According to
http://sourceware.org/ml/cygwin/2007-05/msg00359.html
http://sourceware.org/ml/cygwin-patches/2006-q4/msg00008.html
Cygwin includes support to mount a //?/GLOBALROOT/... path
But it does not work for me
(Tested on XP SP2 with 'vshadow -wait C:' running):
Cygwin 1.7.0-31:
# mount '//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy1' /tmp/vss1
# mount
C:OBALROOT\Device\HarddiskVolumeShadowCopy1 on /tmp/vss1 type unknown
...
Cygwin 1.5.25-15:
# mount '//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy1' /tmp/vss1
mount: /tmp/vss1: Invalid argument
Same when using '\' instead of '/'.
Workaround: Map VSS volume to a drive letter X:
