调试保存输出显示

87713:save: Found prototype specification for '\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1288\Areas Compartidas\':+ skip : *.*

Cause

  1. 以管理员身份打开命令提示符并运行: 
C:\>  DISKSHADOW /l writers.txt
DISKSHADOW>   LIST WRITERS DETAILED
DISKSHADOW> exit
  1. 查看 writers.txt 的输出文件。如果您看到以下消息,则确认问题。
* 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:\]
