Abstract

The invention provides a data backup method and electronic equipment. The data backup method is applied to the electronic equipment. The electronic equipment comprises a nonvolatile memory. The data backup method comprises the steps that data are written into the nonvolatile memory; snapshots of the data are established, and the data, corresponding to the snapshots, serves as a protected area which cannot be rewritten; a current mapping table is copied, and corresponding relations of physical addresses of the data corresponding to the snapshots in the nonvolatile memory and logical addresses of the data are established in the mapping table; the mapping table which serves as an initial mapping table is stored into a particular area of the nonvolatile memory.

Description

technical field [0001] The present invention relates to the field of electronic equipment, and more particularly, the present invention relates to a data backup method of non-volatile memory and electronic equipment. Background technique [0002] At present, almost all electronic devices have an operating system pre-installed before leaving the factory. To this end, a preload partition is provided in the storage device of the electronic device for recovery of the preinstalled system. The purpose of this partition is to back up the current pre-installed system so that the user can restore to the factory state if something goes wrong. Although the content of this partition is exactly the same as the system in use in the user's system when it leaves the factory, because the user's system will change during use, although this change is not large, for example, the Windows system is installing a service pack (service pack) containing major updates. pack), it only changes by no m...
