[0057] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0059] The system recovery method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown in FIG. 1 , 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. 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 recovers 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 mobile storage device, such as a mobile hard disk, a USB flash drive, etc.; the storage server 106 refers to a server storing the first backup set data; the source host 108 is used to represent the host that needs to be recovered from a disaster, which can be a terminal or a server; the backup server 110 refers to a server that backs up the operating system of the source host. The terminal can be, but is not limited to, various personal computers, laptops, smart phones, and tablet computers. The server can be implemented as an independent server or a server cluster consisting of multiple servers.

[0060] In an exemplary embodiment, Figure 2 As shown, a system recovery method is provided, which is applied to Figure 1 The target host in is taken as an example to illustrate the following steps:

[0061] Step S201, obtaining current network information.

[0062] The current network information is used to represent the network status of the target host at the current time.

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

[0064] Step S202, 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.

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

[0066] The operating system of the source host is Linux (an operating system).

[0067] The storage path information is used to indicate the storage address of the first backup set data.

[0068] Exemplarily, when the current network information 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 the 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 of the operating system of the source host, second backup set data corresponding to the backup set data recovery instruction is screened out from the first backup set data.

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

[0071] 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: restore the operating system of the source host according to the second backup set data.

[0074] The recovery process refers to the process of rebuilding the operating system of the source host.

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

[0076] In the above system recovery method, the current network information is first obtained. When the current network information is abnormal, the first backup set data is obtained 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, the second backup set data corresponding to the backup set data recovery instruction is screened out from the first backup set data. Finally, the operating system of the source host is recovered according to the second backup set data. In this way, in the process of recovering the system, after determining that the current network information is abnormal, the backup set data recovery instruction is used to 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 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 whole process does not require manual intervention, avoiding the defect that the manual recovery method is easy to consume a lot of time and manpower, resulting in low system recovery efficiency, and further improving the recovery efficiency of the system.

[0077] In an exemplary embodiment, the above-mentioned step S202, before obtaining the first backup set data from the storage device according to the storage path information of the first backup set data, specifically includes the following contents: obtaining 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; determining the storage path information according to the first identification information, the second identification information, the third identification information and the backup type.

[0078] 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] 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] The second identification information refers to the ID of the storage pool, such as the name of the storage pool.

[0081] 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] The backup type is used to indicate 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 it according to a pre-set directory hierarchy structure and separator (such as " / ") to obtain formatted information, and uses the formatted information as the storage path information of the first backup set data.

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

[0085] In this embodiment, the storage path information is determined 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, so that accurate management of the storage location of the backup set data can be achieved, thereby reasonably allocating storage resources and improving the overall utilization of storage resources.

[0086] In an exemplary embodiment, the above step S204, based on the second backup set data, restores the operating system of the source host, specifically includes the following contents: obtaining the configuration information of the operating system of the source host; and restoring the operating system of the source host based on the second backup set data and the configuration information.

[0087] The configuration information includes the data network configuration of the operating system of the source host, the choice of disk recovery, whether to ignore the creation of the BIOS (Basic Input Output System) boot partition during recovery, and other information.

[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 configuration information whose importance is greater than a preset importance from the configuration information as key configuration information; then, the target host restores the operating system of the source host based on 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 restoring it in combination with the second backup set data, it is possible to restore it to the greatest extent possible in accordance with the original settings of the source host operating system, thereby avoiding the problem of inconsistency between the system configuration and the original state caused by manual recovery or incomplete recovery, which is beneficial to improving the recovery accuracy of the source host operating system.

[0090] In an exemplary embodiment, the above-mentioned step S203, before responding to the backup set data recovery instruction for the operating system of the source host and filtering out the second backup set data corresponding to the backup set data recovery instruction from the first backup set data, specifically includes the following contents: the first backup set data and the current backup set data stored in the target host are both used 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 represent hosts other than the source host.

[0091] Then, in response to the backup set data recovery instruction for the operating system of the source host, the second backup set data corresponding to the backup set data recovery instruction is filtered out from the first backup set data, which specifically includes the following contents: In response to the backup set data recovery instruction for the operating system of the source host, the second backup set data corresponding to the backup set data recovery instruction is filtered out from the candidate backup set data.

[0092] The current backup set data refers to the backup set data stored on the target host at the current time.

[0093] 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 system of a host 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, the target host responds to the backup set data recovery instruction for the operating system of the source host, and 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 screening the second backup set data, during the screening process of 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 has an impact on the screening 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 the first backup set data and the current backup set data stored in the target host as candidate backup set data, multiple data sources are provided for the screening process of the second backup set data, rather than relying solely on a single backup source, which is beneficial to improving the flexibility of screening the backup set data.

[0097] In an exemplary embodiment, after obtaining the current network information, the above step S201 specifically includes the following contents: when the current network information is normal, obtaining 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.

[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 obtains the first backup set data directly from the storage server; when the current network information is abnormal, the target host needs to be physically connected to the storage device and obtain the first backup set data indirectly from the storage server.

[0099] Exemplarily, when current network information is normal, the target host establishes a network path between 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, the first backup set data is quickly obtained from the storage server associated with the source host by utilizing the convenience of the network and the efficiency of the storage server, which helps to reduce the data transmission time and thereby improve the efficiency of obtaining the backup set data.

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

[0102] The information characteristics of the current network information refer to characteristic information of the current network information, such as numerical values ​​corresponding to network delay and network bandwidth.

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

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

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

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

[0107] Among them, the preset probability refers to the pre-set probability size, such as 50%.

[0108] Exemplarily, the target host extracts information features of the current network information; then, the target host determines the importance of the information features, and selects information features whose importance is greater than a preset importance from the information features as key information features; then, the target host inputs the key information features into a feature extraction model, performs feature extraction processing on the key information features through the feature extraction model, and obtains a feature vector of the key information features; then, the target host inputs the feature vector into a trained network information detection model, and obtains an abnormality probability corresponding to the feature vector as the abnormality probability of the current network information; finally, when the abnormality probability is greater than the preset probability, the target host determines that the current network information is abnormal; when the abnormality 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, the current network information is predicted and processed through the trained network information detection model, so that the abnormal situation of the current network information can be quickly obtained, which is conducive to improving the efficiency of determining the abnormal situation of the current network information; and the entire process does not require human intervention, avoiding the defect of low efficiency in determining the abnormal situation of the current network information due to the time-consuming manual judgment method.

[0110] In an exemplary embodiment, Figure 4 As shown, another system recovery method is provided, which is applied to Figure 1 The target host in is used as an example to illustrate the process, including the following steps:

[0111] Step S401, obtaining current network information;

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

[0113] Step S403: Determine 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, the first backup set data is obtained 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, second backup set data corresponding to the backup set data recovery instruction is filtered out from the first backup set data.

[0117] Step S407, 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.

[0118] In the above-mentioned system recovery method, during the process of restoring the system, after determining that the current network information is abnormal, the backup set data recovery instruction is used to immediately determine the second backup set data for restoring the operating system of the source host from the first backup set data obtained according to the storage path information, thereby enabling the operating system of the source host to be quickly restored to normal operation, thereby improving the recovery efficiency of the system; moreover, the entire process does not require human intervention, thus avoiding the defect that the manual recovery method is prone to consume a lot of time and manpower, resulting in low system recovery efficiency, and further improving the recovery efficiency of the system.

[0119] In an exemplary embodiment, in order to more clearly illustrate the system recovery method provided by the embodiment of the present application, the system recovery method is specifically described below with a specific embodiment. Figure 5 As shown, the present application also provides a Linux operating system disaster recovery method. In the process of restoring the system, the current network information is first obtained. When the current network information is abnormal, the first backup set data is obtained 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, the second backup set data corresponding to the backup set data recovery instruction is screened out from the first backup set data. Finally, the operating system of the source host is restored according to the second backup set data. Specifically, it includes the following contents:

[0120] This system consists of three parts: source host, backup server and storage server. Users log in to the backup server to back up the source host and store it in the storage server. When restoring, the operating system is restored through network / offline methods. The system architecture diagram is shown in the figure below. Figure 1 shown.

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

[0122] After the backup is complete, you can restore the operating system in two ways: network or local, according to specific needs:

[0123] 1. Network recovery: Start the boot program on the target machine, log in to the backup server and list all backup sets. Select the backup set to be restored, configure the network, disk and other information, and then restore the operating system through network transmission.

[0124] 2. Local recovery: When the network fails or the operating system needs to be restored in an offline environment, the target machine can be restored offline by physically connecting the storage device or copying and burning the backup set files of the specified storage structure to the storage medium, so that the target machine can scan these backup set files through the boot program. However, since the boot program has certain rules for scanning backup sets, the backup set files need to be stored according to the specified storage structure when they are copied.

[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 target host network is normal, you can directly restore by connecting to the backup server.

[0129] 4. If the target host cannot access the network or the network fails, 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 physically connect it to the storage device.

[0131] 6. Use the recovery boot program to scan and list the backup set data in the target host disk.
