal and process the power service request. The first server 102 may acquire the power service request to be processed of the second server 104 when the fault information of the second server 104 is detected, process the power service to be processed using the same service logic as the second server 104 based on the stored power data of the second server 104, and store the power data to be processed in the power service request to form the stored power data. The first server 102 and the second server 104 may be implemented as separate servers or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, a power data disaster recovery method is provided, and the method is applied to the first server in fig. 1 for illustration, and includes the following steps:
Step S202, detecting fault information of a second server, and acquiring a power service request to be processed of the second server; the power service request to be processed comprises power data to be processed; the first server stores the same stored power data and business processing logic as the second server; the stored power data and the service processing logic are obtained by performing data synchronization with the first server when the second server stores the power data to be processed in the power service request sent by the user terminal.
The user terminal can be a terminal held by a user needing to perform power service, and the user can perform corresponding power service through the user terminal; the second server may be a primary server and the first server may be a backup server. The second server 104 may receive the pending power service request sent from the user terminal under normal conditions, and process, based on the stored power data in the second database of the second server 104, the pending power service request sent by the user terminal through service processing logic of the second server 104. The first server 102 and the second server 104 may be disposed in the same distributed storage dual-active architecture.
The first server 102 and the second server 104 may be communicatively connected, and may implement bidirectional synchronization of data and services, and when the second server 104 fails, for example, when a natural disaster or a human damage occurs, the second server 104 may send failure information to the first server 102, and the first server 104 may detect the failure information of the second server 104 and perform disaster recovery processing through the first server 102. When the second server 104 fails, the first server 102 may obtain the pending power service request being processed by the second server 104. Wherein, the power service request to be processed includes power data to be processed. Because the dual-center synchronization mode is adopted between the first server 102 and the second server 104, the primary server and the secondary server can process data simultaneously to realize real-time increment, and therefore the first server 102 stores the same stored power data and the same business processing logic as the second server 104. The stored power data represents power data formed by storing the obtained processed power data after the first server 102 or the second server 104 processes the power service to be processed, that is, the stored power data is power data stored in a database. The service processing logic may be processing logic for a power service request to be processed, for example, the power service to be processed may be a data writing request, and the first server 102 and the second server 104 have the same storage principle for the power service request to be processed.
When the second server 104 stores the power data to be processed, before the processing result is returned to the user terminal, data synchronization can be initiated to the first server 102, and the first server 102 and the second server 104 can synchronize the service processing logic and the stored power data, so as to ensure the data consistency and the processing logic consistency between the first server 102 and the second server 104.
Step S204, the power service request to be processed is processed according to the service processing logic, and the power data to be processed is stored in the first database of the first server as the stored power data.
The service processing logic of the first server 102 may be the same service processing logic as the second server 102, where the first server 102 is used as a standby server, when the second server 102 fails, a to-be-processed power service request that is being processed by the second server 102 may be processed according to the same service processing logic as the second server 104, where the to-be-processed power service request includes to-be-processed power data, the first server 102 processes the to-be-processed power data to obtain processed power data, and the first server 102 may store the processed power data in a first database of the first server 102 as new stored power data, thereby implementing update of the database and completing processing of the to-be-processed power service of the user terminal, implementing disaster recovery processing of the power data, so that when the second server 104 as a main server fails, power data disaster recovery processing may also be performed by the first server 102, implementing non-inductive switching, and non-inductive processing of the power service.
The above-mentioned various power data may be unstructured power data, and the above-mentioned processing of disaster recovery for power data may be a data disaster recovery method based on unstructured data, and because the unstructured data is large in volume and the individual files are stored in large amounts, the above-mentioned first server 102 and second server 104 may adopt a dual-center synchronization mode, so that disaster recovery capability is ensured, data loss is reduced, and real-time increment of power data is realized. Through the double-center synchronization mode, data between the first server 102 and the second server 104 are not different, the service system can be used after being switched, the risk of data loss is reduced, and long-term stable operation of the service system is ensured.
In the power data disaster recovery method, when the second server is detected to be faulty, the power service request to be processed, which is being processed by the second server, is acquired. The first server stores the same stored power data and service processing logic as the second server, and the stored power data and service processing logic are obtained by performing data synchronization with the first server when the second server stores the power data to be processed in the power service request. The first server processes the power service request to be processed according to the service processing logic, stores the power data to be processed into the first database as stored power data, and when the second server is detected to resume operation, the first server can perform data synchronization with the second server to resume the data of the second server. Compared with the traditional backup disaster recovery mode based on the local disk, the method and the system utilize the first server which has the same stored power data and service processing logic as the second server, and process the power service request which is being processed by the second server when the second server fails, thereby realizing the noninductive processing of the service and improving the backup efficiency of the power data disaster recovery.
In one embodiment, further comprising: receiving a multi-copy request sent by a second server; the multi-copy request comprises processed power data obtained after the second server processes the power service request sent by the user terminal; acquiring processed power data in the multi-copy request and storing the processed power data in a first database to obtain stored power data; sending storage completion information to a second server; the second server is used for receiving the storage completion information and returning the power business processing completion information to the user terminal.
In this embodiment, under normal operation conditions, the second server 104 may be used as a main server to receive a power service request of a user terminal, and after the second server 104 processes the power service request, processed power data may be obtained. The first server 102 and the second server 104 may be designed according to a distributed storage (Ceph) dual-active architecture, where Ceph is a unified distributed storage system, and the design is designed to provide better performance, reliability, and scalability. The second server 104 may send a multi-copy request to the first server 102 after storing the processed power data in the pending power service request, and the first server 102 may receive the multi-copy request sent by the second server 104 before feeding back the processing completion information to the user terminal. Among these, the presence of multiple copies is a necessary means to promote the reliability, availability, performance, and scalability of a distributed system. Replication may improve system reliability, multiple replicas may be used to split, e.g., a master-multiple-slave structure of a database, and may also be used to speed up response times, e.g., cdn, which may have utility in enhancing system availability and extensibility.
The first server 102 may receive the multiple copy request sent by the second server 104. The multi-copy request may include processed power data obtained after the second server processes the power service request sent by the user terminal. First server 102 may obtain the processed power data in the multi-copy request and store the processed power data in a first database of first server 102, resulting in stored power data stored in first server 102. Thereby enabling real-time data synchronization of the first server 102 and the second server 104. After the first server 102 synchronizes the power data that has just been processed by the second server 104, the storage completion information may be sent to the second server 104, and after the second server 104 receives the storage completion information sent by the first server 102, which represents that the real-time synchronization of the data between the first server 102 and the second server 104 has been completed, the second server 104 may return the power service processing completion information to the user terminal after receiving the storage completion information. After receiving the power service processing completion information, the user terminal can generate corresponding prompt information so that the user knows that the power service is processed. The power service processing completion information may be information in the form of a code.
For example, taking power service as power data writing as an example, when a service request writes data, the service request defaults to a main center, namely the second server 104, and after the second server 104 finishes storing, a multi-copy request can be sent to a standby center, namely the first server 102, and after the first server 102 finishes multi-copy, the second server 104 can return 200OK information to the user terminal to prompt the user terminal that the data writing is completed.
Through the embodiment, when the second server 104 completes the processing of the power service, the first server 102 can synchronize the data copied by multiple copies with the second server 104, so that the number of the main servers and the backup servers is not different, and real-time increment is realized, thereby improving the backup efficiency of disaster recovery of the power data.
In one embodiment, after processing the pending power service request according to the service processing logic and storing the pending power data to the first database of the first server as stored power data, further comprising: and receiving the recovery operation information sent by the second server, and synchronizing the stored power data in the first database with the stored power data in the second database of the second server through the object storage gateway service.
In this embodiment, when the second server 104 fails, the first server 102 may process the power service being processed by the second server 104. The first server 102 may store the power data therein after processing the power service request, to obtain the stored power data. Since the second server 104 may be malfunctioning at this time, the stored power data at the time of the first server 102 and the stored power data at the time of the second server 104 may be different. When the second server 104 resumes normal operation, the first server 102 may receive the resume operation information sent by the second server 104 and synchronize the stored power data in the first database with the stored power data in the second database in the second server 104 through the RGW (RADOS Gateway, object storage gateway) service. The synchronization between the first database and the second database may be a bidirectional synchronization based on an RGW service in a distributed storage dual-active structure, where the RGW service is a storage service supported by the Ceph overall architecture. The data synchronization process between the main server and the standby server and the service request belong to asynchronous operation, and the synchronization time cannot be ensured, so that the data synchronization between the main server and the standby server can be timely completed through an internal consistency check mechanism, and the consistency of power data is ensured.
Through the embodiment, after the second server 104 resumes normal operation, the first server 102 can perform data synchronization with the stored power data of the second server 104, thereby improving the disaster recovery backup efficiency of the power data and ensuring the data consistency between the primary server and the backup server.
In one embodiment, as shown in fig. 3, a power data disaster recovery method is provided, and the method is applied to the second server in fig. 1 for illustration, and includes the following steps:
Step S302, fault information of a second server is detected, and a power service request to be processed, which is sent by a user terminal and comprises power data to be processed, is sent to a first server; the first server is used for processing the power service request to be processed according to the same service processing logic as the second server, and storing the power data to be processed into a first database of the first server as stored power data.
The user terminal can be a terminal held by a user needing to perform power service, and the user can perform corresponding power service through the user terminal; the second server may be a primary server and the first server may be a backup server. The second server 104 may receive the pending power service request sent from the user terminal under normal conditions, and process, based on the stored power data in the second database of the second server 104, the pending power service request sent by the user terminal through service processing logic of the second server 104. The first server 102 and the second server 104 may be disposed in the same distributed storage dual-active architecture.
The first server 102 and the second server 104 may be communicatively connected, and may implement bidirectional synchronization of data and services, and when the second server 104 fails, for example, when a natural disaster or a human damage occurs, the second server 104 may send failure information to the first server 102, and the first server 104 may detect the failure information of the second server 104 and perform disaster recovery processing through the first server 102. When the second server 104 fails, the first server 102 may obtain the pending power service request being processed by the second server 104. Wherein, the power service request to be processed includes power data to be processed. Because the dual-center synchronization mode is adopted between the first server 102 and the second server 104, the primary server and the secondary server can process data simultaneously to realize real-time increment, and therefore the first server 102 stores the same stored power data and the same business processing logic as the second server 104. The stored power data represents power data formed by storing the obtained processed power data after the first server 102 or the second server 104 processes the power service to be processed, that is, the stored power data is power data stored in a database. The service processing logic may be processing logic for a power service request to be processed, for example, the power service to be processed may be a data writing request, and the first server 102 and the second server 104 have the same storage principle for the power service request to be processed.
The service processing logic of the first server 102 may be the same service processing logic as the second server 102, where the first server 102 is used as a standby server, when the second server 102 fails, the service processing logic may process a to-be-processed power service request that is being processed by the second server 102 according to the same service processing logic as the second server 104, where the to-be-processed power service request includes to-be-processed power data, the first server 102 processes the to-be-processed power data to obtain processed power data, and the first server 102 may store the processed power data in a first database of the first server 102 as new stored power data, thereby implementing update of the database and completing processing of the to-be-processed power service of the user terminal, implementing disaster tolerance processing of the power data, so that when the second server 104 as a main server fails, power data disaster tolerance processing may also be performed by the first server 102, implementing disaster tolerance switching of the power service, and non-sensing processing of the power service.
Step S304, detecting the recovery operation information of the second server, and synchronizing the stored power data in the first database with the stored power data in the second database of the second server through the object storage gateway service.
The first server 102 may process the power service being processed by the second server 104 when the second server 104 fails. The first server 102 may store the power data therein after processing the power service request, to obtain the stored power data. Since the second server 104 may be malfunctioning at this time, the stored power data at the time of the first server 102 and the stored power data at the time of the second server 104 may be different. When the second server 104 resumes normal operation, the first server 102 may receive the resume operation information sent by the second server 104 and synchronize the stored power data in the first database with the stored power data in the second database in the second server 104 through the RGW (RADOS Gateway, object storage gateway) service. The synchronization between the first database and the second database may be a bidirectional synchronization based on an RGW service in a distributed storage dual-active structure, where the RGW service is a storage service supported by the Ceph overall architecture. The data synchronization process between the main server and the standby server and the service request belong to asynchronous operation, and the synchronization time cannot be ensured, so that the data synchronization between the main server and the standby server can be timely completed through an internal consistency check mechanism, and the consistency of power data is ensured.
In the power data disaster recovery method, when the second server is detected to be faulty, the power service request to be processed, which is being processed by the second server, is acquired. The first server stores the same stored power data and service processing logic as the second server, and the stored power data and service processing logic are obtained by performing data synchronization with the first server when the second server stores the power data to be processed in the power service request. The first server processes the power service request to be processed according to the service processing logic, stores the power data to be processed into the first database as stored power data, and when the second server is detected to resume operation, the first server can perform data synchronization with the second server to resume the data of the second server. Compared with the traditional backup disaster recovery mode based on the local disk, the method and the system utilize the first server which has the same stored power data and service processing logic as the second server, and process the power service request which is being processed by the second server when the second server fails, thereby realizing the noninductive processing of the service and improving the backup efficiency of the power data disaster recovery.
In one embodiment, further comprising: receiving a power service request sent by a user terminal, and acquiring power data to be processed in the power service request; processing the power service request according to the service processing logic to obtain processed power data, and storing the processed power data to a second database of a second server as stored power data; transmitting a multi-copy request including the processed power data to a first server; the first server is used for acquiring the processed power data in the multi-copy request and storing the processed power data in the first database to obtain stored power data.
In this embodiment, under the condition of normal operation, the second server 104 may receive the power service request sent by the user terminal, and process and store the power data to be processed in the power service request, when the second server 104 stores the power data to be processed, before returning the processing result to the user terminal, data synchronization may be initiated to the first server 102, and then the first server 102 may synchronize the service processing logic and the stored power data with the second server 104, so as to ensure the data consistency and the processing logic consistency between the first server 102 and the second server 104.
Specifically, under normal operation conditions, the second server 104 may be used as a main server to receive a power service request of a user terminal, the second server 104 may receive the power service request sent by the user terminal, and obtain to-be-processed power data in the request, the second server 104 may process the power service request according to service processing logic, and obtain processed power data, and the second server 104 may store the processed power data into a second database of the second server 104 as stored power data. After the second server 104 processes the power service request, the processed power data may be obtained. The first server 102 and the second server 104 may be designed according to a distributed storage (Ceph) dual-active architecture, where Ceph is a unified distributed storage system, and the design is designed to provide better performance, reliability, and scalability. The second server 104 may send a multi-copy request to the first server 102 after storing the processed power data in the pending power service request, and the first server 102 may receive the multi-copy request sent by the second server 104 before feeding back the processing completion information to the user terminal. Among these, the presence of multiple copies is a necessary means to promote the reliability, availability, performance, and scalability of a distributed system. Replication may improve system reliability, multiple replicas may be used to split, e.g., a master-multiple-slave structure of a database, and may also be used to speed up response times, e.g., cdn, which may have utility in enhancing system availability and extensibility.
The first server 102 may receive the multiple copy request sent by the second server 104. The multi-copy request may include processed power data obtained after the second server processes the power service request sent by the user terminal. First server 102 may obtain the processed power data in the multi-copy request and store the processed power data in a first database of first server 102, resulting in stored power data stored in first server 102. Thereby enabling real-time data synchronization of the first server 102 and the second server 104. After the first server 102 stores the processed power data, corresponding processing completion information may also be returned to the second server 104 to notify the second server 104 to perform the next processing.
Through the embodiment, when the second server 104 completes the processing of the power service, the first server 102 can synchronize the data copied by multiple copies with the second server 104, so that the number of the main servers and the backup servers is not different, and real-time increment is realized, thereby improving the backup efficiency of disaster recovery of the power data.
In one embodiment, after sending the multi-copy request including the processed power data to the first server, further comprising: receiving storage completion information sent by a first server; and returning the power business processing completion information corresponding to the power business to the user terminal.
In this embodiment, after the first server 102 performs the multi-copy, corresponding storage completion information may be returned to the second server 104. The second server 104 may receive the storage completion information sent by the first server 102, and return power service processing completion information corresponding to the above power service to the user terminal. The user terminal can generate corresponding prompt information based on the service processing completion information to prompt the user that the service is processed.
Specifically, after the first server 102 synchronizes the power data that has just been processed by the second server 104, the storage completion information may be sent to the second server 104, and after the second server 104 receives the storage completion information sent by the first server 102, which represents that the real-time synchronization of the data between the first server 102 and the second server 104 has been completed, the second server 104 may return the power service processing completion information to the user terminal after receiving the storage completion information. After receiving the power service processing completion information, the user terminal can generate corresponding prompt information so that the user knows that the power service is processed. The power service processing completion information may be information in the form of a code.
For example, taking power service as power data writing as an example, when a service request writes data, the service request defaults to a main center, namely the second server 104, and after the second server 104 finishes storing, a multi-copy request can be sent to a standby center, namely the first server 102, and after the first server 102 finishes multi-copy, the second server 104 can return 200OK information to the user terminal to prompt the user terminal that the data writing is completed.
Through the embodiment, when the second server 104 completes the processing of the power service, the first server 102 can synchronize the data copied by multiple copies with the second server 104, so that the number of the main server and the backup server is not different, and real-time increment is realized, thereby improving the backup efficiency of the power data disaster recovery, and the second server 104 sends the service processing completion information to the user terminal after the first server 102 completes the copying of multiple copies, thereby ensuring that the first server 102 and the second server 104 can maintain the consistency of the data and the service logic, and improving the efficiency of the power data disaster recovery.
In one embodiment, as shown in fig. 4, fig. 4 is a flow chart of a power data disaster recovery method in yet another embodiment. As can be seen from fig. 4, the second server 104 (Cluster 1) and the first server 102 (Cluster 2) are designed in a distributed storage dual-active architecture, the first server 102 and the second server 104 can perform bidirectional synchronization of data through RGW service, and the servers and the user terminals can be connected through load balancing. Taking a service request as an example to write power data. When the service requests write data, the data is directed to the main center, namely the second server 104 by default through the load device, and after the main center stores and completes the multi-copy to the standby center (the first server 102), the second server 104 returns 200OK to the user terminal at the service side, thereby completing the data writing. Meanwhile, the data synchronization from the main center cluster to the standby center cluster can be performed, so that the disaster recovery of service data is realized, and the storage and network efficiency are optimized. When the main center fails, the load transfers the service request to the standby center, and the storage principle of the standby center is consistent with that of the data center. After the data center is restored, data synchronization can be performed between the main center and the standby center to ensure the consistency of the double-center data.
The main and standby data synchronization process and the service request belong to asynchronous operation, and the synchronization time cannot be guaranteed, so that the data synchronization between the main and standby clusters can be timely completed through an internal consistency check mechanism, and the consistency of the data is guaranteed.
By the embodiment, the first server which is the same as the stored power data and the service processing logic of the second server is utilized, and the power service request which is being processed by the second server is processed when the second server fails, so that the noninductive processing of the service is realized, and the backup efficiency of the power data disaster recovery is improved. In addition, for disaster tolerance of the unstructured power data, the operation of the service system can be recovered in a short time through the embodiment, the requirement of the service on the reliability of the information system is met, and finally, when the main center encounters natural disasters or artificial damages is realized. In addition, seamless or rapid service switching can be realized, so that service continuity is ensured. The data processing is performed between the main and the standby simultaneously due to the double-center synchronous mode, so that real-time increment is realized. And because the data is not different, the main and the standby can be switched, the service is noninductive, and the service can be used after the switching.
