The backup operation that started at '?2011?-?2?-?5:' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '0x80780021'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved

查找到已有MS博客描述類似問題，在遵循其方法后問題依然存在，已進行如下修改:
在注冊表:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\SPP
創建新DWORD值命名為"CreateTimeout",值為12000000.

發現博主可能忽略其他一些相關操作，在進行上述注冊表操作后要進行以下操作:

重啟 BITS, VSS 和Com+ event system 服務，注意BITS服務重啟會中斷系統更新等依賴服務.
