我在 Windows 7 Ultimate PC 上使用卷影复制时遇到问题。基本上，我无法使用任何依赖卷影复制的程序，因为它们总是会失败（包括 Windows 备份），并出现一整串错误（取决于程序）。例如，当我运行 Windows 备份时，我得到：
The backup was not successful. The error is: Windows Backup failed while trying to read from the shadow copy on one of the volumes being backed up. Please check in the event logs for any relevant errors. (0x81000037).
然后我收到此 VSS 错误：
Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied.
. This is often caused by incorrect security settings in either the writer or requestor process.
Operation:
Gathering Writer Data
Context:
Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220}
Writer Name: System Writer
Writer Instance ID: {33e11ab5-bc29-4cd0-b993-656570b23fe3}
然后，当我运行 Paragon System Backup（版本 9.5）时，我得到以下信息（它告诉我 VSS 存在问题）：
Volume Shadow Copy Service information: The COM Server with CLSID {4e14fba2-2e22-11d1-9964-00c04fbbb345} and name CEventSystem cannot be started. [0x80070013, The media is write protected.
]
Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x80070013, The media is write protected.
.

]
Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x80070013, The media is write protected.
.
然后我收到一条信息消息说：
The VSS service is shutting down due to idle timeout.
（昨天我尝试运行备份时得到了 5 个这样的错误）
然后我收到这些警告：
Volume Shadow Copy Service warning: VSS was denied access to the root of volume \\?\Volume{2d3b403a-2f5a-11df-846a-005056c00008}\. Denying administrators from accessing volume roots can cause many unexpected failures, and will prevent VSS from functioning properly. Check security on the volume, and try the operation again.

当我运行 vssadmin list writer 时：
Writer name: 'Task Scheduler Writer'
Writer Id: {d61d61c8-d73a-4eee-8cdd-f6f9786b7124}
Writer Instance Id: {1bddd48e-5052-49db-9b07-b96f96727e6b}

答案1
你可以\\?\Volume{2d3b403a-2f5a-11df-846a-005056c00008}\用 Junction 替换你的 Mounted Volume，错误就会消失；微软的MSKB 文章说错误0x81000037
“如果重新解析点是已安装卷包含压缩文件（例如多媒体文件、.zip 文件等）”
（重点是我的）
使用硬链接 Shell 扩展您可以创建“连接点”来替换当前正在使用的“已安装卷”。这是我用鼠标右键单击 CD 驱动器拖入文件夹时获得的 HardLinkShellExt 上下文菜单：
- 不起作用：备份中包含库中包含的“已安装卷”：
- 是否有效：备份中包含库中包含的“连接点”：
