How to create a Backup with appcmd in IIS

After you install IIS 7.0, you can backup your configuration by using the built-in command-line tool, AppCmd.exe. You can run AppCmd.exe to create a backup of your Web server before you have changed any configuration.

To create a backup using AppCmd.exe

1. Open a command prompt as administrator and change to the %windir%\system32\inetsrv\ directory.
2. At the command prompt, type appcmd add backup “FirstBackup” and then press Enter.

This creates a backup with the name “FirstBackup”.

At a later date, if you need to restore the backup, use appcmd restore backup “FirstBackup”.
