Definition
You can select certain fields to track and display the field history in the History related list of an object. When Field Audit Trail isn't enabled, field history data is retained for up to 18 months, and up to 24 months via the API. If Field Audit Trail is enabled, field history data is retained until manually deleted. You can manually delete field history data at any time. Field history tracking data doesn’t count against your data storage limits.
