[This is preliminary documentation and subject to change]
By default, the metabase history feature is enabled and the number of history file pairs that are saved within the history folder is defined by the default value of the MaxHistoryFiles property. A history file pair is the combination of a copy of a MetaBase.xml and a MBSchema.xml file of the same version within the history folder. By default, the following properties are not written within the MetaBase.xml file, and IIS implies the absence of the following properties to mean that the history feature in enabled and the MaxHistoryFiles property is set to the default value.
To change the metabase history default settings, you must add the following metabase properties to the /LM level of the metabase.
To disable metabase history, set the value of the EnableHistory property to 0 (zero). To enable metabase history, set the value of the EnableHistory property to 1 or remove the EnableHistory property from MetaBase.xml.
To change the number of history files that are stored within the history folder, change the value of the MaxHistoryFiles property. When the value of the MaxHistoryFiles property is set to 0 (zero), the default value will be used.
