Description

System restore method and apparatus, computing device, and readable storage medium

Technical Field

The present invention relates to the field of system backup and restore technologies, and in particular, to a system restore method and apparatus, a computing device, and a readable storage medium.

Background

With the rapid development of computer software technology, more and more computer software is developed for users. Most software provides a configuration interface to facilitate the user to implement the desired functionality by modifying the configuration, either to make its application as wide as possible, or to meet the user's differentiated needs.

Meanwhile, in order to shorten the software development process, a software developer generally divides functions implemented by the software into smaller granularity, so that the following situations occur: when a user is to perform a function, it is often necessary to install and deploy a plurality of software packages and configure the software packages so that the software packages cooperate with each other to perform the desired function. Because of the large number of software packages, the software packages need to be matched with each other, so that the configuration and the deployment become a time-consuming and labor-consuming work. Once the configuration data is destroyed, modified, or inadvertently deleted or uninstalled, the entire software system is destroyed and cannot continue to operate. At this time, it often takes more time to configure and debug the recovery system.

For this situation, in the current computer operating system, there are mainly two ways to implement system restoration: firstly, the operating system itself provides a backup and restore function; and secondly, realizing 'system backup' and 'system restoration' by means of third-party software. These "system backup" and "system restore" are roughly classified into the following categories according to the implementation principle:

1. when the system works normally, the data needing to be backed up is selected to be copied and backed up, and then the 'covered' type recovery of the hard disk data is carried out when the subsequent needs are carried out, so that the 'system restoration' is achieved. This method may be referred to as "hard disk data replication".

2. When the system is subjected to major change (such as software upgrading and software unloading), the system software data is backed up, or the system software data is periodically backed up to create a return point, and the original disk data is covered by the return point when the system is required subsequently, so that the purpose of system restoration is achieved.

However, both of these methods have the following problems:

1. when the system is backed up, the operation time of the backup operation is longer because of more backup data. At this time, the following problems may be caused: a. if the user is not allowed to perform system configuration, software installation-related operations during "backup", it may result in the user not fully operating the computer for a long period of time. b. If the user is allowed to perform system configuration, software installation-related operations during "backup", a situation may occur in which the user backup data is inconsistent. Such as: a certain software package of a user contains 1000 files, which may change during backup, so that only part of the files therein are backed up, resulting in an invalid or incomplete "restore point".

2. Because of the more data backed up, the more memory space is occupied by the "restore point", which creates a memory burden for the user. Meanwhile, the occupied storage space is more, the creation frequency of the 'restore point' is limited, and the 'restore point' cannot be created with smaller granularity in the time dimension for a system with more modification requirements.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to 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 disclosure to those skilled in the art.

First, two basic concepts used herein will be briefly described: system backup and system restore. The system backup refers to storing software data running on a system in a certain format, and the data stored by the system backup is generally called as an "restore point". System restore refers to "restoring" a portion of the data of the system in accordance with or with reference to a "restore point" such that all or a portion of the software functionality of the system is restored to the state at the time the "restore point" was generated.

Drawbacks of the prior art backup restoration method mentioned in the background section include: the backup operation requires longer running time and occupies more storage space at the restore point. For example, the cloning software ghost can backup binary data of the partition of the disk, and can also restore the partition data by using the backup file. The cloning software can back up and cover the whole disk data, and can restore the data file of the user to the creation time of the restore point during the restore process, but the modification of the data file by the user is destroyed within a period of time from the creation time of the restore point to the restore process of the system. The technical problems mentioned in the background art may also be caused if the system's own backup-restore function is used, such as full-disk backup (full-disk backup refers to backup of all data of the current system), and system backup (system backup refers to backup of only software packages and related files provided by the operating system itself).

According to the technical scheme of the invention, a lightweight system backup and restore scheme is provided. The scheme is realized mainly by utilizing the following characteristics of the current operating system:

most software packages of operating systems currently provide network sources or software installation images. When operating system changes, it is usually due to: the user installs the software, uninstalls the software, or modifies the configuration file of the software package. And a, for a specific operating system, a software package can be uniquely determined through a software name and a version number. Other files in the software package than the configuration files may be modified by the user are not optionally modifiable, including executable programs provided by the software package, or even if modified, do not require a backup or record, such as help files provided by the software package. The configuration file contains information required for successfully running the software package, which is not hard-coded in the program, but is user-configurable, typically in the form of a plain text file. b. For a certain operating system, the configuration items of the software package have a storage path with a relatively uniform specification. For a linux operating system, for example, the/etc directory is typically the storage path for the configuration files of the operating system itself and the storage path for the configuration files of the software package.

Based on the above, it is possible to backup only the following contents when performing system backup: a list of software packages (containing the names and versions of the software packages) that the system is currently installed, and the configuration files for all software packages. This results in as little data to be stored in the "restore point" as possible, thus resulting in less memory space being occupied by the "restore point", less runtime being required to create the "restore point", and less computer resources being consumed.

In addition, for some systems, at boot-up, boot is first performed into a memory file system that holds the underlying commands and/or applications and their dependencies. The primary starting process comprises the steps of starting and loading the memory file system by the kernel, then creating and mounting the disk file system in the memory file system, and then guiding the disk file system into the disk system. Based on this, the virtual file system may be modified to ensure that the system is restored at startup according to a specified "restore point" and then rebooted into the disk system. Based on this, a "system restore" can be performed in the virtual file system, namely: whether or not the system in the disk can be started up normally, the system can be restored and repaired by the system restoration. It should be understood that the present invention is not limited by this implementation, and that a specific implementation may be determined by one skilled in the art according to a specific system environment, and a system development process.

According to an embodiment of the invention, a system restoration method is provided. Fig. 1 shows a schematic flow chart of an example of the system restore method. As shown in FIG. 1, the system restore method includes steps 110-160. The steps are described in detail below.

In step 110, the installed software package is queried and the name of the installed software package is stored as a software package installation list. The query method may be, for example: for systems such as linux systems, debian\ubuntu\deepin, the inquiry can be carried out by adopting a command apt list-insiled; the system such as centos, rhel, euler can be queried using the command rpm-qa. The resulting package installation list may exist in the form of a document such as WORD, EXCEL, but is not limited thereto as long as it can be stored as a list of package names in local/remote storage.

In step 120, the software package configuration file of the already installed software package is looked up and saved.

In step 130, an restore point is created from the above-described package installation list and package configuration file, the restore point being a data set including the package installation list and package configuration file. Optionally, to reduce the disk space occupied by the restore point, the files contained in the restore point may be compressed.

In step 140, the software package installation list is read from the restore point, which includes the software package installation list and the software package configuration file.

In step 150, the software package is downloaded and installed according to the read software package installation list. The download may be from a "source". "Source" refers to an application installation repository, which may be an online repository, accessed over a network to download and install software packages; or may be a file stored locally on the computer system. Before the downloading is performed, if the user determines that it is necessary, the software package set installed in the current disk may be deleted first, specifically, some key directories of the system may be deleted first, for example, for the linux system, directories such as/usr,/etc. may be deleted.

In step 160, the software package configuration file is read from the restore point, and the system restore is performed using the software package configuration file. The system restore here refers to: the default configuration is overridden with the backed up software package configuration file to restore the software function to the state at the time of "restore point" generation. "default configuration" refers to the configuration being in a default state when the package has just been downloaded and installed in step 150. Typically, the backed up package configuration file is the result of long-term debugging and use based on the user's needs for functionality.

So far, the system is restored and executed. The system may then be booted to disk so that the restored system begins to operate. In the whole restoration process, only the software package installed by the user is reinstalled and the configuration file is restored, so that the data file of the user is not modified or destroyed.

The backup operation may be performed periodically, and the time point and the interval time of specific execution are not limited. In the case of periodic execution, a plurality of restore points may be stored in correspondence with the time at the time of generation. When the system is restored, the system state at any time can be selected and restored according to the requirement.

The system restore method described above can be used to restore additional computer systems (computer systems that do not generate restore points) to achieve "cloning" of different computer system software systems. The "cloning" of software systems between different computers applies, for example, to the following cases: in a clustered system, for example, an operator needs to manage up to 1000 computers and expects the states of these computers to be identical. At this time, only one computer needs to be debugged to obtain the expected configuration and backup, and then the backup is adopted to restore the system on other 999 computers to obtain the expected result.

Variations on the above system restore method are also possible. Specifically, a "reference" restore point may be backed up first, and based on this backup scheme, subsequent restore points may be "incremental" backups based on the "reference" restore point. When the system restoration is needed, the content of the expected restoration can be calculated according to the reference restoration point and the incremental restoration point, and then the system restoration is carried out. The reference restore point can be obtained by the following method: after the system is installed and subjected to basic debugging, the relatively stable system state after the debugging is backed up as a reference restore point. The manner in which the reference restore point is obtained may also be specified by those skilled in the art as desired.

Therefore, according to an embodiment of the present invention, there is also provided a system restoration method. Fig. 2 shows a schematic flow chart of an example of the system restore method. As shown in fig. 2, the method includes steps 210-230. The steps are described in detail below.

In step 210, a reference software package installation list is read from a reference restore point, an incremental software package installation list is read from an incremental restore point, and a software package installation list corresponding to the incremental restore point is obtained through calculation, wherein the reference restore point comprises the reference software package installation list and a reference configuration file, the incremental restore point comprises the incremental software package installation list and the incremental configuration file, the incremental software package installation list represents changes of the software package installation list corresponding to the incremental restore point relative to the reference software package installation list, and the incremental configuration file represents differences of the software package configuration file corresponding to the incremental restore point relative to the reference configuration file.

In step 220, the software package is downloaded and installed according to the software package installation list corresponding to the incremental restore point.

In step 230, the reference configuration file is read from the reference restore point, the incremental configuration file is read from the incremental restore point, the software package configuration file corresponding to the incremental restore point is obtained by calculation, and the system restore is performed using the software package configuration file corresponding to the incremental restore point.

The method shown in fig. 2 may also include a backup process. As shown in fig. 3, this backup process example may include the steps of: in step 310, comparing the changes of the current software package installation list relative to the reference software package installation list, and storing the changes as an incremental software package installation list; in step 320, the differences of the software package configuration files of the already installed software packages with respect to the reference configuration files are compared and stored as incremental configuration files; in step 330, an incremental restore point is created from the incremental package installation list and the incremental configuration file described above.

The reference restore point used in the backup process can be backed up in advance, and the backup process can also be used for backing up. That is, the backup process shown in fig. 3 may further include a reference point backup process: inquiring the software package installed at the reference time point, and storing the name of the software package installed as a reference software package installation list; searching a software package configuration file of the software package installed at the reference time point and storing the software package configuration file as a reference configuration file; and creating a restore point through the reference software package installation list and the reference configuration file. As described above, the reference point in time may be a relatively stable point in time after the system has been installed and has undergone a basic debug, or other provision made by those skilled in the art.

According to the technical scheme of the embodiment of the invention, a lightweight system backup and restore scheme is realized, the realization is simple, the backup speed is high, the running time is short, the occupied computing resource is less during running, and the memory space occupied by the restore point is less. And as described above, the restore point created by one computer can be applied to another computer for system restore, so that "software system cloning" between different calculations can be realized.

According to the embodiment of the invention, a system reduction device is also provided. Fig. 4 shows a schematic block diagram of an example of the system restore device 400. As shown in fig. 4, the system restore device 400 includes a backup module 410, a reading module 420, an installation module 430, and a restore module 440. Wherein, the reading module 420 is configured to read the software package installation list from an restore point, where the restore point includes the software package installation list and the software package configuration file. The installation module 430 is configured to download and install the software package according to the read software package installation list. The restore module 440 is configured to read the software package configuration file from the restore point and use the software package configuration file to perform system restore.

The backup module may include: the software package inquiring sub-module is used for inquiring the installed software package and storing the name of the installed software package as a software package installation list; the configuration file searching sub-module is used for searching the installed software package configuration file and storing the software package configuration file; and the creation sub-module is used for creating an restore point through the software package installation list and the software package configuration file. Optionally, the backup module may further include a compression sub-module, configured to compress a file included in the restore point, so as to reduce disk space occupied by the restore point.

According to an embodiment of the present invention, there is provided another system restoration device including a reading module, an installation module, and a restoration module. The reading module is used for reading a reference software package installation list from a reference restoration point, reading an incremental software package installation list from an incremental restoration point, and calculating to obtain a software package installation list corresponding to the incremental restoration point, wherein the reference restoration point comprises the reference software package installation list and a reference configuration file, the incremental restoration point comprises the incremental software package installation list and the incremental configuration file, the incremental software package installation list represents the change of the software package installation list corresponding to the incremental restoration point relative to the reference software package installation list, and the incremental configuration file represents the difference of the software package configuration file corresponding to the incremental restoration point relative to the reference configuration file. The installation module is used for downloading and installing the software package according to the software package installation list corresponding to the incremental restore point. The restoring module is used for reading the reference configuration file from the reference restoring point, reading the incremental configuration file from the incremental restoring point, calculating to obtain the software package configuration file corresponding to the incremental restoring point, and restoring the system by using the software package configuration file corresponding to the incremental restoring point.

The system restore device may include a backup module, which may include: the reference restore point backup sub-module is used for backing up a reference restore point, and the reference restore point comprises a reference software package installation list and a reference configuration file. And the incremental software package installation list backup sub-module is used for comparing the change of the installed software package list relative to the reference software package installation list and storing the change as the incremental software package installation list. The incremental configuration file backup sub-module is used for comparing the difference between the software package configuration file of the installed software package and the reference configuration file and storing the difference as the incremental configuration file. The incremental restore point creation module is configured to create an incremental restore point through the incremental software package installation list and the incremental configuration file.
