I am attempting to copy some files from a windows 2008 server using diskshadow.
I am using the following script:
#DiskShadow script file
set context persistent nowriters
set metadata c:\copydata\backup.cab
set verbose on
add volume c: alias SystemVolumeShadow
add volume d: alias DataVolumeShadow
expose %SystemVolumeShadow% p:
expose %DataVolumeShadow% q:
delete shadows exposed p:
delete shadows exposed q:
#End of script
if i use xcopy in c:\copydata\backupscript.cmd I get "access denied" errors along with "0 files copied" however the files and datestamps are copied, but not the contents of the files.
if i use robocopy in c:\copydata\backupscript.cmd I get no errors however nothing is copied.
Is there a command which will copy files from a shadow copy created with diskshadow in the same manner as xcopy could be used with shadow copies created with vshadow.exe.
Alternatively if there was a way I can select a nas drive as the target for a backup using "Windows Server Backup" as that would do instead.
Thanks in advance for your assistance

I would suggest trying the following syntax:
robocopy X:\shadowcopy\dir\dir Y:\dir /S /XJ /COPY:DAT /NFL /NDL /w:0 /r:0
The header information:
- I am copying only the dir/dir directories (change as required)
- X being the source drive
- Y being the destination drive
- *.* indicates to copy all files
- /NDL suppresses directory listings to the console
- /NFL suppresses file listings to the console
- /S copies the source folder and all sub folders and files
- /COPY:DAT copies data, attributes and timestamps
- /XJ exclude junction points
- /R:0 number of retries on failed copies (in other words -do not re try - Edit to taste)
- /W:0 wait between retries

Monday, June 18, 2012 8:21 AMThanks for your response. The robocopy syntax you suggested was essentially what I was doing. I re run the same batch file the following day and this time it performed as expected. A bit worrying that the same code produces different results on different days, but at least it works now. So thanks again.
