[0057] In order to make the objectives, technical solutions and advantages of this application more clear and understandable, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0058] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data need to comply with relevant regulations.

[0059] The system recovery method provided by the embodiments of this application can be applied to, for example Figure 1 the application environment shown. Among them, the storage device 104 is physically connected to the target host 102 and the storage server 106 respectively, and the source host 108 communicates with the storage server 106 and the backup server 110 through the network respectively. Specifically, referring to Figure 1 , the backup server 110 backs up the operating system of the source host 108 to obtain the first backup set data, and sends the first backup set data to the storage server 106 through the source host 108. The storage server 106 stores the first backup set data. The target host 102 obtains the current network information. When the current network information is abnormal, the target host 102 obtains the first backup set data from the storage device 104 according to the storage path information of the first backup set data. The target host 102 responds to the backup set data recovery instruction for the operating system of the source host 108, filters out the second backup set data corresponding to the backup set data recovery instruction from the first backup set data, and restores the operating system of the source host 108 according to the second backup set data. Among them, the target host 102 can be a terminal or a server; the storage device 104 refers to a storage device that can be moved, such as a mobile hard disk, a USB flash drive, etc.; the storage server 106 refers to a server that stores the first backup set data; the source host 108 is used to represent the host that needs to perform disaster recovery, which can be a terminal or a server; the backup server 110 is a server that backs up the operating system of the source host. The terminal can be but is not limited to various personal computers, laptop computers, smart phones and tablet computers. The server can be implemented by an independent server or a server cluster composed of multiple servers.

[0060] In an exemplary embodiment, as Figure 2 shown, a system recovery method is provided. Taking the target host in Figure 1 as an example for description, the specific steps are as follows:

[0061] Step S201, obtain the current network information.

[0062] Among them, the current network information is used to characterize the network situation of the target host at the current time.

[0063] Exemplarily, the target host obtains information such as the network connection type, network latency, network bandwidth, and packet loss rate at the current time, and uses all this information as the current network information.

[0064] Step S202, in the case where the current network information is abnormal, obtain the first backup set data from the storage device according to the storage path information of the first backup set data; the first backup set data is used to represent the data obtained by backing up the operating system of the source host, and the source host is used to represent the host that needs to perform disaster recovery.

[0065] Among them, the first backup set data is used to represent the data obtained by backing up the operating system of the source host.

[0066] Among them, the operating system of the source host is a Linux (an operating system) system.

[0067] Among them, the storage path information is used to represent the storage address of the first backup set data.

[0068] Exemplarily, when the current network information of the target host is abnormal, the target host obtains the storage path information of the first backup set data; then, the target host obtains the first backup set data from the storage device according to the storage path information of the first backup set data. It should be noted that before this step (i.e., before a disaster occurs to the source host), the backup server backs up the operating system of the source host to obtain the first backup set data, and sends the first backup set data to the storage server through the source host. The storage server stores the first backup set data, and the storage device obtains the first backup set data from the storage server according to the storage path information of the first backup set data by connecting to the storage server.

[0069] Step S203, in response to the backup set data recovery instruction for the operating system of the source host, filter out the second backup set data corresponding to the backup set data recovery instruction from the first backup set data.

[0070] Among them, the backup set data recovery instruction refers to the instruction information for recovering the backup set data of the operating system of the source host.

[0071] Among them, the second backup set data refers to the backup set data corresponding to the backup set data recovery instruction.

[0072] Exemplarily, the target host receives a backup set data recovery instruction for the operating system of the source host sent by the user's terminal, and in response to the backup set data recovery instruction, filters out the backup set data corresponding to the backup set data recovery instruction from the first backup set data as the second backup set data.

[0073] Step S204: Recover the operating system of the source host according to the second backup set data.

[0074] Among them, the recovery process refers to the process of reconstructing the operating system of the source host.

[0075] Exemplarily, the target host performs an integrity check on the second backup set data to obtain the integrity check result of the second backup set data; when the integrity check result of the second backup set data indicates that the data is intact, the target host recovers the operating system of the source host according to the second backup set data.

[0076] In the above system recovery method, first obtain the current network information. When the current network information is abnormal, obtain the first backup set data from the storage device according to the storage path information of the first backup set data, and in response to the backup set data recovery instruction for the operating system of the source host, filter out the second backup set data corresponding to the backup set data recovery instruction from the first backup set data. Finally, recover the operating system of the source host according to the second backup set data. In this way, during the system recovery process, after determining that the current network information is abnormal, through the backup set data recovery instruction, immediately determine the second backup set data for recovering the operating system of the source host from the first backup set data obtained according to the storage path information, so as to quickly restore the normal operation of the operating system of the source host, thereby improving the system recovery efficiency; moreover, the entire process does not require manual intervention, avoiding the defect that the manual recovery method is prone to consume a large amount of time and manpower, resulting in a low system recovery efficiency, and further improving the system recovery efficiency.

[0077] In an exemplary embodiment, before obtaining the first backup set data from the storage device according to the storage path information of the first backup set data in the above step S202, the following specific content is included: obtain the first identification information of the source host, the second identification information of the storage pool associated with the source host, the third identification information of the first backup set data, and the backup type of the first backup set data; determine the storage path information according to the first identification information, the second identification information, the third identification information, and the backup type.

[0078] Among them, the first identification information refers to the ID (identification) of the source host, such as the MAC (Media Access Control) address, IP (Internet Protocol) address, etc. of the source host.

[0079] Among them, the storage pool associated with the source host refers to the storage pool where the first backup set data is located in the storage server associated with the source host.

[0080] Among them, the second identification information refers to the ID of the storage pool, such as the name of the storage pool.

[0081] Among them, the third identification information refers to the ID of the first backup set data, such as the backup time of the first backup set data.

[0082] Among them, the backup type is used to represent the backup form of the first backup set data, such as full backup, incremental backup, differential backup, etc.

[0083] Exemplarily, the target host obtains the first identification information of the source host, the second identification information of the storage pool associated with the source host, the third identification information of the first backup set data, and the backup type of the first backup set data; then, the target host uses the first identification information as the first-level directory information, the second identification information as the second-level directory information, the backup type as the third-level directory information, and the third identification information as the specific storage location information, and formats them according to a pre-set directory hierarchy structure and delimiter (such as " / ") to obtain formatted information, and uses this formatted information as the storage path information of the first backup set data.

[0084] For example, referring to Figure 3 , the target host uses the source host identifier as the first-level directory information, the storage pool identifier as the second-level directory information, the backup type as the third-level directory information, and the backup set identifier as the specific storage location information, and constructs the storage path information of the first backup set data (source host identifier / storage pool identifier / backup type / backup set identifier).

[0085] In this embodiment, by integrating the first identification information of the source host, the second identification information of the storage pool, the third identification information of the backup set data, and the backup type to determine the storage path information, it is possible to achieve precise management of the storage location of the backup set data, so as to reasonably allocate storage resources and improve the overall utilization rate of storage resources.

[0086] In an exemplary embodiment, in step S204 above, for restoring the operating system of the source host according to the second backup set data, the specific content is as follows: obtaining the configuration information of the operating system of the source host; and restoring the operating system of the source host according to the second backup set data and the configuration information.

[0087] Among them, the configuration information includes data network configuration of the operating system of the source host, selection of disk restoration, information on whether to ignore creating a BIOS (Basic Input Output System) boot partition during restoration, and the like.

[0088] Exemplarily, the target host uses a configuration file reading tool (such as a registry editor) to obtain the configuration information of the operating system of the source host; then, the target host filters out the configuration information with an importance level greater than a preset importance level from the configuration information as key configuration information; and then, the target host restores the operating system of the source host according to the backup set data and the key configuration information.

[0089] In this embodiment, by obtaining the original configuration information of the source host operating system and combining it with the second backup set data for restoration, it is possible to restore it to the greatest extent according to the initial settings of the source host operating system, thereby avoiding problems such as inconsistent system configuration and the original state caused by manual restoration or incomplete restoration, which is beneficial to improving the restoration accuracy of the source host operating system.

[0090] In an exemplary embodiment, in step S203 above, before filtering out the second backup set data corresponding to the backup set data restoration instruction from the first backup set data in response to the backup set data restoration instruction for the operating system of the source host, the specific content is as follows: regarding both the first backup set data and the current backup set data stored on the target host as candidate backup set data; the current backup set data is used to represent the data obtained after backing up the operating systems of other hosts; other hosts refer to hosts other than the source host.

[0091] Then, in response to the backup set data restoration instruction for the operating system of the source host, filtering out the second backup set data corresponding to the backup set data restoration instruction from the first backup set data, the specific content is as follows: in response to the backup set data restoration instruction for the operating system of the source host, filtering out the second backup set data corresponding to the backup set data restoration instruction from the candidate backup set data.

[0092] Among them, the current backup set data refers to the backup set data stored by the target host at the current time.

[0093] Among them, the candidate backup set data includes the first backup set data and the current backup set data.

[0094] Exemplarily, the target host uses the data obtained after backing up the operating systems of hosts other than the source host as the current backup set data stored by the target host; then, the target host combines the first backup set data and the current backup set data stored by the target host to obtain candidate backup set data; then, in response to a backup set data recovery instruction for the operating system of the source host, the target host filters out the second backup set data corresponding to the backup set data recovery instruction from the candidate backup set data.

[0095] It should be noted that when filtering the second backup set data, in the process of filtering the second backup set data, it is necessary to comprehensively consider the usage scenarios of the source host and other hosts to determine the most suitable second backup set data. Therefore, the current backup set data affects the filtering process of the second backup set data (for example, the current backup set data contains newer operating system patches or more optimized system configurations).

[0096] In this embodiment, by using both the first backup set data and the current backup set data stored by the target host as candidate backup set data, multiple data sources are provided for the filtering process of the second backup set data, rather than relying solely on a single backup source, which is beneficial to improving the flexibility of filtering backup set data.

[0097] In an exemplary embodiment, step S201, after obtaining the current network information, specifically includes the following: when the current network information is normal, according to the storage path information of the first backup set data, obtain the first backup set data from the storage server associated with the source host.

[0098] It should be noted that when the current network information is normal, the target host is connected to the storage server associated with the source host through the network and directly obtains the first backup set data from the storage server; when the current network information is abnormal, the target host needs to be physically connected to the storage device to indirectly obtain the first backup set data from the storage server.

[0099] Exemplarily, when the current network information of the target host is normal, a network path is established between the target host and the storage server associated with the source host; then, the target host obtains the first backup set data from the storage server associated with the source host through the network path according to the storage path information of the first backup set data.

[0100] In this embodiment, when the current network information is normal, by taking advantage of the convenience of the network and the efficiency of the storage server, the first backup set data is quickly obtained from the storage server associated with the source host, which is beneficial to reducing the data transmission time and thus improving the acquisition efficiency of the backup set data.

[0101] In an exemplary embodiment, after obtaining the current network information in step S201 above, the following specific content is included: extracting the information features of the current network information; extracting the key information features from the information features; determining the feature vector of the key information features; inputting the feature vector into the trained network information detection model to obtain the anomaly probability of the current network information; and determining that the current network information is abnormal when the anomaly probability is greater than the preset probability.

[0102] Among them, the information features of the current network information refer to the characteristic information of the current network information, such as the values corresponding to network latency and network bandwidth.

[0103] Among them, the key information features refer to the information features whose importance level is greater than the preset importance level.

[0104] Among them, the feature vector is used to represent the characterization vector of the key information features.

[0105] Among them, the network information detection model refers to a network model that can obtain the anomaly probability of the current network information, such as a convolutional neural network, etc.

[0106] Among them, the anomaly probability is used to represent the possibility that the current network information is abnormal.

[0107] Among them, the preset probability refers to the preset probability value, such as 50%.

[0108] Exemplarily, the target host extracts the information features of the current network information; then, the target host determines the importance level of the information features and filters out the information features whose importance level is greater than the preset importance level from the information features as the key information features; then, the target host inputs the key information features into the feature extraction model, and through the feature extraction model, performs feature extraction processing on the key information features to obtain the feature vector of the key information features; then, the target host inputs the feature vector into the trained network information detection model to obtain the anomaly probability corresponding to the feature vector as the anomaly probability of the current network information; finally, when the anomaly probability is greater than the preset probability, the target host determines that the current network information is abnormal; when the anomaly probability is less than or equal to the preset probability, the target host determines that the current network information is normal.

[0109] In this embodiment, through the trained network information detection model, the current network information is predicted, so that the abnormal situation of the current network information can be quickly obtained, which is beneficial to improving the determination efficiency of the abnormal situation of the current network information; moreover, the entire process does not require manual intervention, avoiding the defect that the method of manual judgment is prone to consume a lot of time and result in a low determination efficiency of the abnormal situation of the current network information.

[0110] In an exemplary embodiment, asFigure 4 As shown, another system recovery method is provided. Taking the target host in Figure 1 as an example, the method includes the following steps:

[0111] Step S401: Obtain the current network information;

[0112] Step S402: Obtain the first identification information of the source host, the second identification information of the storage pool associated with the source host, the third identification information of the first backup set data, and the backup type of the first backup set data.

[0113] Step S403: Determine the storage path information according to the first identification information, the second identification information, the third identification information, and the backup type.

[0114] Step S404: When the current network information is normal, obtain the first backup set data from the storage server associated with the source host according to the storage path information of the first backup set data.

[0115] Step S405: When the current network information is abnormal, obtain the first backup set data from the storage device according to the storage path information of the first backup set data; the first backup set data is used to represent the data obtained by backing up the operating system of the source host, and the source host is used to represent the host that needs to perform disaster recovery.

[0116] Step S406: In response to the backup set data recovery instruction for the operating system of the source host, screen out the second backup set data corresponding to the backup set data recovery instruction from the first backup set data.

[0117] Step S407: Obtain the configuration information of the operating system of the source host; according to the second backup set data and the configuration information, perform a recovery process on the operating system of the source host.

[0118] In the above system recovery method, during the process of recovering the system, after determining that the current network information is abnormal, through the backup set data recovery instruction, immediately determine the second backup set data for recovering the operating system of the source host from the first backup set data obtained according to the storage path information, so as to quickly make the operating system of the source host return to normal operation, thereby improving the system recovery efficiency; moreover, the entire process does not require manual intervention, avoiding the defect that the manual recovery method is prone to consume a large amount of time and manpower, resulting in low system recovery efficiency, and further improving the system recovery efficiency.

[0119] In an exemplary embodiment, in order to more clearly illustrate the system recovery method provided by the embodiments of the present application, the following uses a specific embodiment to specifically describe the system recovery method. In one embodiment, asFigure 5 As shown in the figure, the present application also provides a disaster recovery method for the Linux operating system. During the process of system recovery, first obtain the current network information. When the current network information is abnormal, obtain the first backup set data from the storage device according to the storage path information of the first backup set data, and in response to the backup set data recovery instruction for the operating system of the source host, screen out the second backup set data corresponding to the backup set data recovery instruction from the first backup set data. Finally, perform recovery processing on the operating system of the source host according to the second backup set data. The specific contents are as follows:

[0120] This system consists of three parts: a source host, a backup server, and a storage server. Users back up the source host by logging in to the backup server and store it in the storage server. During recovery, the operating system is recovered through network / offline and other methods. The system architecture diagram is as Figure 1 shown.

[0121] After the backup is completed, the backup set data is saved in the storage server according to a specific structure, which is convenient for searching during recovery. The storage structure is as Figure 3 shown.

[0122] After the backup is completed, the operating system can be recovered in two ways according to specific needs: network / local.

[0123] I. Network recovery: By starting the boot program on the target machine, logging in to the backup server and listing all backup sets. Select the backup set to be recovered, configure network, disk and other information, and then perform operating system recovery through network transmission.

[0124] II. Local recovery: When the network fails or the operating system needs to be recovered in an offline environment, the target machine can scan these backup set files through the boot program by physically connecting the storage device or copying and burning the backup set files with a specified storage structure to the storage medium. However, since the boot program scans the backup sets according to certain rules, the backup set files need to be stored according to the specified storage structure when copying.

[0125] The process of this system is as follows:

[0126] 1. Log in to the backup server, back up the operating system of the source host, and obtain the corresponding backup set data.

[0127] 2. Start the recovery boot program in the target host.

[0128] 3. If the network of the target host is normal, it can be directly recovered by connecting to the backup server.

[0129] 4. If the target host cannot access the network or there is a network failure, local offline recovery can be performed.

[0130] 5. Copy the backup set data of the source host operating system to the specified folder of the target host or make a physical connection with the storage device.

[0131] 6. Scan and list the backup set data on the target host disk through the recovery boot program.

[0132] 7. The user selects the specified backup set, configures relevant information, and starts the recovery.

[0133] 8. The recovery is completed.

[0134] In the above embodiments, during the process of recovering the system, after determining that the current network information is abnormal, through the backup set data recovery instruction, the second backup set data for recovering the operating system of the source host is immediately determined from the first backup set data obtained according to the storage path information, so that the operating system of the source host can be quickly restored to normal operation, thereby improving the recovery efficiency of the system; moreover, the entire process does not require manual intervention, avoiding the defect that the manual recovery method is prone to consume a large amount of time and manpower, resulting in a low recovery efficiency of the system, and further improving the recovery efficiency of the system. At the same time, compared with the existing operating system recovery solutions, this solution can recover the operating system without relying on a network connection, providing a solution for the recovery of the target host operating system for specific network requirements (such as offline, network failure, etc.).
