Symptoms

雖然沒有 NetWorker 指令，但 Azure 上的 Windows 檔案系統會略過檔案。

偵錯儲存輸出顯示 
87713:save: Found prototype specification for '\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1288\': skip : hiberfil.sys
87713:save: Found prototype specification for '\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1288\Areas Compartidas\':+ skip : *.*

Cause

備份檔案系統位於 Azure 儲存磁片區上。系統使用 VSS 寫入器「Sync Share Service Writer」。其設計可略過檔案。

若要確認這是原因，

  1. 以系統管理員身分開啟命令提示字元並執行： 
C:\>  DISKSHADOW /l writers.txt
DISKSHADOW>   LIST WRITERS DETAILED
DISKSHADOW> exit
  1. 查看 writers.txt 的輸出檔案。如果您看到以下訊息，則會確認問題。
* WRITER "Sync Share Service Writer"
.////
and that writer contains Components with affected drive 
            - Components:
            - File List: Path = J:\DataFiles, Filespec = *.*
            - Paths affected by this component:
                - J:\DataFiles
            - Volumes affected by this component:
                               - \\?\Volume{c34a534a-63a2-4aee-b47a-e2092dc7a901}\ [J:\]
