You can back up and restore the Forefront TMG configuration using Volume Shadow Copy Service (VSS). VSS is a set of Component Object Model (COM) application programming interfaces (APIs) that provide standardized interfaces, enabling third-party backup and restoration software to centrally manage the backup and restore operations on a variety of applications. In Forefront TMG, the configuration is stored in an instance of Active Directory Lightweight Directory Services (AD LDS). When you use VSS to back up and restore the Forefront TMG configuration, Forefront TMG calls the AD LDS VSS Writer.
Ensure that you back up the required server, depending on whether it is standalone or belonging to an array, as follows:
- Enterprise array—Back up the Forefront TMG
Enterprise Management Server (EMS).
- Standalone array—Back up the array
- Standalone server—Back up the Forefront TMG
