We have demonstrated in one of our previous screencasts - How to Troubleshoot Metabase Corruption - Exchange 2000/2003, using MetaEdit / Metabase Explorer for Metabase troubleshooting.

In this screencast, we will demonstrate how to backup and restore Metabase in IIS6. We will start with the more difficult scenario, when the IIS services are down, and you have to restore manually Metabase, using history files.
You will see, also, how to backup and restore Metabase, using IIS manager – IIS services have to be Up and Running.
