Back Up All Group Policy Objects using Backup-GPO and the Group Policy Management Console

Here are a couple of quick methods to backup all of your group policy objects in one hit. The first uses the Powershell cmdlet Backup-GPO. On a Windows Server 2008 domain controller fire up Powershell, and issue the following command, where C:\PATH_TO_BACKUP is the path where you want to save the backup:

Backup-GPO -All -Path C:\PATH_TO_BACKUP

The second method uses the Group Policy Management Console. Fire up gpmc.msc, and then expand your domain. Right click on ‘Group Policy Objects’ and then choose ‘Back Up All’ as shown below:
