All,

I'm familiar with http://www.cygwin.com/cygwin-ug-net/using-specialnames.html

But it only shows the \device\hardisk mappings.

Are there also mapppings for the shadow devices.
(http://en.wikipedia.org/wiki/Shadow_Copy)

ie.
\Device\HarddiskVolumeShadowCopy4
or
\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy4

If your running Vista or Win2008 you can create a shadow copy device
by going to the file explorer, right clicking on a local NTFS drive,
clicking properties, then the "shadow copies" tab, then create now.

To get the instance number (4 above) you go to the command line and
type "vssadmin list shadows".

In theory I should be able to mount that under cygwin and access my
snapshot-ed filesystem.

My personal desire is make a full dd copy of a snapshot onto a external drive.

ie. dd if=/dev/sd-shadowcopy4 of=<my_image_file>

Thanks
Greg
