Vista - Win32_NTEventLogFile BackupEventLog: Access denied

I have some trouble calling BackupEventlog. Even if I'm logged on as an
Administrator I get an access denied error:

PS H:\> $log=gwmi "Win32_NTEventLogFile WHERE LogFileName='Application'"
PS H:\> $log.BackupEventlog("C:\Test.evt")
Ausnahme beim Aufrufen von "BackupEventlog": "Zugriff verweigert. "
Bei Zeile:1 Zeichen:20
+ $log.BackupEventlog( <<<< "C:\Test.evt")

The scripts found on the internet are using something like this when
binding to wmi:

"{impersonationLevel=impersonate,(Backup)}!\\"

How can this be done in PS?

Stick this line in the mddle.

$log.PSBase.Scope.Options.EnablePrivileges = $true
