Notes-

• We cannot create trigger on 'Object' or 'Field'.
• Alternative is creating a Batch Class and schedule it as per the requirement.
• To store the history of the fields we can user either list custom settings or custom object.
• List Custom Settings is not supporting Text Area Long.
• To store the history of the fields we need Text Area Long (255 character for text area data type is not sufficient.) field which is possible with the custom object.
