[0008] When a user terminal is detected to request data recovery for data to be recovered, it is determined whether the data to be recovered exists in the local data.

[0022] If local backup fails, report the error reason.

[0023] Optionally, the determination of the target off-site storage from several off-site storages based on a preset off-site backup strategy includes:

[0024] Based on the target data recovery influencing factors specified in the preset off-site backup strategy, the weight scores of the plurality of off-site storages are calculated, and the target off-site storage is determined from the plurality of off-site storages according to the score results.

[0025] Secondly, this application discloses a data backup and recovery device, comprising:

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] In the era of cloud computing, data corruption or loss can occur due to instability in equipment and network environments, as well as improper user operations, potentially leading to system crashes. Therefore, stable data backup and rapid recovery are crucial for ensuring system stability. Existing technologies mostly focus on the consistency of data across multiple nodes in distributed storage, resulting in relatively low efficiency in data backup and recovery.

[0043] Therefore, this application proposes a data backup and recovery scheme that can achieve stable data backup and rapid recovery.

[0044] This application discloses a data backup and recovery method. See also Figure 1 As shown, the method includes:

[0045] Step S11: Obtain the feature information of the user terminal's customized data to be backed up, and perform local backup of the corresponding data to be backed up based on the feature information.

[0046] It should be noted that this embodiment can obtain the characteristic information of the user terminal's customized data to be backed up, and perform local backup of the corresponding data based on the characteristic information. In this way, backing up data according to the customized characteristic information can solve the problem of large data volume, improve backup speed, and save storage space.

[0047] In this embodiment, the backup method is first determined, wherein the backup method includes a single backup or a scheduled periodic backup; correspondingly, the local backup of the corresponding data to be backed up based on the feature information includes: performing a local backup of the corresponding data to be backed up based on the backup method and the feature information. In one specific implementation, a local single backup of the corresponding data to be backed up is performed based on the feature information; in another specific implementation, a local scheduled periodic backup of the corresponding data to be backed up is performed based on the feature information. In this way, this embodiment can select the backup method to adapt to actual business needs.

[0048] It should be noted that the local backup of the corresponding data to be backed up based on the feature information may specifically include: performing local backup of the corresponding data to be backed up based on the feature information and setting an effective backup time. In this way, this application can clean up the data in the local machine according to the effective backup time, saving disk space.

[0049] Step S12: Based on a preset off-site backup strategy, determine the target off-site storage from several off-site storages, back up the data to be backed up in the target off-site storage, and then complete the synchronization of the data to be backed up in other off-site storages.

[0050] In this embodiment, based on the target data recovery influencing factors specified in the preset off-site backup strategy, the weight scores of the plurality of off-site storages are calculated, and the target off-site storage is determined from the plurality of off-site storages according to the score results. The target data recovery influencing factors include, but are not limited to, factors affecting data recovery such as network and region. It can be understood that by calculating the weight scores of the plurality of off-site storages through the above-mentioned factors affecting data recovery, and determining the target off-site storage from the plurality of off-site storages according to the score results, this embodiment enables data to be uploaded to the target off-site storage at a faster speed.

[0051] Step S13: When a user terminal is detected to request data recovery for the data to be recovered, it is determined whether the data to be recovered exists in the local data. If it does, the corresponding data recovery is performed based on the local data. If not, a new target off-site storage is determined from several off-site storages based on the preset off-site backup strategy, and the corresponding data recovery is performed using the new target off-site storage.

[0052] In this embodiment, when a user terminal's data recovery request for data to be recovered is detected, it is determined whether the data to be recovered exists in the local data. If the data to be recovered exists in the local data, corresponding data recovery is performed based on the local data. If the data to be recovered does not exist in the local data, a new target off-site storage is determined from several off-site storages based on the preset off-site backup strategy, and corresponding data recovery is performed using the new target off-site storage. For example, since the local server has limited capacity, an effective backup time is set, and data outside the effective backup time is cleaned up to save disk space. Suppose the effective backup time for local data is 3 months, but the user terminal wants to obtain 1 year's worth of backup data. In this case, the backup data does not exist locally, so a new target off-site storage needs to be determined from several off-site storages based on the preset off-site backup strategy, and corresponding data recovery is performed using the data in the new target off-site storage.

[0053] As can be seen, this application proposes a data backup and recovery method, including: obtaining characteristic information of data to be backed up by a user terminal, and performing local backup of the corresponding data based on the characteristic information; determining a target off-site storage from several off-site storages based on a preset off-site backup strategy, and backing up the data to be backed up in the target off-site storage, and then synchronizing the data to be backed up in other off-site storages; when a data recovery request for data to be recovered is detected from a user terminal, determining whether the data to be recovered exists in the local data, and if so, performing corresponding data recovery based on the local data; if not, determining a new target off-site storage from several off-site storages based on the preset off-site backup strategy, and performing corresponding data recovery using the new target off-site storage. Therefore, this application performs backups both locally and off-site, ensuring stable data backup; when recovering data, it first performs recovery based on the local data, and if the data does not exist locally, it selects a target off-site storage for data recovery based on the preset off-site backup strategy, thereby ensuring rapid data recovery.

[0054] This application discloses a specific data backup and recovery method. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution. See also... Figure 2As shown, it specifically includes:

[0055] Step S21: Obtain the type and range of data to be backed up as defined by the user terminal, and perform local backup of the corresponding data based on the type and range.

[0056] It should be noted that this embodiment can obtain the type and range of data to be backed up as defined by the user terminal, and perform local backup of the corresponding data based on the type and range. In this way, backing up data according to the customized data type and range can solve the problem of large data volume, improve backup speed, and save storage space.

[0057] Step S22: Determine whether the local backup was successful; if the local backup was successful, execute the step of determining the target off-site storage from several off-site storages based on the preset off-site backup strategy. If the local backup failed, report the error reason.

[0058] In this embodiment, after local backup, the process further includes: determining whether the local backup was successful; if the local backup was successful, then executing the step of determining the target off-site storage from several off-site storages based on a preset off-site backup strategy; if the local backup failed, then reporting the reason for the error. That is, in this embodiment, after a successful local backup, an off-site backup is performed, and if the local backup fails, the reason for the backup failure must be reported.

[0059] Step S23: Based on a preset off-site backup strategy, determine the target off-site storage from several off-site storages, back up the data to be backed up in the target off-site storage, and then complete the synchronization of the data to be backed up in other off-site storages.

[0060] Step S24: When a data recovery request for data to be recovered is detected from a user terminal, it is determined whether the data to be recovered exists in the local data. If it does, the corresponding data recovery is performed based on the local data. If not, a new target off-site storage is determined from several off-site storages based on the preset off-site backup strategy, and the corresponding data recovery is performed using the new target off-site storage.

[0061] For more detailed information on steps S23 and S24, please refer to the aforementioned disclosed embodiments, which will not be elaborated upon here.

[0062] As can be seen, this application proposes a data backup and recovery method, including: obtaining the type and range of data to be backed up as defined by a user terminal, and performing local backup of the corresponding data based on the type and range; determining whether the local backup is successful; if the local backup is successful, executing the step of determining a target off-site storage from several off-site storages based on a preset off-site backup strategy; if the local backup fails, reporting the error reason; determining a target off-site storage from several off-site storages based on the preset off-site backup strategy, and backing up the data to be backed up in the target off-site storage, and then synchronizing the data to be backed up in other off-site storages; when a user is detected... When a terminal receives a data recovery request for data to be recovered, it determines whether the data to be recovered exists in the local data. If it does, it performs corresponding data recovery based on the local data. If not, it determines a new target off-site storage from several off-site storages based on the preset off-site backup strategy and performs corresponding data recovery using the new target off-site storage. Thus, this application performs backups on both local and off-site storage when backing up data, ensuring stable data backup. When recovering data, it first performs recovery based on the local data. If the data does not exist locally, it selects a target off-site storage for data recovery based on the preset off-site backup strategy, thereby ensuring rapid data recovery.

[0063] Based on the aforementioned data backup and recovery method, this application specifically includes a local storage device, a remote storage device, and a selection device. Specifically, this application first selects the type and scope of backup data using the selection device, then uses the local storage device to store the backup data locally and sets a corresponding validity period to clean up expired data and save disk space. After local backup is complete, the selection device calculates the weights of each remote storage device using a user-defined selection strategy or a default strategy, sorts them according to their calculated scores, and selects the optimal remote storage device based on the sorting results. The remote storage device is distributed storage. The default strategy is a strategy based on factors affecting data recovery, such as network and regional factors. After the optimal remote storage device completes backup, other available remote storage devices are asynchronously notified to perform incremental or full backups of the data. After backup is complete, a callback is sent to inform the user of the execution result, thus completing the entire backup process.

[0064] When data recovery is required, it is determined whether the data to be recovered exists in the local storage device. If it does, the local data is used directly for data recovery. If not, the selection device is entered. Based on the default policy, the best storage device containing the data is selected for data recovery.

[0065] Based on the aforementioned local storage device, off-site storage device, and selection device, this application, in a specific embodiment, specifically includes the following:

[0066] See Figure 3 As shown, when performing data backup, the user terminal can customize the types and categories of data to be backed up according to specific business needs, and set up manual single backup or scheduled periodic backup. This further ensures data integrity and prevents data loss. It triggers the local storage device to perform local backup and records the data's validity period for subsequent cleanup of redundant data. After the local backup is complete, it determines whether the backup was successful. If not, it reports the error reason; if successful, it uses a selection device and selects the optimal off-site storage device for off-site backup based on different selection strategies. Selection strategies include user-defined strategies and default strategies. The default strategy is based on factors affecting data recovery, such as network and region. After the backup is complete, it notifies other asynchronous storage devices to perform incremental or full backups.

[0067] See Figure 4 As shown, when performing data recovery, users can select the data to be recovered, or default to recovering the latest backup data; the system searches the local storage device to see if the data to be recovered is present. If it is, the recovery operation is performed directly; if not, the selection device is used to select the optimal off-site storage device according to different selection strategies, thereby remotely pulling the data for recovery.

[0068] Therefore, to improve data recovery speed, this application introduces a local storage device and prioritizes the use of data from this device for recovery; furthermore, by setting a reasonable selection strategy, the optimal storage device is chosen to improve data recovery speed. In addition, it should be noted that distributed geographically distributed storage devices can synchronize data through various methods such as manual synchronization, scheduled synchronization, and restart synchronization, thereby ensuring data consistency.

[0069] Accordingly, this application also discloses a data backup and recovery device, see [link to relevant documentation]. Figure 5 As shown, the device includes:

[0070] The local backup module 11 is used to obtain the feature information of the data to be backed up by the user terminal and perform local backup of the corresponding data to be backed up based on the feature information.

[0071] It should be noted that this embodiment can obtain the characteristic information of the user terminal's customized data to be backed up, and perform local backup of the corresponding data based on the characteristic information. In this way, backing up data according to the customized characteristic information can solve the problem of large data volume, improve backup speed, and save storage space.

[0072] The off-site backup module 12 is used to determine the target off-site storage from several off-site storages based on a preset off-site backup strategy, back up the data to be backed up in the target off-site storage, and then complete the synchronization of the data to be backed up in other off-site storages.

[0073] The data recovery module 13 is used to determine whether the data to be recovered exists in the local data when a data recovery request for the data to be recovered is detected from the user terminal. If it exists, the corresponding data recovery is performed based on the local data. If it does not exist, a new target off-site storage is determined from several off-site storages based on the preset off-site backup strategy, and the corresponding data recovery is performed using the new target off-site storage.

[0074] When a user terminal's data recovery request for data to be recovered is detected, it is determined whether the data to be recovered exists in the local data. If the data to be recovered exists in the local data, corresponding data recovery is performed based on the local data. If the data to be recovered does not exist in the local data, a new target off-site storage is determined from several off-site storages based on the preset off-site backup strategy, and corresponding data recovery is performed using the new target off-site storage. For example, due to the limited capacity of the local server, an effective backup time is set, and data outside the effective backup time is cleaned up to save disk space. Suppose the effective backup time of the local data is 3 months, but the user terminal wants to obtain 1 year's worth of backup data. In this case, the backup data does not exist locally, so a new target off-site storage needs to be determined from several off-site storages based on the preset off-site backup strategy, and corresponding data recovery is performed using the data in the new target off-site storage.

[0075] As can be seen, this application proposes a data backup and recovery method, including: obtaining characteristic information of data to be backed up by a user terminal, and performing local backup of the corresponding data based on the characteristic information; determining a target off-site storage from several off-site storages based on a preset off-site backup strategy, and backing up the data to be backed up in the target off-site storage, and then synchronizing the data to be backed up in other off-site storages; when a data recovery request for data to be recovered is detected from a user terminal, determining whether the data to be recovered exists in the local data, and if so, performing corresponding data recovery based on the local data; if not, determining a new target off-site storage from several off-site storages based on the preset off-site backup strategy, and performing corresponding data recovery using the new target off-site storage. Therefore, this application performs backups both locally and off-site, ensuring stable data backup; when recovering data, it first performs recovery based on the local data, and if the data does not exist locally, it selects a target off-site storage for data recovery based on the preset off-site backup strategy, thereby ensuring rapid data recovery.

[0076] In some specific embodiments, the local backup module 11 may specifically include:

[0078] In some specific embodiments, after the local backup module 11, there may also be:

[0079] A backup method determination unit is used to determine the backup method, wherein the backup method includes a single backup or a scheduled periodic backup.

[0082] In one specific implementation, a local single backup is performed on the corresponding data to be backed up based on the feature information; in another specific implementation, a local periodic backup is performed on the corresponding data to be backed up based on the feature information. In this way, this embodiment can select the backup method to adapt to actual business needs.

[0083] In some specific embodiments, the local backup module 11 may specifically include:

[0084] The effective backup time setting unit is used to perform local backup of the corresponding data to be backed up based on the feature information and set the effective backup time.

[0085] Based on the aforementioned feature information, the corresponding data to be backed up is backed up locally, and an effective backup time is set. In this way, the present application can clean up the data in the local storage according to the effective backup time, thereby saving disk space.

[0086] In some specific embodiments, the data backup and recovery may further include:

[0087] The data cleaning unit is used to clean up the data in the local machine according to the effective backup time.

[0088] In some specific embodiments, after the local backup module 11, it may further include:

[0089] The backup result judgment unit is used to determine whether the local backup is successful; if the local backup is successful, the step of determining the target off-site storage from several off-site storages based on the preset off-site backup strategy is executed; if the local backup fails, the error reason is reported.

[0090] After performing local backup of the corresponding data to be backed up based on the feature information, the method further includes: determining whether the local backup was successful; if the local backup was successful, executing the step of determining the target off-site storage from several off-site storages based on the preset off-site backup strategy; if the local backup failed, reporting the error reason.

[0093] It is understandable that by calculating the weight scores of the aforementioned factors affecting data recovery, and determining the target off-site storage from among the aforementioned off-site storage based on the score results, this embodiment enables data to be uploaded to the target off-site storage at a faster speed.

Claims

1. A data backup and recovery method, characterized in that, include: Obtain the feature information of the user terminal's customized data to be backed up, and perform local backup of the corresponding data based on the feature information; Based on a preset off-site backup strategy, a target off-site storage is determined from several off-site storages, and the data to be backed up is backed up in the target off-site storage. Then, the data to be backed up is synchronized in other off-site storages. When a user terminal is detected to request data recovery for data to be recovered, it is determined whether the data to be recovered exists in the local data. If it does, the corresponding data recovery is performed based on the local data. If not, a new target off-site storage is determined from several off-site storages based on the preset off-site backup strategy, and the corresponding data recovery is performed using the new target off-site storage. The step of determining the target off-site storage from several off-site storage locations based on a preset off-site backup strategy includes: Based on the target data recovery influencing factors specified in the preset off-site backup strategy, the weight scores of the plurality of off-site storages are calculated, and the target off-site storage is determined from the plurality of off-site storages according to the score results. The preset off-site backup strategy is either a user-defined selection strategy or a default strategy based on factors affecting data recovery such as network and regional factors. The multiple off-site storages are distributed storage. After the target off-site storage completes the backup, other available off-site storages are asynchronously notified to perform incremental or full backups of the data to be backed up. The other available off-site storages then notify the execution result via callback after the backup is completed.

2. The data backup and recovery method according to claim 1, characterized in that, The step of obtaining the feature information of the user terminal's customized data to be backed up, and performing local backup of the corresponding data based on the feature information, includes: Obtain the type and range of data to be backed up as defined by the user terminal, and perform local backup of the corresponding data based on the type and range.

3. The data backup and recovery method according to claim 1, characterized in that, After obtaining the characteristic information of the user terminal's customized data to be backed up, the method further includes: Determine the backup method, wherein the backup method includes single backup or scheduled periodic backup; Accordingly, the step of performing local backup of the corresponding data to be backed up based on the feature information includes: Based on the backup method and the feature information, the corresponding data to be backed up is backed up locally.
