VSS SYSTEM FILESET Always failed

This is most likely due to a problem with the appropriate VSS writer. These fail sometimes.

Please check with "vssadmin list writers".

To repair it on a Windows 2008 server, logon with admin accounts and run the following commands (/script):

Takeown /f %windir%\winsxs\filemaps\* /a

icacls %windir%\winsxs\filemaps\*.* /grant "NT AUTHORITY\SYSTEM:(RX)"

icacls %windir%\winsxs\filemaps\*.* /grant "NT Service\trustedinstaller:(F)"

icacls %windir%\winsxs\filemaps\*.* /grant BUILTIN\Users:(RX)

net stop cryptsvc

net start cryptsvc

net stop nsrexecd

net start nsrexecd

net start nsrpsd  <--- NW 8.1.+

Please check again with "vssadmin list writers". the problem should have been solved.

Then retry the backup.

Yep, probably this is the best way in our case. Moreover we are scheduled update. But we need to keep our savesets alive this time

Thank you very much.Will try today

Tried vssadmin list writers. I dont see any errors, all of writers in Stable condition. Other commands will be executed later today.

The same conditions on other servers.

Are you still getting an error after upgrade ? id yes, please share the error here.

No, we just planning to upgrade NW. Current version is 7.6.5.It will be completed in 2 months. Is it possible to fix VSS SYSTEM FILESET issue before update?

Do you have VSS patches installed for win2k8?  Did you check event logs for time when error was logged?

Servers are on remote site. Im waiting for EventLogs now. Do you have a list of patches to check?

Some of those I know about...

Ok, now it's clear. So do I need to update client to last version and it should be ok?

Yep. You are correct !

Crazyrov, thank you very much!. Everything is OK after client update!! Thank you all for your help
