Abstract

The invention discloses an operating system mirror image storage and recovery method and an operating system mirror image storage and recovery device. The method comprises the following steps: abstracting the reserved address space of a non-volatile random-access memory into storage equipment through a drive program; formatting the storage equipment into an exchange partition through a formatting command; automatically mounting the exchange partition when a computer is started by modifying a mounting configuration file; setting the exchange partition as system mirror image recovery equipment by modifying a start-up configuration file, and storing and recovering an operating system mirror image through the exchange partition. By applying the technical scheme provided by the embodiment of the invention, the use of the non-volatile random-access memory-based storage equipment when the operating system mirror image is stored and recovered can be ensured; data can be retained permanently in the non-volatile random-access memory; the data are prevented from losing when a system is powered down; moreover, the operating system mirror image storage and recovery speed can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for saving and restoring an operating system image. Background technique [0002] In the computer, the operating system image is saved in time so that the operating system image can be restored when needed. [0003] At present, the storage in the computer mainly includes two types of storage: system memory and external storage. [0004] The common system memory is DRAM (Dynamic Random Access Memory, Dynamic Random Access Memory). DRAM has a very short storage time for data. If the storage unit is not refreshed, the data stored therein will be lost, and the computer will also be shut down to cause data loss. Therefore, the operating system image cannot be saved in the DRAM. [0005] External storage mainly includes mechanical disks, solid-state drives, and distributed storage devices. At present, operating system images are mostly stored on disks, but due ...
