我需要通过命令提示符以最less的停机时间来备份正在运行的Hyper-V虚拟机。 备份应该存储在另一个本地磁盘或远程共享上。
以下是用于使用VSS备份Hyper-V以创build快照的示例脚本。 在快照期间，不支持VSS的客户机操作系统将进入保存状态。
此示例将位于E：\ VS目录中的映像备份到F：\ VS Backups中的本地目录中。 这些地点将需要调整，以适应您的需求。 对于每个源驱动器，都需要将额外的卷添加到VSS快照。
Technet上提供了有关 diskshadow.exe命令的文档。
将这三个文件中的每一个复制到一个目录并运行HyperVBackup.cmd 。
HyperVBackup.cmd：
REM Use the diskshadow command to support "live" Hyper-V backup REM though VSS diskshadow /s diskshadow_script.txt > HyperVBackup_LOG.txt REM Remove CAB files which are generated to support the exporting REM of disk shadow copies (not required here) del *.cab /Q diskshadow_script.txt：

HyperVBackup_exec.cmd：
