Problems solved by technology

[0002] The current operating system is mostly artificially triggered backup or self-defined timing backup when performing backups, but when people use computers, the operating system (files) often does not change significantly for a long time, that is, there is no need for backup, and there are also users. Significant changes have been made to the operating system during one use, requiring a backup
Manually triggered backups or scheduled backups often ignore such backup requirements, resulting in either repeated meaningless backups or missing backups

Abstract

Embodiments of the invention provide a backup method and device. The method comprises the steps that a current partition table and a historical partition table of an operating system are obtained, wherein the current partition table records storage information of a target storage area when the operating system is in a current to-be-started state, and the historical partition table records storage information of the target storage area corresponding to each to-be-started state of the operating system within historical time; and based on the contents recorded in the current partition table and the historical partition table, whether to back up the storage contents of the current target storage area or not is determined. According to the backup method, whether backup is carried out or not can be automatically selected according to an actual backup condition, and data backup precision and efficiency are improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, and in particular to a backup method and device. Background technique [0002] The current operating system is mostly artificially triggered backup or self-defined timing backup when performing backup, but when people use the computer, the operating system (file) often does not change significantly for a long time, that is, no backup is required, and there are also user Significant changes have been made to the operating system during a certain use, requiring a backup. Artificially triggered backups or scheduled backups often ignore such backup requirements, resulting in either repeated meaningless backups or missing backups. Contents of the invention [0003] The invention provides a backup method and a backup device capable of automatically selecting whether to perform backup according to the actual backup situation. [0004] In order to solve the above technical...
