Avamar windows system state backup failure.

One of the work around for system state backups. First install the New 6.0.1-66 client - AvamarClientWindows-x86_x64-6.0.101-66._HF34148.msi or later versions on the windows client.


 
Symptom

System state backup failed with the following error message:
"System writer is not found"

In addition, when you run the “Vssadmin list writers” command to display VSS writers on the system, the System Writer is missing.


Cause
The system writer fails due to the fact that the trusted installer & system accounts are missing permissions to files in the directory %windir%\winsxs\filemaps\.

Resolution
To resolve this issue, please run the following commands from an administrative elevated Command Window:

CD c:\windows\system32
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)"

Applies to
Windows Server 2003, Windows Server 2008
