Hello All, We are using Networker 7.4.4 in windows server 2008 and vista machine. We are facing problem during file system backup. 1) We had disabled the VSS but still Networker is taking VSS backup. 2) During backup backup for other save set is successful except for 'VSS SYSTEM FILESET'.

System Writer - Error saving file path C:\windows\inf\display.inf that is associated with Shadow Copy path \?\GLOBALROOT\Device\HarddiskVolumeShadowCopy126\windows\inf\display.inf.

I think David wants to know exactly what steps did you do to disable VSS, something may be missing and further steps may be needed.

Thanks Daniel. Yes, if we can first see what steps you have taken to disable VSS we can decide whether you have made an error there or if the problem is something that needs further investigation.

Hello,Disabling VSS on a win2k8 server won't work.You should see a message like:Save Operations value is ignored on this OS platform.The reason why you get the errors, is that VSS thinks the files are in that location (C:\windows\inf\display.inf), but when you look in that location, you will see that you won't find it there.So why does VSS think it is there? 2 reasons: - somewhere in the registry you will find an entry C:\windows\inf\display.inf Change this to the real location of the display.inf - When installing a server, VSS makes a list of all it's files. When moving applications or files, this list is not updated. You can bypass this doing the following: 1. Add NSR_IGNORE_MISSING_SYSTEM_FILES system environment variable with a value of 1. The system environment variable needs a reboot! 2. Create 'filesallowedtoskip' file under nsr\res. 3. Add files with the list of files allowed to skip in 'filesallowedtoskip' files with one full file path per line. 4. Save the VSS save set on a NW client should pass without missing file errors

Hell Timth, Thanks for the information.Even i got information that VSS can't be disabled on windows 2008.I'll try steps mentioned by you. but in the same machine windows vss backup tool (wbadmin i.e NTBackup in windows 2003) is working fine. Which means there is a bug in EMC Networker.ThanksWith RegardsHemant.

Nope.. it may mean, and most probably that is the case, that system calls used by API are broken. NT backup does not use all API calls NW does.

Also you state that NT backup works on Windows 2003. Does it fail to back up the VSS SYSTEM FILESET save set from Windows 2008?

sameer_sehgal · Answer

Please Put below command in client backup command line

save.exe -a '"ignore-all-missing-system-files=yes"' in the backup command field and try the backup to see if it works.

It will ignore all the files which are not on the system
