VShadow issue

[phlegmer]

Greetings,

I'm not sure if this is the appropriate forum to pose this problem so if it isn't please point me elsewhere.

I'm writing a script for our facility that will allow the user to backup parts of their HDD to the server. I want to utilize VShadow.exe in order to get around locked .PST files when this script gets run. The script will be on a network share for the end users to launch (or maybe even schedule). The basics of the script will be similar to

I can get it to work just fine when I do everything local, the problem occurs when I try to do it from a shared mapped drive. Here is the call I'm making from the script:

z:\vshadow.exe -script=vss-setvar.cmd -exec=vss-exec.cmd c:


The following are the errors I get when running it from the mapped drive:

VSHADOW.EXE 2.2 - Volume Shadow Copy sample client

(Option: Generate SETVAR script 'vss-setvar.cmd')
(Option: Execute binary/script after shadow creation 'C:\Windows\Temp\VSS\vss-exec.cmd')

ERROR: Win32 call "GetVolumeNameForVolumeMountPointW((LPCWSTR)volumeRootPath.c_str(), WString2Buffer
(volumeName), (DWORD)volumeName.length())" failed.
- GetLastError() == 3
- Error text: The system cannot find the path specified.

- Please re-run VSHADOW.EXE with the /tracing option to get more details


I then ran -Tracing on a successful local instance and also when it fails from the remote drive. Here is the difference I noticed:

Even though I specify C: in the command, it still tries to do z:.

This is running on an XP SP3 client box.

Please advise and thanks!

Figured out a fix myself.

Copy the vshadow files to a temp dir on the pc, then use the START command along with the temp path specified fixes the problem.
