Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The server 104 responds to the data recovery instruction, queries the target backup data from the backup database corresponding to the data recovery instruction, and obtains the business parameters in the data recovery instruction; restores the target backup data to the target storage space, and uses the business parameters to establish the business process corresponding to the target backup data, wherein the target backup data is used to participate in the business process; when it is detected that the target backup data has been restored and the business process has been established, the data identifier of the target backup data in the target storage space is modified from the backup data identifier to the restored data identifier. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head mounted device may be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 104 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0038] In an exemplary embodiment, Figure 2 As shown, a backup data recovery method is provided, which is applied to Figure 1 The server 104 in the example is used as an example to illustrate the method, which includes the following steps 202 to 206. Among them:

[0039] Step 202: In response to the data recovery instruction, query the target backup data from the backup database corresponding to the data recovery instruction, and obtain the service parameters in the data recovery instruction.

[0040] Among them, the data recovery instruction in step 202 can be initiated by the user on demand. Specifically, the user operates the user interface and generates a data recovery instruction when a preset data recovery operation is detected. The data recovery instruction can also be automatically generated when the preset conditions are met. Specifically, when data call failure information is detected, a data recovery instruction is generated according to the data call failure information. The data call failure information is used to characterize the information that the data call failed due to the non-existence of the data; the data recovery instruction carries a data identifier, which is a unique identifier; the target backup data can be one or more, and there is no limitation here.

[0041] Exemplarily, querying the target backup data from the backup database corresponding to the data recovery instruction includes: querying the backup database to obtain the target backup data according to the data identifier carried in the data recovery instruction.

[0042] As an example, refer to Figure 3 The backup data recovery system is deployed on the server 104. The backup data recovery system includes a data recovery layer, a business recovery layer and a management control layer. The data recovery layer and the business recovery layer communicate with the management control layer respectively. The backup data recovery system also includes a cloud management interaction access layer. The cloud management interaction access layer communicates with the data recovery layer and the business recovery layer respectively. The cloud management interaction access layer communicates with the user interface. In response to the data recovery instruction, the target backup data is queried from the backup database corresponding to the data recovery instruction, and the business parameters in the data recovery instruction are obtained, including: responding to the data recovery instruction initiated by the user interface through the cloud management interaction access layer, querying the backup database to obtain the target backup data according to the data identifier carried by the data recovery instruction, and obtaining the business parameters carried by the data recovery instruction.

[0043] Step 204 , restore the target backup data to the target storage space, and establish a business process corresponding to the target backup data using the business parameters, wherein the target backup data is used to participate in the business process.

[0044] Exemplarily, restoring the target backup data to the target storage space includes: determining the target storage space and the corresponding target restoration queue corresponding to the target backup data, and restoring the target backup data to the target storage space through the target restoration queue.

[0045] Exemplarily, establishing a business process corresponding to target backup data using business parameters includes: obtaining correlation coefficients between business parameters and multiple existing business processes respectively, and when there are associated business processes with corresponding correlation coefficients greater than a preset correlation coefficient threshold among the multiple existing business processes, updating the associated business processes according to the business parameters to obtain the business process corresponding to the target backup data; when there are no associated business processes with corresponding correlation coefficients greater than the preset correlation coefficient threshold among the multiple existing business processes, constructing a new business process according to the business parameters to obtain the business process corresponding to the target backup data, wherein the preset correlation coefficient threshold is a correlation coefficient critical value set on demand to determine whether there is an association between the business parameters and the existing business processes.

[0046] The calculation method of the correlation coefficient includes but is not limited to the calculation method of the Pearson correlation coefficient, the calculation method of the Spearman correlation coefficient, the calculation method of the cosine distance correlation coefficient, etc.

[0047] Step 206: When it is detected that the target backup data has been restored and the business process has been established, the data identifier of the target backup data in the target storage space is modified from the backup data identifier to the restored data identifier.

[0048] Among them, the data identifier in step 206 includes at least one of a backed-up data identifier, a backup data identifier and a restored data identifier. The backed-up data identifier represents a state in which the data has been backed up and has not been deleted; the backup data identifier represents a state in which the data has been backed up and has been deleted; and the restored data identifier represents a state in which the data has been restored after being deleted.

[0049] In the above backup data recovery method, by responding to the data recovery instruction, the target backup data is queried from the backup database corresponding to the data recovery instruction, and the business parameters in the data recovery instruction are obtained; the target backup data is restored to the target storage space, and the business process corresponding to the target backup data is established using the business parameters, wherein the target backup data is used to participate in the business process; when it is detected that the target backup data has been restored and the business process has been established, the data identifier of the target backup data in the target storage space is modified from the backup data identifier to the restored data identifier, and the automatic data level recovery of the target backup data and the business function level recovery of the target backup data are processed in parallel, and when it is detected that the data level and the business function level have been restored, the data identifier of the target backup data is modified in time, so as to realize the automatic multi-threaded recovery of the target backup data, save the time spent by professionals in writing code for each target backup data, and improve the efficiency of data recovery.

[0050] In an exemplary embodiment, Figure 4 As shown, a method for accurately restoring data is provided, and restoring the target backup data to the target storage space includes steps 302 to 306. Among them:

[0051] Step 302: Select a target storage space corresponding to the target backup data from preset storage spaces, wherein the preset storage space includes at least one of a newly created storage space and an existing storage space.

[0052] The newly created storage space in step 302 may be a newly created host or a newly created cloud disk, and the existing storage space may be an existing host or an existing cloud disk, which is not limited here.

[0053] Exemplarily, step 302 includes: obtaining a user selection instruction for a preset storage space, and selecting a target storage space corresponding to the target backup data from the preset storage space according to the selection instruction; or, selecting a target storage space corresponding to the target backup data from the preset storage space according to storage space information of the preset storage space.

[0054] Further, as an embodiment, obtaining the user's selection instructions for the preset storage space includes: obtaining the user's selection instructions for the preset storage space sent by the user interface through the cloud management interactive access layer, and sending the user's selection instructions for the preset storage space to the data recovery layer, and obtaining the user's selection instructions for the preset storage space sent by the cloud management interactive access layer through the data recovery layer.

[0055] Further, as an embodiment, the storage space information of the preset storage space includes storage processing information of the existing storage space; based on the storage space information of the preset storage space, the target storage space corresponding to the target backup data is selected from the preset storage space, including: based on the storage processing information of the existing storage space, the storage status of the existing storage space is evaluated to obtain storage status evaluation information; when the storage status evaluation information meets the preset storage status condition, the existing storage space is determined as the target storage space corresponding to the target backup data; when the storage status evaluation information does not meet the preset storage status condition, the newly created storage space is determined as the target storage space corresponding to the target backup data.

[0056] As an embodiment, based on the storage processing information of the existing storage space, the storage status of the existing storage space is evaluated to obtain storage status evaluation information, including: the storage processing information includes the remaining storage memory information and the processing information, wherein the processing information is used to characterize the object task processing frequency and the object task processing quantity of the existing storage space; based on the remaining storage memory information and the processing information of the existing storage space, the storage status of the existing storage space is evaluated to obtain storage status evaluation information, wherein the storage status evaluation information can characterize the storage congestion degree of the existing storage space, the larger the remaining storage memory amount represented by the remaining storage memory information, the lower the storage congestion degree of the existing storage space represented by the storage status evaluation information; the lower the object task processing frequency of the existing storage space represented by the processing information, the lower the storage congestion degree of the existing storage space represented by the storage status evaluation information; the lower the object task processing quantity of the existing storage space represented by the processing information, the lower the storage congestion degree of the existing storage space represented by the storage status evaluation information.

[0057] In this way, if the target backup data is to be restored to the existing storage space, it will affect the object task processing process of the existing storage space. Taking into account the impact of the object task processing frequency and the number of object task processing in the existing storage space on the importance and complexity of the object task processing process, the object task processing frequency and the number of object task processing in the existing storage space are used as the basis for evaluating the storage congestion of the existing storage space. When the object task processing frequency of the existing storage space is high, that is, the importance of the object processing task process of the existing storage space is high, and / or when the number of task processing in the existing storage space is large, that is, the complexity of the object processing task process of the existing storage space is high, storage status assessment information representing that the storage congestion of the existing storage space is high is generated, so that the existing storage space is not determined as the target storage space corresponding to the target backup data, thereby ensuring the normal progress of the object task processing process of the existing storage space.

[0058] Optionally, the method also includes: if it is detected that the storage congestion level of the existing storage space represented by the storage status assessment information is less than a preset congestion level threshold, then determining that the storage status assessment information meets the preset storage status condition; if it is detected that the storage congestion level of the existing storage space represented by the storage status assessment information is not less than a preset congestion level threshold, then determining that the storage status assessment information does not meet the preset storage status condition, wherein the preset congestion level threshold is a storage congestion level critical value set on demand for determining that the storage of the existing storage space is not congested.

[0059] As one embodiment, the newly created storage space is determined as the target storage space corresponding to the target backup data, including: the storage space information of the preset storage space also includes storage cost information of multiple newly created storage spaces, and based on the storage cost information of the multiple newly created storage spaces, the target storage space corresponding to the target backup data is selected from the multiple newly created storage spaces. Specifically, the target storage space whose corresponding storage cost information meets the preset cost conditions is selected from the multiple newly created storage spaces.

[0060] Optionally, the preset cost condition may be that the cost of the representation is higher than a preset cost threshold, which is a cost critical value set on demand for determining that the cost of creating a new storage space is low; the preset cost condition may also be that the cost of the representation is the lowest value among the costs of all new storage space representations.

[0061] In this way, considering that the costs of multiple newly created storage spaces may be different, the storage cost information of the multiple newly created storage spaces is used as the basis for selecting a target storage space from the multiple newly created storage spaces, thereby ensuring low cost of data recovery.

[0062] Step 304 : selecting a target restoration queue corresponding to the target backup data from a plurality of preset processing queues according to the restoration processing logic of the target backup data.

[0063] Exemplarily, step 304 includes: obtaining preset processing logics of multiple preset processing queues; and selecting a target recovery queue whose corresponding preset processing logic matches the recovery processing logic from the multiple preset processing queues.

[0064] Furthermore, before selecting a target recovery queue whose corresponding preset processing logic matches the recovery processing logic from multiple preset processing queues, the method also includes: obtaining the similarity between the recovery processing logic and the preset processing logics corresponding to the multiple preset processing queues respectively, and determining the matching degree between the recovery processing logic and the preset processing logics corresponding to the multiple preset processing queues respectively according to the similarity between the recovery processing logic and the preset processing logics corresponding to the multiple preset processing queues respectively, wherein the higher the similarity, the higher the matching degree.

[0065] Step 306: restore the target backup data to the target storage space through the target recovery queue.

[0066] Exemplarily, the target backup data includes multiple target backup sub-data; step 306 includes: obtaining the associations between the multiple target backup sub-data and the data stored in the target storage space; determining the storage paths in which the multiple target backup sub-data are respectively stored in the target storage space based on the associations between the multiple target backup sub-data and the data stored in the target storage space; constructing a storage mapping relationship based on the storage paths in which the multiple target backup sub-data are respectively stored in the target storage space, and restoring the target backup data to the target storage space by executing the storage mapping relationship.

[0067] As one embodiment, obtaining the associations between multiple target backup sub-data and the data stored in the target storage space includes: obtaining correlation coefficients between multiple target backup sub-data and the data stored in the target storage space, and determining the correlation coefficients between multiple target backup sub-data and the data stored in the target storage space as the associations between multiple target backup sub-data and the data stored in the target storage space.

[0068] The calculation method of the correlation coefficient includes but is not limited to the calculation method of the Pearson correlation coefficient, the calculation method of the Spearman correlation coefficient, the calculation method of the cosine distance correlation coefficient, etc.

[0069] As an embodiment, based on the associations between multiple target backup sub-data and the data stored in the target storage space, the storage paths corresponding to the storage of the multiple target backup sub-data in the target storage space are determined, including: for each target backup sub-data in the multiple target backup sub-data, the corresponding target stored data whose association meets the preset association condition is selected from the stored data in the target storage space, and based on the storage path corresponding to the target stored data, the storage path corresponding to the storage of the target backup sub-data in the target storage space is determined.

[0070] Among them, the preset correlation condition can be greater than a preset correlation threshold, and the preset correlation threshold is a correlation critical value set as needed when determining that there is a strong correlation between the target backup sub-data and the stored data; the preset correlation condition can also be the maximum value among all correlations.

[0071] As an embodiment, determining the storage path corresponding to the target backup sub-data stored in the target storage space according to the storage path corresponding to the target stored data includes: determining the storage path corresponding to the target stored data as the storage path corresponding to the target backup sub-data stored in the target storage space.

[0072] In this way, it can be ensured that when the target backup sub-data is restored and stored, the storage path of the target stored data with a strong correlation therewith is the same.

[0073] As another embodiment, according to the storage path corresponding to the target stored data, the storage path corresponding to the target backup sub-data stored in the target storage space is determined, including: the storage path corresponding to the target stored data includes a first parent storage node and a first child storage node, wherein the parent storage node may include multiple nodes connected in sequence, or may include a single node, the child storage node may include multiple nodes connected in sequence, or may include a single node, and the storage path corresponding to the target backup sub-data stored in the target storage space includes a second parent storage node and a second child storage node; the first parent storage node is determined as the second parent storage node, and other child storage nodes corresponding to the first parent storage node that are different from the first child storage node are determined as second child storage nodes.

[0074] In this way, it can be ensured that when the target backup sub-data is restored and stored, the storage path of the target stored data with a strong correlation therewith is close to that of the target stored data.

[0075] As an embodiment, after restoring the target backup data to the target storage space by executing the storage mapping relationship, the method also includes: if it is detected that multiple target backup sub-data have been restored, deleting the multiple target backup sub-data pulled from the target recovery queue, and deleting the storage mapping relationship.

[0076] In this way, not only can the target recovery queue be prevented from being occupied by redundant data, and the data recovery layer from being occupied by redundant data, but also the subsequent execution of the storage mapping relationship can be avoided, resulting in repeated recovery of part of the data.

[0077] As an example, refer to Figure 5 The data recovery layer includes a data flow control component, an overall process control component and a data mapping component; the overall process control component controls the data flow control component to obtain the target backup data sent by the cloud management interactive access layer; the overall process control component controls the data mapping component to build and execute the storage mapping relationship according to the target backup data.

[0078] In this embodiment, a target storage space corresponding to the target backup data is selected from a preset storage space, wherein the preset storage space includes at least one of a newly created storage space and an existing storage space; according to the recovery processing logic of the target backup data, a target recovery queue corresponding to the target backup data is selected from multiple preset processing queues; and the target backup data is restored to the target storage space through the target recovery queue, thereby ensuring that the selected target storage space and target recovery queue are accurate, thereby achieving accurate recovery of the target backup data.

[0079] As a detailed embodiment, in response to a data recovery instruction, the target backup data is queried from the backup database corresponding to the data recovery instruction, and the business parameters in the data recovery instruction are obtained; the user's selection instruction for the preset storage space is obtained, and according to the selection instruction, the target storage space corresponding to the target backup data is selected from the preset storage space; or, according to the storage processing information of the existing storage space, the storage status of the existing storage space is evaluated to obtain storage status evaluation information; when the storage status evaluation information meets the preset storage status condition, the existing storage space is determined as the target storage space corresponding to the target backup data; when the storage status evaluation information does not meet the preset storage status condition, the newly created storage space is determined as the target storage space corresponding to the target backup data; according to the recovery processing logic of the target backup data, the target recovery queue corresponding to the target backup data is selected from multiple preset processing queues.

[0080] Furthermore, the associations between the multiple target backup sub-data and the data stored in the target storage space are obtained; based on the associations between the multiple target backup sub-data and the data stored in the target storage space, the storage paths of the multiple target backup sub-data corresponding to the storage in the target storage space are determined; based on the storage paths of the multiple target backup sub-data corresponding to the storage in the target storage space, a storage mapping relationship is constructed, and the target backup data is restored to the target storage space by executing the storage mapping relationship; if it is detected that the multiple target backup sub-data have been restored, the multiple target backup sub-data pulled from the target recovery queue are deleted, and the business process corresponding to the target backup data is established using the business parameters; when it is detected that the target backup data has been restored and the business process has been established, the data identifier of the target backup data in the target storage space is changed from the backup data identifier to the restored data identifier.

[0081] In this way, by responding to the data recovery instruction, the target backup data is queried from the backup database corresponding to the data recovery instruction, and the business parameters in the data recovery instruction are obtained; the target backup data is restored to the target storage space, and the business process corresponding to the target backup data is established using the business parameters, wherein the target backup data is used to participate in the business process; when it is detected that the target backup data has been restored and the business process has been established, the data identifier of the target backup data in the target storage space is modified from the backup data identifier to the restored data identifier, and the automatic data-level recovery of the target backup data and the business-function-level recovery of the target backup data are processed in parallel, and when it is detected that both the data-level and the business-function-level recovery are completed, the data identifier of the target backup data is modified in time, so as to realize the automatic multi-threaded recovery of the target backup data, save the time spent by professionals in writing code for each target backup data, and improve the efficiency of data recovery.

[0082] Furthermore, by selecting a target storage space corresponding to the target backup data from a preset storage space, wherein the preset storage space includes at least one of a newly created storage space and an existing storage space; according to the recovery processing logic of the target backup data, a target recovery queue corresponding to the target backup data is selected from multiple preset processing queues; and the target backup data is restored to the target storage space through the target recovery queue, thereby ensuring that the selected target storage space and target recovery queue are accurate, thereby achieving accurate recovery of the target backup data.
