Breakpoint restoration method and system based on heterogeneous hybrid memories

Abstract

The invention discloses a breakpoint restoration method based on heterogeneous hybrid memories. The method comprises following steps of booting and powering on; in a power on self-test process of booting for the non-first time, executing following steps of detecting whether a last time shutdown is illegal shutdown or not; detecting whether an operation system mirror backed up in advance is in a NVM (Nonvolatile Memory) or not if the last time shutdown is the illegal shutdown; copying the operation system mirror image to a DRAM (Dynamic Random Access Memory) if the operation system mirror is in the NVM; booting the operation system mirror image from the DRAM; booting the operation system mirror image from an external storage device if the operation system mirror is not in the NVM; and booting the operation system mirror image from the external storage device if the last time shutdown is not the illegal shutdown. According to the method, through utilization of the feature that the data in the NVM will not disappear when there is a power failure, the operation program state and the operation environment of the operation system before the illegal shutdown can be recovered, thus realizing breakpoint restoration. Moreover, the invention also provides a breakpoint restoration system based on heterogeneous hybrid memories.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a breakpoint recovery method and system based on heterogeneous hybrid memory. Background technique [0002] Today, with the rapid development of information technology, computers have been widely used in various fields. In the process of actually using the computer, people often encounter problems such as abnormal shutdown due to unexpected power failure and other reasons, resulting in damage to system files and loss of user data. [0003] In order to solve problems such as failure to boot into the operating system and loss of user data caused by the above abnormalities, modern operating systems generally support backup functions (automatic scheduled backup, manual backup), that is, when the operating system is running normally, the current operating system The mirror image is backed up to an external storage device (such as a local hard disk, a network hard disk, etc.). The ...

Problems solved by technology

In the process of actually using the computer, people often encounter problems such as abnormal shutdown due to unexpected power outages, resulting in system file corruption and user data loss.

[0003] In order to solve problems such as failure to boot into the operating system and loss of user data caused by the above abnormalities, modern operating systems generally support backup functions (automatic scheduled backup, manual backup), that is, when the operating system is running normally, the current operating system The mirror image is backed up to an external storage device (such as a local hard disk, a network hard disk, etc.). Bootable and operational system state

[0004] The traditional operating system recovery method restores only the operating system itself. The programs and operating environment running before the system power failure cannot be restored, only the system image that has been backed up in advance can be restored, and the applications that were running before the system power failure It is not recoverable, so it cannot be counted as breakpoint recovery
