整理旧的 Windows Server Backup 快照

我正在从计划作业运行 wbadmin，将我的 C：和 D：驱动器备份到我的 E：并且（我相信！）包括系统状态：

wbadmin start backup -backuptarget:e: -include:c:,d: -allCritical -noVerify -quiet

我想删除旧备份，但我担心我能找到的所有信息都说要wbadmin删除旧的系统状态备份，并vssadmin删除其他备份。据我所知，我的备份是系统状态备份，但使用 E: 上的 VSS 进行存储，所以我担心尝试这两种技术中的任何一种，因为我担心会丢失所有备份。

这是一个家庭网络，所以我没有多余的服务器来测试。

我也很乐意简单地限制在 E: 上使用的空间，但我无法理解相关命令的/for和参数之间的区别。/onvssadmin

作为参考，以下是输出vssadmin show shadows：
