摘要: 针对文件分配表文件系统数据的安全保障需求,基于符合统一可扩展固件接口(UEFI)规范的EFI开发套件2(EDK2)开源环境,提出一种固件层数据备份与恢复技术。利用EDK2提供协议接口读取硬盘分区数据,将获取的文件及目录信息备份为EFI镜像文件格式,数据恢复时反向写入目标分区。实验结果表明,该技术可解决传统数据备份对操作系统的过度依赖问题,其在固件层实现数据备份,实用性更强。

Abstract: Aiming at the target of protecting File Allocation Table(FAT) file system data security, based on EFI Developer Kit 2(EDK2) open source environment defined by Unified Extensible Firmware Interface(UEFI) specification, this paper proposes a technology of data backup and recovery on firmware level. After using the protocols EDK2 provided for accessing disk partition data. It gets details of files and directories by calculating, and saves them as EFI image file, which will write into destination partition when the recovery module works. Comparing to legacy data backup technology, this technology works on firmware level, is independent of operating system, and this advantage makes it more usable.

Key words: Extensible Firmware Interface(EFI), data backup, data recovery, EFI Developer Kit 2(EDK2), file distribution list system
