Detailed Description
Embodiments of the present invention will be described below with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Those skilled in the art will appreciate that the solutions provided by the embodiments of the present invention are also applicable to similar technical problems.
The embodiment of the invention provides a disaster recovery processing method, which can reduce the occupation of storage resources in a backup data index mode, thereby improving the utilization rate of the storage resources. The embodiment of the invention also provides corresponding equipment and a corresponding system. The following are detailed below.
The current disaster recovery system comprises a main end and a standby end, wherein one copy of data stored in the main end needs to be backed up by the standby end, and thus, two copies of data need to be stored by one copy of data, which results in low utilization rate of storage resources. In order to improve the utilization rate of storage resources in a disaster recovery system and ensure the safety and stability of the disaster recovery system, embodiments of the present invention provide a light disaster recovery system, which only needs to store one copy of data and backup a data index of the stored data, thereby reducing the occupation of the storage resources and improving the utilization rate of the storage resources.
Fig. 1 is a schematic diagram of an embodiment of a disaster recovery system according to an embodiment of the present invention.
As shown in fig. 1, the disaster recovery system provided in the embodiment of the present invention includes a main service device 20A, a standby service device 20B, a main storage device 30A, and a standby storage device 30B, where the main service device 20A may receive a service request sent by a service server 10. The business server 10, the main service device 20A, the standby service device 20B, the main storage device 30A and the standby storage device 30B are connected through network communication.
The service server 10 may communicate with the user equipment and transmit a service request to the main service device 20A according to a request of the user equipment.
The main service device 20A receives a service request, which may be a service data upload request.
The main service device 20A uploads the service data to the main storage device 30A, and if the main service device 20A determines that the service data upload fails and determines that the upload failure rate in the current detection period reaches any one level of the multi-level disaster tolerance threshold, sends a remote request to the standby service device according to the disaster tolerance level corresponding to the upload failure rate.
In the embodiment of the present invention, a multi-level disaster recovery policy is set, and different levels of disaster recovery policies are configured for different failure conditions in the main service device 20A. For example: taking the upload failure rate as an example, if the upload failure rate is set to 0 level within 1%, a local retry strategy is adopted, the upload failure rate is 1 level from 1% to 20%, a remote retry strategy is adopted, the upload failure rate exceeds 20%, the remote disaster recovery strategy is adopted, and a strategy of switching all requests to remote places is adopted. Of course, this is merely an example of the multi-level disaster tolerance, and actually, both the configuration and the threshold value of the multi-level disaster tolerance policy may be set and adjusted according to the requirement.
The remote request in the embodiment of the invention refers to a request crossing a machine room, and the machine rooms are usually not arranged in the same city, so the remote request is called as a remote request.
The standby service device 20B uploads the service data to the standby storage device 30B according to the remote request.
The standby service apparatus 20B transmits the index information of the service data to the main service apparatus 20A.
The service request may be a picture upload request, for example: taking the application scene of the QQ photo album as an example, a certain QQ user uploads a picture to the QQ photo album.
After receiving the picture upload request, the main service device 20A uploads a picture to the main storage device 30A, if the picture upload is successful, only the index information of the picture needs to be synchronized to the standby service device, if the picture upload is failed, the main service device 20A needs to determine an upload failure rate in the current detection period, if the upload failure rate reaches a retry level in a different place, the main service device 20A sends a retry request in a different place to the standby service device 20B, and the standby service device 20B uploads the picture to the standby storage device 30B according to the retry request in the different place and asynchronously sends the index information of the picture to the main service device 20A for storage. If main service device 20A determines that the transmission failure rate reaches the different-location switching level, main service device 20A sends a different-location switching request to standby service device 20B, and standby service device 20B uploads the picture to standby storage device 30B according to the different-location switching request, and takes over the work of main service device 20A, processes the service request that is sent to main service device 20A later. Standby service apparatus 20B asynchronously sends the index information of the picture uploaded to standby storage apparatus 30B for main service apparatus 20A to main service apparatus 20A for storage.
When the standby service device 20B uploads the service data to the standby storage device according to the remote request, a backup mark may be further set for the service data, where the backup mark indicates that the service data is not synchronized to the main service device.
The standby service device 20B periodically synchronizes the index information of the service data indicated by the backup mark to the main service device; and the backup mark of the synchronized index information is cleared.
In order to improve the resource utilization of the storage resource of the standby storage device 30B, the standby service device 20B clears the expired data in the standby storage device 30B according to a Least Recently Used (LRU) algorithm.
In this embodiment of the present invention, the standby service device 20B may also periodically query a first index record and a second index record, where the first index record records index information recorded in the main service device, and the second index record records index information recorded in the standby service device;
the standby service device 20B determines the index information lacking in the main service device according to the first index record and the second index record;
the standby service apparatus 20B synchronizes the index information lacking in the main service apparatus with the main service apparatus.
In the embodiment of the present invention, to ensure that the information of the main service device 20A is complete, the standby service device 20B needs to synchronize the index information of the service data uploaded to the standby storage device 30B back to the main service device in time.
In the embodiment of the invention, one copy of data is stored in either the main storage device 30A or the standby storage device 30B, one copy of data is stored, and the index information of the data is stored in the main storage device and the standby storage device respectively, so that the stored data can be found no matter the index information of the data of the main service device 20A or the index information of the data of the standby service device 20B is inquired, the safety and the stability of the disaster recovery system are ensured, meanwhile, the occupation of storage resources is reduced, and the utilization rate of the storage resources is improved.

In the disaster recovery system of the embodiment of the invention, the service access module A receives the service request sent by the service server A, then sends the service request to the upload module A, and the upload module A uploads the service data to the storage module A. The service access module A monitors whether the service data is uploaded successfully, if the uploading is determined to be unsuccessful, and the uploading failure rate is determined to reach any level disaster tolerance threshold value in the multi-level disaster tolerance threshold values in the current detection period, the service access module A sends a remote retry request or a remote switching request to the uploading module B according to the disaster tolerance level corresponding to the uploading failure rate, wherein the detection period can be set according to the requirement and can be a minute granularity, and the method is not limited in the embodiment of the invention. The uploading module B uploads the service data to the storage module B according to the remote retry request or the remote switching request, and sends the index information of the service data to the uploading module A through the synchronization module A.
The service access module a can also pull the index information list of the service data from the upload module a, and the service access module B can also pull the index information list of the service data from the upload module B.
The service access module B may also query the synchronized index information and the unsynchronized index information in the synchronization module a and the synchronization module B, thereby determining the index information of all the service data that should be included in the machine room a.
If the uploading module A uploads the service data to the storage module A normally, the disaster recovery strategy is not triggered, and after the service data is uploaded normally, the synchronization module A only needs to synchronize the index information of the service data to the storage module B.
