Description
Technical Field

Background
As is well known, in the process of using a mobile phone or a computer, an operating system is often required to be upgraded to support the latest applications or obtain more functions, but the upgrading of the system itself may cause problems: for example, in the upgrading process, power failure occurs, which causes damage to important files or data due to incomplete storage, and may also cause a certain accident due to a special software and hardware environment in the upgrading process, which causes a certain damage to the system. In short, neither computer system software nor hardware can guarantee one hundred percent stability.
Therefore, before the system upgrade, it is desirable to save the operating system that can currently run normally, so that after the system upgrade fails, the operating system can smoothly return to the version of the operating system before the upgrade. At present, in a Linux system, two ways are widely applied, one way is that tar is used for compressing a system file to be backed up, a user enters root authority, and directory files related to root files are compressed by using a tar command to complete backup, but the premise is that the user needs to enter the root authority, if the user performs irreversible operation under the root authority, an unrecoverable error of the system file is easily caused, the safety of the system cannot be guaranteed, and certain Linux command operation foundation is also needed for realizing switching by using the tar, so that the Linux system is not friendly to users who do not use Linux, after the user has certain Linux foundation, the user also needs to pay attention to the processing of a series of switching actions such as root file directories and root file authorities, and meanwhile, the tar is very time-consuming to compress the file. Another system backup method is that a root file is backed up by using a dd command, the name of a source hard disk device mounted by the root file needs to be known, and a spare hard disk not smaller than the size of the source hard disk is reserved, which also requires that a user has root authority, requires that the user has a certain Linux file and device management basis, and also causes a time-consuming aggravation phenomenon when a hard disk with a large dd backup size is used, so that the experience of the user is not friendly without knowing the dd command.
Therefore, a system backup and restore mechanism with simple operation and user friendliness is needed to improve the user experience.

FIG. 2 shows a flow diagram of a system management method 200 according to one embodiment of the invention. The method 200 is suitable for execution in a computing device, such as the computing device shown in fig. 1. Method 200 shows a schematic diagram of an operating system installation process. As shown in FIG. 2, the method 200 begins with creating a root partition and a backup partition at step S210. The root partition and the backup partition have the same file system type and hard disk space, and a configuration file is generated at the same time, wherein identifiers of the root partition and the backup partition are recorded in the configuration file, for example, an a partition and a B partition are created, wherein the a partition is marked as the root partition, and the B partition is marked as the backup partition.
Step S220 is then entered, and an operating system (e.g., Linux system) is installed in the created root partition, i.e., all system files generated during the system installation process are stored in the root partition (e.g., partition a in the above-described embodiment).
In step S230, copying the system files in the root partition to the backup partition, where kernel files are also needed to be backed up, the kernel files are in the/boot partition, a backup subdirectory is first created in the current/boot directory, and the backed-up kernel files and initrd files are stored in the backup subdirectory. In other words, the system files and kernel are backed up when the system is first successfully installed in the root partition.
While the operating system is in use, a user may upgrade and update the operating system according to an upgrade message pushed by the system, fig. 3 shows a flowchart of a system management method 300 according to an embodiment of the present invention, which is suitable for being executed in a computing device (e.g., the computing device shown in fig. 1), as shown in fig. 3, the method 300 starts with step S310, in which a system-pushed upgrade/update notification message is received when the operating system has a new version.
In this embodiment, before system upgrade, a user is asked whether to backup a current operating system, where the current operating system stores an application program and system configuration that the user needs to install and the system configuration is performed, when the user selects to backup the current operating system, step S320 is performed, in step S320, a system file in a current root partition is backed up, a current entire root partition file may be directly backed up to a current backup partition, the backup may also be completed according to a difference file between the root partition and the backup partition, a kernel file in a/boot partition is backed up at the same time, whether a backup subdirectory exists in the current/boot partition is detected, and if not, a backup subdirectory is created, the backed-up kernel file and initrd file are stored, initrd (initialization memory image) is a compressed small root directory, and the directory includes a driver module, a port, and a system configuration that are necessary in a system startup phase, The system file and the kernel can be backed up to form a backup node, and a user can back up a plurality of backup nodes corresponding to different states of the operating system.
And step S330, upgrading the system file of the current root partition, namely upgrading the system file in the current root partition according to the system upgrading notification to finish the upgrading of the operating system.
FIG. 4 illustrates a flow diagram of a method 400 of system management, the method 400 being suitable for execution in a computing device (such as the computing device shown in FIG. 1) having an operating system launcher, according to one embodiment of the present invention.
As shown in fig. 4, the method 400 starts in step S410, the operating system of the computing device is booted, and the operating system boot item is presented to the user after the operating system boot item is loaded, where the boot item includes "normal boot" and "recovery boot". When the user selects the conventional startup, step S430 is entered, and the configuration of the boot loader does not need to be modified, at this time, the kernel startup parameter of the first startup item is the UUID of the root partition, and the operating system is started directly from the current root partition.
When the user selects the restore boot entry, the process proceeds to step S440, and the backup partition is mounted to the root directory as the root partition according to the system boot entry selected by the user.
According to one embodiment of the invention, the Linux system manages data and hardware resources in a computer in the form of files, and various files are organized like a tree into a "directory tree", the root of the tree being the "root directory", and the symbol being "/". The hard disk partition is a part of the hard disk divided into a plurality of partitions, the hard disk partition is formatted with a file system and can be mounted to a directory tree, the file system is a method and a data structure used by an operating system for defining files on the partitions, namely a method for organizing the files on a storage device, the mounting is that a directory is used as an entry point (similarly, an existing directory is selected as a proxy), the partitioned file system is placed under the directory, the content of the file system can be read and written by entering the directory, and the directory of the entry point is called as a mounting point similarly that the whole file system forms a folder of the directory tree.
In this embodiment, a multi-operating system boot program (GRUB) is invoked to modify the configuration of the boot loader, the configuration file generation process of the GRUB is executed again, the kernel boot parameters of the operating system are associated with the backup partition, the previous backup partition is mounted to the root directory, and the root directory is used as a root partition boot operating system, for example: and B is a backup partition, the kernel starting parameter of the first starting item is modified into the UUID of the current backup partition B, and the system is started by taking the partition B as a root partition when being started. Meanwhile, the kernel file and initrd file in the backup directory under the/boot directory need to be copied into the/boot.
When the system is started, the boot loader reads the initrd file into the memory, and then transmits the initial address and the size of the file in the memory to the kernel. The kernel decompresses the initrd file in the process of starting initialization, mounts the decompressed initrd as a root directory, executes an initialization script in the root directory, and reads kernel startup parameters, wherein the script comprises a root parameter (namely UUID of a partition), the root parameter indicates which partition is a root partition, finds and mounts the root partition, and switches the root partition into a new root directory, and the root directory is the root directory which is finally seen after the system is started. In the above embodiment, the root parameter is the UUID of the partition B, and the partition B is used as the root partition to start.
And then, the step S450 is carried out, the system files of the current root partition are backed up to the current backup partition, and the restoration starting item in the system starting guide item is deleted. That is, files in the current root partition (the original backup partition, the partition B in the above embodiment) are backed up to the current backup partition (the original root partition, the partition a in the above embodiment), and meanwhile, currently used kernel files and initrd files are backed up to the backup subdirectory in the boot. The system files in the current root partition and the backup partition are completely the same, and so-called restore startup is not needed, so in this step, the restore startup item in the system startup boot item after the operating system launcher loads is also deleted.
According to one embodiment of the invention, a user can create a plurality of backup nodes in the whole operating system using process, and the backup nodes for system recovery are realized by adding different system starting guide items.
