IISComputer::Restore
The Restore method restores the metabase from a backup. The restore operation stops all services dependent on IISADMIN, including all servers, until the restore has completed, then restarts all services. You should plan for this service interruption when restoring the metabase from a backup.
HRESULT Restore(
BSTR bstrLocation,
LONG lVersion,
LONG lFlags
);
Parameters

[in] Long integer containing the version number to be assigned to the backup. Must be less than or equal to MD_BACKUP_MAX_VERSION (9999). Can be set to MD_BACKUP_NEXT_VERSION (0xffffffff) which automatically selects the next available version number. These constants are defined in the Mddefw.h header file.lFlags
[in] Reserved. Must be zero.
