I just can't get an advanced backup copy script to work because robocopy \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy37\Windows t:\destination /e /b /copyall (there is no space in 'Windows', the board introduces it) fails with 2009/10/15 1532 ERROR 123 (0x0000007B) Getting File System Type of Source \\ ?\GLOBALROOT\Device\HarddiskVolumeShadowCopy37\Windows\ The filename, directory name, or volume label syntax is incorrect. Source - \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy37\Windows\ Dest : t:\destination\ in all I have isolated the problem to the device name use, but there shouldn't be anything wrong with it, because COPY works with it ok, and vshadow -q outputs this * SNAPSHOT ID = {3cc5b728-bf85-422a-bf98-dff9eb497ec1} ... - Shadow copy Set: {0baefca3-7f14-4aa9-8cad-48915c59f8c0} - Original count of shadow copies = 1 - Original Volume name: \\?\Volume{96162222-1508-11de-872f-806e6f6e6963}\ [C:\] - Creation Time: 15-Oct-09 15:07:44 - Shadow copy device name: \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy37 - Originating machine: XXX - Service machine: XXX - Not Exposed - Provider id: {b5946137-7b9f-4925-af80-51abd60b20d5} - Attributes: No_Auto_Release Persistent Differential ANY ideas?!? I am not knowledgeable in windows device names so if there's a "catch" with using \\?\ let me know...only tried \\.\ instead, similar failure. (there is nothing wrong per se, if I attach this device name to a drive letter or path, robocopy will work, but it'd be way nicer to do without as there's lots of gotchas to guard for if the letter/path is not available)
