Format file backup method

The invention discloses a formatted file backup method. The method is based on cloud backup of files, a kernel monitoring program is installed in a client computer, the kernel monitoring program automatically identifies and encrypts disk storage data of formatted files, and the disk storage data, the data size, the file position, the file name, the file size, the disk storage time and the like are stored in a server side. And a user database is established at the server, and the client cannot be installed after password verification fails, so that the data stored at the server by the user can be prevented from being illegally stolen by someone. And the client application program can obtain the disk storage data of the specified file at the specified time from the server and generate the file. 一种格式文件的备份方法。本发明是基于文件的云备份，在客户端计算机安装内核监控程序，内核监控程序自动识别格式文件的存盘数据并加密,将存盘数据、数据大小及其所在文件位置、文件名、文件大小、存盘时间等保存到服务端。在服务端建立用户数据库，客户端口令验证失败不能安装，可防止有人非法窃取用户保存在服务端数据。客户端应用程序能够从服务端获取指定文件在指定时间的存盘数据并生成文件。
