摘　　要：介绍了裸机备份与恢复的概念,指出了裸机备份恢复技术与普通数据备份恢复技术的异同点,并分析了当前主流裸机备份恢复软件的优缺点。在分析Windows系统和Linux系统启动流程的基础上,给出了制作基于U盘上的Linux恢复平台和基于光盘的Windows恢复平台的方法。在Windows系统下实现了一个完整的裸机备份恢复系统,阐述了该软件的详细设计,包括需备份信息的分类、信息保存的结构,以及该软件的创新点技术——打开文件备份和虚拟加密磁盘技术,说明了软件的工作流程。该系统在备份成本、恢复时间方面达到了较好的效果,在数据存储的安全性方面具有创新性,是国内首个具有自主知识产权的裸机恢复软件。Firstly, this paper introduced the data backup and recovery technology, explained the significance of this technology. It introduced the definition of bare metal backup and recovery, pointed out the difference between bare metal backup ＆ recovery and common backup ＆ recovery, analyzed the merit and defect of current popular bare metal backup and recovery software. Secondly, explained the Windows and Linux system boot process, discussed the methods to do bare metal backup and recovery for Windows system and Linux system in detail, and pointed out the key problems and solutions. It indicated the importance of recovery platform for bare metal recovery, put forward the methods to make a bootable Linux system on U-disk and a bootable Windows system on optical disk. Finally, implemented a completely bare metal backup and recovery system for Windows. Moreover, the software achieved good performance and security＇ in contrast to traditional bare metal backup and recovery software because the new system makes use of some new technologies such as open file backup and virtual encrypted disk.
