意外地能够为FAT32卷创buildVSS卷影副本

在做一些testing时,我们发现我们意外地能够使用一些调用VSS API的现有代码为FAT32卷创build卷影副本,但是,我无法使用wmic shadowcopy call create Volume='E:\'在同一卷上创build卷影副本wmic shadowcopy call create Volume='E:\'

我在网上看到的一切都说这不应该是可能的。 所以我的问题是:

  1. 是否有可能为FAT32卷创build卷影副本?
  2. 如果不是,我在下面看到了什么?
  3. 如果是这样,哪个Windows版本引入了这个function?

谢谢你的帮助。
