使用Windows Api+Qt做的一个系统备份工具
由于公司应用大量装机的情况,以前使用ghost软件来处理,但是自从uefi模式出现后ghost已经不能很好的应用了,虽然现在有Acronis软件替代,但是生成的备份文件没有很好的工具去修改,所以遇到需要添加镜像驱动和补丁的时候带来非常大的麻烦。系统自带的dism工具确实好用,但是每次都需要输入命令行输入,效率不能提高。因此根据现在的实际情况,清明三天假连学带做了这款窗口版的备份还原工具,功能目前很很简单,只有备份分区(文件夹)和还原分区功能,下一步会添加驱动添加功能。废话不说,上代码。

bcdboot 代码就不贴了,简单的都不不好意思。。。
