How to backup and restore windows operating system

Abstract

The present invention discloses a method for backing up and restoring a Windows operating system. The method comprises: firstly, adding a Chinese font into a FreeBSD kernel, and simultaneously modifying a font acquisition function of the kernel, so as to implement kernel-level Chinese display support; secondly, combining a GRUB2 boot manager that simultaneously supports BIOS (Basic Input / Output System) and UEFI specification, the FreeBSD kernel that is modified into a Chinese way, a user space program that implements backup and restoration functions, and a storage space that stores a backup file, so as to form a backup and restoration system; thirdly, by means of one of three modes of a local hard disk, an external memory and a PXE network, starting the backup and restoration system, and separately mounting a ZFS or NFS file system according to different starting modes; fourthly, by means of a sequence number module, calculating a "host sequence number" and a "hard disk sequence number" of a local computer, and using the sequence number as a unique sequence number, and checking whether a corresponding backup file exists; and finally, entering a "backup" or " restoration" process according to selection of a user.

Description

technical field [0001] The invention relates to the backup and restoration technology of the Windows operating system, in particular to a method for backing up and restoring the Windows operating system by utilizing the FreeBSD technology. Background technique [0002] (1) Backup and restore of Windows operating system [0003] There are two main backup and restore technologies of the common Windows operating system: one is the "system restore" technology that comes with the Windows operating system, and the other is various "one-key Ghost" technologies based on Ghost. [0004] The "system restore" technology that comes with Windows has serious inherent defects. Because the premise of using "System Restore" is to be able to start the Windows system normally, once the Windows system itself cannot start normally (for example, some key files are damaged), this technology will also fail. [0005] All "one-click Ghost" are essentially composed of the following three parts: ...

AI Technical Summary

Problems solved by technology

Although in practice, all kinds of "one-click Ghost" will add hidden attributes to these files, but it still cannot fundamentally eliminate this risk

Fundamentally speaking, all backup and restoration technologies based on Windows or DOS systems have this shortcoming.

[0011] 2. Data compression technology is not ideal

At the same time, since Ghost only uses single-thread compression, it cannot make full use of the parallel computing capabilities of today's multi-core CPUs.

[0012] 3. Low degree of intelligence, not suitable for use in large-scale scenarios

Due to the huge amount, it is very error-prone to rely on manual matching, so the lack of an automated matching mechanism greatly increases the workload and error rate of maintenance personnel

[0013] 4. Does not support the latest UEFI technical specifications

As the BIOS is gradually being replaced by UEFI, and many of the latest motherboards are no longer compatible with the traditional BIOS mode, the adaptability of various "one-key Ghost" is constantly decreasing

[0014] 5. Ghost’s native English interface is not friendly to Chinese users

However, in order to display Chinese, not only need to add Chinese plug-in programs, but also need to add many function libraries and Chinese fonts required by the plug-in programs to run.

This obviously increases the complexity of the system

[0024] 2. It may conflict with other user space programs, and the compatibility is not good

Because the Chinese plug-in program needs to occupy the frame buffer device, it will conflict with other programs (such as w3m) that also use the frame buffer device, resulting in compatibility failures
