IIS Metabase

Microsoft's Internet Information Services stores its information in an internal database called the MetaBase. The metabase is an inheritable, hierarchical database that allows for configuration of HTTP/HTTPS, FTP, SMTP, and NNTP at the server, the site, or the folder or file level. Different versions of IIS use different formats; prior to IIS version 6 this was always a proprietary format, whereas with 6.0 and later the data is stored in XML files. The metabase consists of two files, MetaBase.xml and MBSchema.xml, stored in the %SystemRoot%\system32\inetsrv\ directory. The metabase periodically gets backed up to the MetaBack subdirectory. When Internet Information Service starts, it reads the two metabase files to create an in-memory cache of the web server's configuration, which is referred to as the in-memory metabase. Changes to the IIS configuration via the IIS Manager or programmatic changes get written to the in-memory metabase, then are persisted to the on-disk MetaBase.xml file after a number of changes.
