Description

Operating system restoration method, restoration device and computing equipment

Technical Field

The present invention relates to the field of computer and operating system technologies, and in particular, to an operating system restoring method, an operating system restoring apparatus, and a computing device.

Background

A computer is used as a terminal device of an information system, and a large amount of file data often exists on an operating system of the computer. To prevent accidental loss or modification of system files, the operating system itself typically provides backup-restore functionality, or third-party software is used to implement system backup and system restore.

The system backup is usually executed automatically according to a plan or started by a user, and a file stored after the system backup is executed is called a restore point. Generally, when the system runs for a long time, a plurality of restoring points may exist in the computer, and when the system has a problem and needs to be restored, the system provides a restoring point list, and then the user can select the restoring point in the restoring point list.

However, the reduction point selection method for the above system reduction has the following problems: before selecting a restore point, a user cannot directly know whether the restore point has the same problem as that of the current system or determine whether the restore point can solve the problem that the user desires to solve. Once the system is restored by selecting the restoration point, it takes a certain time to restore the system, and only after the restoration is completed, the user can perform operation judgment. If the system is not in accordance with the user's restoration expectation, the user also needs to reselect the restoration point for system restoration. Thus, it will inevitably take a lot of time, resulting in poor user experience.

In addition, some software or functions present on the current operating system may not be present or may not function properly in the restore point. At this time, the user more expects to rely on the restore point to repair the problems existing in the current system, and the influence on the existing normal software and functions caused by the overlay restoration is avoided.

Therefore, an operating system recovery method is needed to solve the problems in the above technical solutions.

The example processor core 114 may include an Arithmetic Logic Unit (ALU), a Floating Point Unit (FPU), a digital signal processing core (DSP core), or any combination thereof. The example memory controller 118 may be used with the processor 104, or in some implementations the memory controller 118 may be an internal part of the processor 104.

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

Computing device 100 also includes a storage device 132, storage device 132 including removable storage 136 and non-removable storage 138.

An example communication device 146 may include a network controller 160, which may be arranged to facilitate communications with one or more other computing devices 162 over a network communication link via one or more communication ports 164.

A network communication link may be one example of a communication medium. Communication media may typically be embodied by computer readable instructions, data structures, program modules, and may include any information delivery media, such as carrier waves or other transport mechanisms, in a modulated data signal. A "modulated data signal" may be a signal that has one or more of its data set or its changes made in a manner that encodes information in the signal. By way of non-limiting example, communication media may include wired media such as a wired network or private-wired network, and various wireless media such as acoustic, Radio Frequency (RF), microwave, Infrared (IR), or other wireless media. The term computer readable media as used herein may include both storage media and communication media.

And may even be implemented as a server, such as a file server, a database server, an application server, a WEB server, and so forth. The embodiments of the present invention are not limited thereto.

In an embodiment in accordance with the invention, the computing device 100 is configured to perform an operating system restore method 200 in accordance with the invention. The operating system 120 of the computing device 100 includes a plurality of program instructions for executing the operating system restoring method 200 of the present invention, and these program instructions may instruct the processor to execute the operating system restoring method 200 of the present invention, so that the computing device 100 realizes restoring the operating system by executing the operating system restoring method 200 of the present invention.

According to an embodiment of the present invention, the restoring apparatus 300 is disposed in the operating system 120, and the restoring apparatus 300 includes a plurality of program instructions for executing the operating system restoring method 200 of the present invention, so that the operating system restoring method 200 of the present invention can be executed in the restoring apparatus 300, so that the restoring apparatus 300 restores the operating system by executing the operating system restoring method of the present invention, so that the operating system is restored to the original state and runs normally.

FIG. 2 shows a flow diagram of a method 200 for operating system restore, according to one embodiment of the invention. Operating system restore method 200 may be performed in an operating system of a computing device (e.g., computing device 100 described above). The operating system may be implemented, for example, as a Linux operating system, a Windows operating system, etc., and it should be noted that the present invention is not limited to a specific kind of operating system.

It should be noted that one or more restore points may be created during the operation of the operating system prior to performing the system restore method 200. Specifically, the operating system may detect whether a system file (e.g., some key files of the system) changes in real time, and when a change in the system file is detected, the system may be backed up by copying and storing the changed system file. And, a corresponding restore point is created based on the backed-up changed system file. In this way, the operating system can be restored based on the pre-created restoration point subsequently when the operating system cannot normally run due to the damage of the system file.

As shown in fig. 2, the system restoring method 200 starts in step S210.

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

Here, before performing step S210, one or more restore points may be selected from the previously created restore points, and then, a corresponding one of directories is respectively designated for each of the selected restore points as a predetermined directory for the restore point release file, so that each of the restore points releases the file based on a different path. Thus, each of the selected restore points corresponds to a respective predetermined directory. For example, the predetermined directory corresponding to the restore point 1 is IMG1_ PATH, and the predetermined directory corresponding to the restore point 2 is IMG2_ PATH … …, and the predetermined directory corresponding to the restore point n is IMGn _ PATH.

Thus, after step S210 is executed, each predetermined directory includes the file released by the corresponding restore point.

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

Subsequently, in step S220, one or more containers corresponding to the one or more restore points are run on the operating system. Wherein each reduction point corresponds to a container. Further, each restore point releases the files under the predetermined directory to form a root file system of the container corresponding to the restore point (i.e., the predetermined directory released by the restore point is taken as the root directory of the corresponding container), so that the corresponding file released by the restore point can be executed by each container based on the root file system of the container. It should be noted that by running the corresponding restore point with each container, it can be detected whether the file of the restore point can satisfy a predetermined condition for restoring the operating system.

Subsequently, in step S230, the execution result of each container is determined, and a target restore point capable of successfully restoring the operating system is determined according to the execution result of each container.

It should be noted that the file released by the target restore point is a file that satisfies expectations and can smoothly restore the operating system, and the file released by the target restore point can smoothly restore the operating system.

According to one embodiment, when the target restoring point is determined according to the execution result of each container, by judging whether the execution result of each container meets a preset condition, if the execution result of the container on the file released by the restoring point meets the preset condition, the restoring point corresponding to the container is determined as the target restoring point capable of smoothly restoring the operating system.

In one implementation, when determining whether the execution result of each container meets a predetermined condition, it may be determined whether the container can normally execute the file of the restore point, and determine whether the container can be normally started after executing the file released by the restore point, and if the container can be normally started, determine that the execution result of the container meets the predetermined condition, and take the restore point corresponding to the container as the target restore point. Otherwise, if the container can not be started normally, the execution result of the container is determined to be not in accordance with the preset condition. In addition, if the file of the restore point cannot be executed in the container, it may also be determined that the execution result of the container does not meet a predetermined condition, and the restore point cannot be a target restore point for restoring the operating system.

In addition, in other embodiments, whether the execution result of the container meets a predetermined condition may also be determined according to the operation experience of the user, so as to determine whether the restore point operated by the container can be used as the target restore point.

After the target restore point is determined, the container running the target restore point may be exited, and the target restore point is reserved to release files under a predetermined directory, so as to restore the operating system based on the files released by the target restore point.

And for the restoration points which are not determined as the target restoration points, the files of which the restoration points are released under the preset directory can be deleted. Or, after determining that the execution result of the container does not meet the predetermined condition, it indicates that the restore point cannot be used for restoring the operating system, in which case the file released by the restore point corresponding to the container may be deleted.

It is understood that after determining whether the execution result of each container meets the predetermined condition, one or more target restore points may be finally obtained. If the execution result of each container does not meet the predetermined condition, one or more restoration points may be reselected, and steps S210 to S230 may be performed based on the reselected one or more restoration points. Until one or more target reduction points are finally available.

Finally, in step S240, the operating system is restored based on the file released by the target restoring point, so that the operating system is restored to the original state. Specifically, all files in a predetermined directory are released based on the target restore point to perform operations such as covering and restoring on corresponding files in the current system, so that the operating system is restored to the original normal running state, and the operating system is repaired.

Thus, according to the technical scheme of the invention, when the operating system cannot normally run due to system file damage in the running process, the files of one or more restoring points are respectively executed through one or more containers, the target restoring point which is in line with expectation is determined according to the execution result of each container on the restoring point, and the operating system is restored based on the target restoring point, so that the operating system can be restored to the original state by executing one restoring process, and the problem of the operating system which currently occurs can be quickly repaired.

According to still another embodiment, when the target reduction point is determined according to the execution result of each container, the optimal execution result may be determined by comparing the execution results of one or more containers, and the reduction point corresponding to the optimal execution result may be determined as the target reduction point. It should be understood that the optimal execution result is obtained through comparison, the most appropriate restoration point which meets the current operation condition of the operating system can be screened out from the plurality of restoration points, the restoration point is used as a target restoration point to restore the operating system, and the operating system can be ensured to be successfully restored to the original normal operation state.

In one embodiment, in step S220, the structure of the OverlayFS file system may be adopted to mount each restore point to release the file under the predetermined directory, forming the root file system of the container. In this way, when the system is backed up before the operating system restoring method 200 of the present invention is executed, a full backup or an incremental backup can be flexibly selected.

It should be understood that full backup is the copying and compression of all critical system files and directories to make a system backup. When the operating system is restored based on the restoring point (full restoring point) created by the full backup, all files under a predetermined directory are released based on the full restoring point to perform operations such as overwriting and restoring on the corresponding files in the current system.

The incremental backup is to select a certain restoring point which has already been created as a reference restoring point, and when the operating system is backed up, only the system files and directories which are different from the reference restoring point are backed up, that is, only the different system files are copied and compressed. In this way, when the operating system is restored based on the restoration point (incremental restoration point) created by the incremental backup, the file of the reference restoration point is released in the predetermined directory, the file of the incremental restoration point is released in the predetermined directory, and then the corresponding file in the current system is covered and restored based on all the files released by the reference restoration point and the incremental restoration point, so that the operating system is restored to the original normal operating state, and the restoration of the operating system is realized.

FIG. 3 shows a schematic view of a reducing apparatus 300 according to an embodiment of the invention. The restoring apparatus 300 resides in an operating system of a computing device (e.g., the aforementioned computing device 100), and is adapted to execute the operating system restoring method 200 of the present invention.

The reducing apparatus 300 includes a releasing unit 310, an operating unit 320, a determining unit 330, and a reducing unit 340, which are connected in sequence. The release unit 310 is adapted to release the file of one or more restore points into one or more predetermined directories, where each restore point corresponds to one predetermined directory. The execution unit 320 is adapted to execute one or more containers corresponding to one or more restore points and mount the file released by each restore point to form a root file system of the container, such that each container executes the corresponding file released by the restore point based on the root file system. The determination unit 330 is adapted to determine an execution result for each container, and to determine the target reduction point based on the execution result for each container. The restoring unit 340 is adapted to restore the operating system based on the file released by the target restoring point.

It should be noted that the releasing unit 310 is configured to execute the aforementioned step S210, the running unit 320 is configured to execute the aforementioned step S220, the determining unit 330 is configured to execute the aforementioned step S230, and the restoring unit 340 is configured to execute the aforementioned step S240. Here, for the specific execution logic of the releasing unit 310, the operating unit 320, the determining unit 330, and the restoring unit 340, reference is made to the description of steps S210 to S240 in the method 200, and details are not repeated here.

According to the operating system restoration scheme, when the operating system cannot normally run due to system file damage in the running process, the restoring point is run through the container, so that whether the restoring point meets the preset condition for restoring the operating system or not is detected. Specifically, files of one or more restore points are executed by one or more containers respectively, a target restore point meeting conditions 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. It should be noted that the present invention restores the operating system based on the target restoring point, which not only can avoid the influence of overlay restoring on normal software and functions, but also can repair the current problems of the operating system, so that all the software and functions of the operating system run normally. Moreover, the target reduction points obtained by screening can smoothly reduce the operating system according to the execution result of one or more reduction points operated by one or more containers, so that the operating system can be restored to the original state by executing a reduction process once, the current problems of the operating system can be quickly and efficiently repaired, the repeated operation of reselecting the reduction points to reduce the operating system again in the prior art is avoided, the reduction efficiency of the operating system is improved, and the time is saved.
