我从一个预定的工作中运行wbadmin，将我的C：和D：驱动器备份到我的E：和（我相信！），包括系统状态：
wbadmin start backup -backuptarget:e: -include:c:,d: -allCritical -noVerify -quiet 我想删除旧的备份，但是我担心所有可以find的信息都表示使用wbadmin删除旧的系统状态备份，而使用vssadmin删除其他备份。 据我所知，我的备份是系统状态备份，但在E：上使用VSS进行存储，所以我担心这些技术中的任何一种都会因为担心丢失所有备份而担心。
这是一个家庭networking，所以我没有备用服务器来testing这个。
我也很乐意简单地限制E：上使用的空间，但我无法理解相关vssadmin命令的/for和/on参数之间的区别。
作为参考，这里是vssadmin show shadows的输出：
