系统驱动器到磁盘克隆

我正在尝试找到一种方法将活动的Windows系统磁盘克隆到另一个磁盘而不强迫用户使磁盘脱机,如Clonezilla要求。

我正在考虑至少部分答案的Microsoft卷影复制服务(VSS)。 (我完全乐于接受更好的思考/解决方案。)

在继续使用代码示例之前,我对VSS有点犹豫(.Net接口使用通过NuGet Package Manager提供的AlphaVSS),因为两个使用VSS(Shadow Copy和另一个工具)的实用程序没有复制驱动器正常。并非所有文件都被复制,尤其是根目录中的sys文件,并且未复制完整权限。简单的Araxis磁盘比较显示了副本的不准确性。此外,我无法启动克隆的驱动器。我得到一个屏幕,说驱动器无法启动,必须​​进行修复。

样本有点难以理解。我期待看到包含开关(子目录与非,权限等等)

我确实看过dotNetDiskImager,但那是USB到图像文件和图像文件到USB磁盘。修改代码,以便一个人开车去潜水是完全失败。人们不能只是愚蠢地复制部门。一个人必须知道你在复制和修改。复制扇区并不是一项简单的任务,因此可以回到VSS。

有更好的想法吗?

这是一个更新的AlphaVSS代码,它修复了由于AlphaVSS同步而非异步而导致的编译器错误。我还将代码从VB转换为C#。

简而言之,我想采用一个实时系统磁盘,它通常包含"系统保留",#34; main"和恢复分区,并对另一个进行实时克隆系统中的磁盘。

我会确保新磁盘有足够的空间,已经分区并格式化为3个NTFS分区。
