The disaster recovery, namely disaster recovery, is characterized in that a systematic data emergency mode is established in advance by using scientific technical means and methods to deal with the occurrence of disasters. The content of the method comprises data backup and system backup, service continuous planning, personnel architecture, communication guarantee, crisis public relations, disaster recovery planning, disaster recovery plan, service recovery plan, emergency response, third-party cooperative organization and supply chain crisis management and the like.
The multi-level disaster recovery method provided by the invention is used for disaster recovery of the data service system, and the data service system uses third-party data in real time under the normal working condition. Referring to fig. 1, fig. 1 is a flowchart of a multi-level disaster recovery method provided in the present invention, and as shown in fig. 1, the method includes:
s1, setting a multi-stage disaster recovery operation strategy for the data service system, and enabling the data service system to allocate the current data flow in proportion to simultaneously operate a normal operation strategy and the multi-stage disaster recovery operation strategy;
wherein the current data traffic is new user data entering the data service system. The multi-stage disaster preparation operation strategy is used for dealing with different abnormal types of third-party data.
In one example, as shown in fig. 2, a first-level disaster recovery policy is set to cope with the exception type of the third-party data complete interruption (i.e., the data service system does not receive any third-party data). Taking financial wind control business as an example, in the first-level disaster recovery policy, a wind control policy without any third-party data is set, for example, a wind control policy using first-party data or second-party data is set, where the first-party data, that is, data owned by an enterprise, is data collected by the enterprise directly from audiences (including clients, website visitors, and social media concerns), may be business data generated by users in an enterprise database, and may also be behavior data of some users collected through logs. The second party data is the first party data that is not collected by the enterprise. Second party data is sometimes shared between trusted partners who, if both parties are in favor of the business, agree to share the audience's insight. For example, if a software company resells its product in collaboration with an agent partner, the software company may share its first party data with the agent, which the agent partner will use as second party data to lock and attract new customers.
In the invention, the wind control strategy without any third-party data is the same as the wind control strategy in normal operation, but the adopted data is different, so that when the third party number is interrupted, the wind control strategy without any third-party data can be directly adopted, the time for reanalyzing and fitting the risk strategy rule is saved, and the risk loss is reduced.
In another example, as shown in fig. 2, a second-level disaster recovery policy is set to cope with the abnormal type of the data quality degradation of the third party. Taking financial wind control business as an example, the data quality reduction may be reduction of the discrimination of the data to the risk or incapability of discriminating the risk. Specifically, a wind control strategy containing multi-party data can be set. For example, a wind control policy is set that includes first party data, second party data, and third party data. In this way, when the quality of the third-party data is reduced, the wind control strategy can be continuously executed according to the second-party data and the third-party data.
S2, monitoring whether the third-party data is abnormal or not;
in the invention, the third-party data abnormality refers to a situation that a data service system has business risks due to instability of third-party data. The data quality can be specifically completely interrupted by the third party data, or the data quality of the third party is reduced.
S3, if the third-party data is abnormal, judging the abnormal type of the third-party data;
the complete interruption of the third-party data can be judged by monitoring whether the data service system can receive the third-party data in real time. The quality reduction of the third-party data can be judged according to whether the discrimination degree of the third-party data on the risks in the wind control strategy or the wind control model is reduced.
And S4, switching the operation strategy of the data service system to a disaster recovery operation strategy of a corresponding level according to the abnormal type of the third-party data.
Illustratively, if the exception type is that the third-party data is completely interrupted, all data traffic of the current data service system is switched to the first-stage disaster recovery policy.
And if the abnormal type is the third-party data quality reduction, at least partially switching the data flow of the current data service system for the normal operation strategy to the second-level disaster recovery strategy so as to improve the data quality. In a specific manner, the data traffic of the current data service system for the normal operation policy is at least partially switched to the second-level disaster recovery policy according to the validity of the third-party data, where the validity of the third-party data refers to the capability of the third-party data to distinguish the user attribute, and the smaller the distinguishing degree of the third-party data to the user is, the smaller the validity of the third-party data is. Taking financial wind control business as an example, the effectiveness of the third party data can be measured according to the degree of discrimination of the third party data to the risk users in the wind control strategy or the wind control model.
Further, a first effective rate and a second effective rate may be set to perform switching of the data traffic of the normal operation policy to the second-level disaster recovery policy, where the first effective rate is smaller than the second effective rate. If the effective rate of the third-party data is greater than the first effective rate and less than the second effective rate, the effective rate of the current third-party data is lower, the current third-party data can be stopped, and new third-party data can be collected for use. And if the effective rate of the third-party data is less than the first effective rate, which indicates that the third-party data cannot meet the business requirement, at least partially switching the data traffic of the current data service system for the normal operation strategy to the second-level disaster recovery strategy.
In another specific embodiment, if the data traffic of the current data service system for the normal operation policy is at least partially switched to the second-level disaster recovery policy, the effective rate of the third-party data is monitored in real time; and adjusting the data flow switched to the second-level disaster recovery strategy in real time according to the effective rate of the third-party data so as to improve the utilization rate of the third-party data. For example, the effective rate of the third-party data is greater than the preset effective rate, and the data traffic switched to the second-level disaster recovery strategy is increased; or, when the effective rate of the third-party data is greater than the first preset efficiency and less than the second preset efficiency, adjusting the data traffic switched to the second-level disaster recovery policy to be within a first preset range, for example, within a ratio range of 40% of the whole data traffic. And when the effective rate of the third-party data is greater than a second preset efficiency, adjusting the data traffic switched to the second-level disaster recovery strategy to be within a second preset range, such as a proportion range of 40-70% of the whole data traffic, and the like.
The data service system of the invention uses the third party data in real time under the normal working condition, sets a multi-stage disaster backup operation strategy for the data service system, and enables the data service system to allocate the current data flow in proportion to simultaneously operate the normal operation strategy and the multi-stage disaster backup operation strategy; when the third-party data is monitored to be abnormal, the operation strategy of the data service system is switched to the disaster recovery operation strategy of the corresponding level according to the abnormal type of the third-party data, so that the normal operation of the data service system is ensured and the stability of the system is improved when the third-party data is abnormal.
