Abstract

The invention discloses a file backup method and a system, which aim at saving the memory space required by file backup, wherein the method mainly comprises the following steps: setting up splitting rules; splitting the files into a plurality of file blocks to back up according to the splitting rules; when the file is backuped again, if the file is modified, splitting the modified file to generate the modified file block based on the splitting rules; and backuping the modified file block. Compared with the prior art, the invention saves the memory space required by the file backup and the backup time, and improves the memory efficiency.

Description

technical field [0001] The invention relates to a file storage method, in particular to a file backup method and system. Background technique [0002] As computers and other electronic devices are increasingly involved in all aspects of modern work and life, users of all computers and other devices such as modern enterprises have a need for file backup. For electronic devices, any data is embodied in the form of files. With the development of computer technology and network technology, viruses, hackers and Trojan horses are always threatening the security of computer files. [0003] When computer files are lost or irreversibly damaged, it can bring heavy data disasters to users, and even cause bankruptcy and other dangers for enterprises. In this case, file backup is especially important. [0004] figure 1 It is a schematic flowchart of an embodiment of a file backup method in the prior art. Such as figure 1 As shown, the process mainly includes the following steps: ...
