各位大大

最近伺服器備服的時候出現了如下error

The shadow copy provider had an error. Check the System and Application event logs for more information.
Retrying snapshot creation attempt (Unknown status of async operation
The shadow copy provider had an error. Check the System and Application event logs for more information.
--tr:Failed to create VSS snapshot.
--tr:Failed to perform pre-backup tasks.)
Task has been rescheduled
Unable to allocate processing resources. Error: Unknown status of async operation
The shadow copy provider had an error. Check the System and Application event logs for more information.
--tr:Failed to create VSS snapshot.
--tr:Failed to perform pre-backup tasks.

在網上查了很久, 己檢查c 的shadow copy config 為nolimit
但都不成功, 有沒有大大知道如何解決?
