Abstract

The invention discloses a file backup method. A proper backup program is dynamically selected according to a file type to back up a file. The file backup method comprises the following steps of: acquiring a file list from source equipment; sequentially selecting a file to be backed up according to the file list, and acquiring the basic information and special information of the file to be backed up respectively; sequentially judging whether the acquired file to be backed up is a special file or not; when the file to be backed up is the special file, reading the data contents of the file to be backed up, and backing up the file to be backed up to target equipment according to the special information by using a volume backup program; and when the file to be backed up is not the special file, reading the data contents of the file to be backed up, and backing up the file to be backed up to the target equipment according to the basic information by a file backup program.

Description

technical field [0001] The invention relates to a file backup method, in particular to a file backup method for dynamically selecting an appropriate backup program according to file types. Background technique [0002] The definition of backup refers to a method of reading the data to be backed up from the source device, and storing the data to be backed up into the target device for backup after proper processing. Generally speaking, backup is a means of protecting important data security, that is, if the data of the source device is damaged, as long as the backup is made before the data is damaged, the data stored in the target device can be used to restore the source data in the device. [0003] At present, backup tools are basically divided into two categories: file backup tools and volume backup tools. File backup tools are used to back up specific files and directories specified by users. After being read from the file system operation interface, they are backed up th...
