Do I need to retain records of my website's contents?
The short answer: Yes, for a minimum of 2 years to meet Reg. DD TISA requirements
The Federal Financial Institutions Examination Council (FFIEC) states:
Record retention provisions apply to electronic delivery of disclosures to the same extent required for non-electronic delivery of information. For example, if the web site contains an advertisement, the same record retention provisions that apply to paper-based or other types of advertisements apply1. Copies of such advertisements should be retained for the time period set out in the relevant regulation. Retention of electronic copies is acceptable.
1 AdvisX Risk Management's Record Retention Schedule for Banks states that copies of advertisements must be retained for 2 years.
