Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer and operating system, in particular to an operating system restoration method, a restoration device and a computing device. BACKGROUND

[0002] A computer as a terminal device of an information system, there are usually a large number of file data on the operating system. In order to prevent the system file from being lost or modified accidentally, the operating system itself generally provides a backup and restoration function, or uses third-party software to realize system backup and system restoration.

[0003] System backup is usually performed automatically by the operating system according to the plan or started by the user, and the file stored after the system backup is completed is called a restoration point. Generally, when the system runs for a long time, there may be multiple restoration points in the computer, and when the system needs to be restored due to problems, the system will provide a list of restoration points, and then the user can select a restoration point in the list.

[0004] However, the above-mentioned system restoration point selection method has the following problems: before the user selects the restoration point, the user cannot directly know whether the restoration point has the same problem as the current system, and cannot determine whether the restoration point can solve the problem expected by the user. Once the system restoration is started after the restoration point is selected, a certain amount of time is required for system restoration, and only after the restoration is completed, the user can perform operation judgment. If it does not meet the user's restoration expectations, the user needs to select a new restoration point for system restoration. In this way, a large amount of time will be consumed, resulting in poor user experience.

[0005] In addition, some software or functions existing on the current operating system may not exist in the restoration point or may not run normally. At this time, the user is more expected to rely on the restoration point to repair the problems existing in the current system and avoid the impact of existing normal software and functions caused by the overlay restoration.

[0006] Therefore, an operating system restoration method is needed to solve the problems in the above technical solutions. SUMMARY

[0025] Exemplary embodiments of the present disclosure will be described below in greater detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0026] Figure 1 is a schematic block diagram of an example computing device 100.

[0027] As shown in Figure 1 In a basic configuration 102, the computing device 100 typically includes a system memory 106 and one or more processors 104. A memory bus 108 can be used for communicating between the processor 104 and the system memory 106.

[0028] Depending on the desired configuration, the processor 104 can be of any type, including but not limited to a microprocessor (μP), a microcontroller (μC), a digital signal processor (DSP), or any combination thereof. The processor 104 can include one or more levels of caching, such as a level one cache 110 and a level two cache 112, a processor core 114, and registers 116. The example processor core 114 can include an arithmetic logic unit (ALU), a floating point unit (FPU), a digital signal processing core (DSP Core), or any combination thereof. An example memory controller 118 can also be used with the processor 104, or in some implementations, the memory controller 118 can be an internal part of the processor 104.

[0029] Depending on the desired configuration, the system memory 106 can be of any type, including but not limited to volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.) or any combination thereof. The system memory 106 can include an operating system 120, one or more applications 122, and program data 124. In some embodiments, the applications 122 can be arranged to execute instructions from the operating system 120 using the program data 124 by the one or more processors 104.

[0030] The computing device 100 also includes storage 132, which can include removable storage 136 and non-removable storage 138.

[0031] The computing device 100 can also include a storage interface bus 134. The storage interface bus 134 enables communication between the storage devices 132 (e.g., removable storage 136 and non-removable storage 138) and the basic configuration 102 via the bus / interface controller 130. The operating system 120, the application programs 122, and the data 124 are likely stored on the removable storage 136 and / or the non-removable storage 138 during operation of the computing device 100 by a user. Such software components can be loaded into the system memory 106 via the storage interface bus 134, and executed by the one or more processors 104 as it is being loaded or is subsequently being executed.

[0032] The computing device 100 can also include a bus / interface bus 140 that facilitates communication from various interface devices (e.g., output devices 142, peripheral interfaces 144, and communication devices 146) to the basic configuration 102 via the bus / interface controller 130. Example output devices 142 include a graphics processing unit 148 and an audio processing unit 150, which can be configured to facilitate communication to various external devices such as a display or speakers via one or more A / V ports 152. Example peripheral interfaces 144 can include a serial interface controller 154 or a parallel interface controller 156, which can be configured to facilitate communication to various external devices such as input devices (e.g., keyboard, mouse, pen, voice input device, touch input device) or other peripheral devices (e.g., printer, scanner, etc.) via one or more I / O ports 158. An example

[0033] The network communication link can be one example of a communication media. Communication media can typically be embodied by computer readable instructions, data structures, program modules, and / or other data in a modulated data signal, such as a carrier wave or other transport mechanism, and can include any information delivery media. A "modulated data signal" can be a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media can include wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, radio frequency (RF), microwave, infrared (IR) and other wireless media. The term computer readable media as used herein can include both storage media and communication media.

[0034] The computing device 100 can be implemented as a personal computer including desktop and notebook configurations. Of course, the computing device 100 can also be implemented as part of a small form factor portable (or mobile) electronic device such as a cell phone, a digital camera, a personal digital assistant (PDA), a personal media player device, a wireless web browsing device, a personal headset, an application-specific device, or a hybrid device that can include any of the above functions. The computing device 100 can even be implemented as a server, such as a file server, a database server, an application server, and a web server, among others. Embodiments of the present application are not limited to any particular implementation of the computing device 100.

[0035] In an embodiment according to the present application, the computing device 100 is configured to perform the operating system restoration method 200 according to the present application. In this embodiment, the operating system 120 of the computing device 100 contains a plurality of program instructions for performing the operating system restoration method 200 according to the present application, which can instruct the processor to perform the operating system restoration method 200 according to the present application, so that the computing device 100 can perform the operating system restoration method 200 according to the present application to restore the operating system.

[0036] According to an embodiment of the present application, the operating system 120 is deployed with a restoration apparatus 300, which contains a plurality of program instructions for performing the operating system restoration method 200 according to the present application, so that the operating system restoration method 200 according to the present application can be performed in the restoration apparatus 300, so that the restoration apparatus 300 can perform the operating system restoration method according to the present application to restore the operating system, and restore the operating system to the original state and make it run normally.

[0037] Figure 2 A flowchart of the operating system restoration method 200 according to an embodiment of the present application is shown. The operating system restoration method 200 can be performed in the operating system of a computing device (such as the aforementioned computing device 100). The operating system can be implemented as a Linux operating system, a Windows operating system, etc., and it should be noted that the present application is not limited to the specific type of operating system.

[0038] It should be noted that before the operating system restoration method 200 is performed, one or more restoration points can be created during the operation of the operating system. Specifically, the operating system can detect in real time whether the system files (such as some key files of the system) have changed, and when it is detected that the system files have changed, the system can be backed up by copying and storing the changed system files. And based on the backed up changed system files, the corresponding restoration points are created. In this way, when the operating system cannot run normally due to system file damage later, the operating system can be restored based on the pre-created restoration points.

[0039] Figure 2 As shown, the system restoration method 200 starts from step S210.

[0040] In step S210, the files of one or more restoration points are released into one or more predetermined directories. Wherein, each restoration point corresponds to a predetermined directory respectively.

[0041] Here, before performing step S210, one or more restoration points can be selected from the previously created restoration points, and then for each selected restoration point, a corresponding directory is specified as the predetermined directory for releasing the files of the restoration point, so that each restoration point releases files based on different paths. In this way, each selected restoration point corresponds to a predetermined directory respectively. For example, the predetermined directory corresponding to the restoration point 1 is IMG1_PATH, the predetermined directory corresponding to the restoration point 2 is IMG2_PATH, and the predetermined directory corresponding to the restoration point n is IMGn_PATH.

[0042] In this way, after performing step S210, each predetermined directory contains the files released by the corresponding restoration point.

[0043] It should be noted that one or more containers are also deployed on the operating system of the computing device, each container corresponding to a restoration point, and each container is used to run the corresponding restoration point. Here, the container is an independent virtual operating system running on the operating system, with an independently isolated running environment.

[0044] Subsequently, in step S220, one or more containers corresponding to one or more restoration points are run on the operating system. Wherein, each restoration point corresponds to a container respectively. Further, the files released by each restoration point in the predetermined directory are mounted to form the root file system of the container corresponding to the restoration point (i.e., the predetermined directory released by the restoration point is taken as the root directory of the corresponding container), so that each container can execute the files released by the corresponding restoration point based on the root file system of the container. It should be pointed out that by running each container to run the corresponding restoration point, it can be detected whether the files of the restoration point can meet the predetermined conditions for restoring the operating system.

[0045] Subsequently, in step S230, the execution results of each container are determined, and the target restoration point that can successfully restore the operating system is determined according to the execution results of each container.

[0046] It should be noted that the files released by the target restoration point are the files that meet the expected conditions and can successfully restore the operating system, and the operating system can be successfully restored based on the files released by the target restoration point.

[0047] According to one embodiment, when determining the target restore point according to the execution result of each container, it is determined whether the execution result of each container meets a predetermined condition, and if the execution result of the container on the file released by the restore point meets the predetermined condition, the restore point corresponding to the container is determined as the target restore point which can smoothly restore the operating system.

[0048] In one implementation, when determining whether the execution result of each container meets a predetermined condition, it is determined whether the container can normally execute the file of the restore point and whether the container can normally start after executing the file released by the restore point, and if the container can normally start, it is determined that the execution result of the container meets the predetermined condition, and the restore point corresponding to the container is determined as the target restore point. Conversely, if the container cannot normally start, it is determined that the execution result of the container does not meet the predetermined condition. In addition, if the file of the restore point cannot be executed in the container, it is also determined that the execution result of the container does not meet the predetermined condition, and the restore point cannot be used as the target restore point for restoring the operating system.

[0049] In addition, in other embodiments, it can also be determined whether the execution result of the container meets the predetermined condition according to the operation experience of the user to determine whether the restore point running through the container can be used as the target restore point.

[0050] After the target restore point is determined, the container running the target restore point can be exited, and the file released by the target restore point in the predetermined directory can be retained, so as to restore the operating system based on the file released by the target restore point.

[0051] As for the restore point which is not determined as the target restore point, the file released by the restore point in the predetermined directory can be deleted. Alternatively, after it is determined that the execution result of the container does not meet the predetermined condition, it is indicated that the restore point cannot be used for restoring the operating system, and in this case, the file released by the restore point corresponding to the container can be deleted.

[0052] It can be understood that after it is determined whether the execution result of each container meets the predetermined condition, one or more target restore points can be finally obtained. If the execution result of each container does not meet the predetermined condition, one or more restore points can be reselected, and steps S210-S230 are executed based on the reselected one or more restore points. Until one or more target restore points are finally obtained.

[0053] Finally, in step S240, the operating system is restored based on the file released by the target restore point, so that the operating system returns to the original state. Specifically, all the files released by the target restore point in the predetermined directory are used to overwrite, restore, etc. the corresponding files in the current system, so that the operating system returns to the original normal running state, and the repair of the operating system is realized.

[0054] Thus, according to the technical solution of the present application, when the operating system cannot normally run due to system file damage during running, the files of one or more restore points are executed by one or more containers respectively, the target restore point meeting the expectation is determined according to the execution result of each container on the restore point, and the operating system is restored based on the target restore point, so that the operating system can be restored to the original state by executing a restore process once, thereby realizing the quick repair of the current problem of the operating system.

[0055] According to still another embodiment, when the target restore point is determined according to the execution result of each container, the optimal execution result can also be determined by comparing the execution results of one or more containers, and the restore point corresponding to the optimal execution result is determined as the target restore point. It should be understood that the optimal execution result is obtained by comparison, and the most suitable restore point meeting the current running condition of the operating system is screened from multiple restore points, so that the operating system is restored based on the restore point as the target restore point, thereby ensuring that the operating system is smoothly restored to the original normal running state.

[0056] In one embodiment, the structure of OverlayFS file system can be used to mount the files released by each restore point in the predetermined directory to form the root file system of the container in step S220. Thus, when the system is backed up before the operating system restore method 200 of the present application is executed, full backup or incremental backup can be flexibly selected.

[0057] It should be understood that full backup means that the key system files and directories are all copied and compressed for system backup. When the operating system is restored based on the restore point (full restore point) created based on full backup, all the files released by the full restore point in the predetermined directory are used to perform operations such as covering and restoring on the corresponding files in the current system.

[0058] Incremental backup is to select a certain restore point that has been created as a reference restore point, and only the system files and directories that are different from the reference restore point are backed up when the operating system is backed up, i.e., only the differential system files are copied and compressed. Thus, when the operating system is restored based on the restore point (incremental restore point) created based on incremental backup, the files of the reference restore point are first released in the predetermined directory, and then the files of the incremental restore point are released in the predetermined directory, and then all the files released by the reference restore point and the incremental restore point are used to perform operations such as covering and restoring on the corresponding files in the current system, so that the operating system is restored to the original normal running state, thereby realizing the repair of the operating system.

[0059] Figure 3A diagram of a restoring device 300 according to an embodiment of the present application is shown. The restoring device 300 resides in an operating system of a computing device (e.g., the aforementioned computing device 100) and is adapted to perform the operating system restoring method 200 of the present application.

[0060] The restoring device 300 includes, in sequence, a releasing unit 310, a running unit 320, a determining unit 330, and a restoring unit 340. The releasing unit 310 is adapted to release the files of one or more restore points into one or more predetermined directories, wherein each restore point corresponds to a predetermined directory. The running unit 320 is adapted to run one or more containers corresponding to the one or more restore points and mount the files released by each restore point to form a root file system of the container, so that each container executes the files released by the corresponding restore point based on the root file system. The determining unit 330 is adapted to determine the execution result of each container and determine a target restore point based on the execution result of each container. The restoring unit 340 is adapted to restore the operating system based on the files released by the target restore point.

[0061] It should be noted that the releasing unit 310 is used to perform the aforementioned step S210, the running unit 320 is used to perform the aforementioned step S220, the determining unit 330 is used to perform the aforementioned step S230, and the restoring unit 340 is used to perform the aforementioned step S240. Here, the specific execution logic of the releasing unit 310, the running unit 320, the determining unit 330, and the restoring unit 340 can be found in the aforementioned description of steps S210-S240 of the method 200, and will not be repeated here.

[0062] According to the operating system restoring scheme of the present application, when the operating system cannot normally run due to system file damage during operation, the restore points are run through containers to detect whether the restore points meet the predetermined conditions for restoring the operating system. Specifically, the files of one or more restore points are executed through one or more containers, a target restore point that meets the conditions is determined based on the execution result of each container on the restore points, and the operating system is restored based on the target restore point. It should be noted that the present application restores the operating system based on the target restore point, which not only avoids the influence of the cover restoration on normal software and functions, repairs the current problems of the operating system, and makes all software and functions of the operating system run normally. Moreover, the target restore point obtained based on the execution result of one or more containers running one or more restore points can smoothly restore the operating system, so that the operating system can be restored to the original state after one restoration process, thereby realizing fast and efficient repair of the current problems of the operating system, avoiding the repeated operation of reselecting a restore point to restore the operating system again in the prior art, and thus improving the restoration efficiency of the operating system and saving time.

1. An operating system restore method, comprising the following steps: Extract files from multiple restore points to multiple predefined directories, with each restore point corresponding to one predefined directory; Multiple containers corresponding to multiple restore points are run, and files released by each restore point in a corresponding predetermined directory are mounted to form the root file system of the container corresponding to the restore point. Each container then executes the release of files from the corresponding restore point based on this root file system. The container is an independent virtual operating system running on an operating system, with an independent and isolated running environment; The execution result of each container is determined, and it is judged whether the execution result of each container meets predetermined conditions. Judging whether the execution result of each container meets predetermined conditions includes: determining whether the container starts normally after executing the files released from the restore point; if so, the execution result of the container is determined to meet predetermined conditions; if the execution result of the container meets predetermined conditions, the restore point corresponding to the container is determined as the target restore point; and The operating system is restored based on the files released from the target restore point.

2. The method as described in claim 1, wherein, After determining the target restoration point, the following steps are also included: Exit the container corresponding to the target restore point, but retain the files released by the target restore point so that the operating system can be restored based on the files released by the target restore point.

3. The method as described in claim 1, wherein, Before extracting files from multiple restore points to multiple predefined directories, the following steps are included: Select multiple restore points and specify a corresponding predefined directory for each selected restore point.

4. The method according to any one of claims 1-3, wherein, Before extracting files from multiple restore points to multiple predefined directories, the following steps are also included: Multiple restore points are created during the operation of the operating system.

5. The method of claim 4, wherein, The steps to create multiple restore points include: The system detects whether system files have changed. If they have changed, the system files are stored and corresponding restore points are created based on the changed system files.

6. A restore device, residing in an operating system, comprising: The release unit is suitable for releasing files from multiple restore points to multiple predefined directories, where each restore point corresponds to a predefined directory; The running unit is suitable for running multiple containers. It mounts the files released by each restore point in the corresponding predetermined directory to the corresponding container to form the root file system of the container. This allows each container to execute the release of the corresponding restore point based on the root file system. The container is an independent virtual operating system running on an operating system and has an independent and isolated running environment. The determining unit is adapted to determine the execution result of each container, and to determine whether the execution result of each container meets predetermined conditions. Determining whether the execution result of each container meets predetermined conditions includes: determining whether the container starts normally after executing the files released from the restore point; if so, determining that the execution result of the container meets predetermined conditions; if the execution result of the container meets predetermined conditions, determining the restore point corresponding to the container as the target restore point; and... The restoration unit is adapted to restore the operating system based on the files released from the target restore point.

7. A computing device, comprising: At least one processor; as well as A memory storing program instructions, wherein the program instructions are configured to be executed by the at least one processor, the program instructions including instructions for performing the method as described in any one of claims 1-5.

8. A readable storage medium storing program instructions that, when read and executed by a computing device, cause the computing device to perform the method as described in any one of claims 1-5.
