AppCmd backup for IIS7 gives access denied error (hresult:80070005)

I have a script I have been using on another Windows 2008 to delete the IIS7 backup of configs and create a fresh one:

SET DEST=C:\Backup\Web\IIS7
SET BACKUPNAME=IIS7-CONFIGS
%windir%\system32\inetsrv\appcmd.exe delete backup "%BACKUPNAME%"
%windir%\system32\inetsrv\appcmd.exe add backup "%BACKUPNAME%"
robocopy %windir%\system32\inetsrv\backup "%DEST%" /MIR /R:6 /W:10 /ZB

But on a new Windows 2008 server, I get an access denied on the delete:

ERROR ( hresult:80070005, message:Command execution failed.
Access is denied.
 )

I have UAC turned off and pretty much copied all the settings from the old server (including user role being an admin). What am I missing?

Solution 1:

Old post I know but same issue here just now. I realized then I did not run the "cmd" as an Administrator

So ran CMD as an Administrator and it ran fine.

Solution 2:

I had a similar issue running

%systemroot%\system32\inetsrv\APPCMD.EXE migrate config "Default Web Site/MyWebApp"

I was getting 80070005 Access Denied.

I found out the issue was due my web.config being read only (as I used a source code management system that download as read only the files not checked out by the developers).

Removing the read only attribute from the web.config, fixed the issue.

I suppose you have to remove the read only attribute from some config file which should be touched by the above commands.
