vital records

Among information assets, documents related to the survival of the organization and documents for which no other alternative information is required.

They include design drawings, sketch drawings, quality control materials, etc., documents necessary for recovery, alternative production, etc., documents for securing control, legal compliance and accountability, documents for establishing rights and obligations, and documents for securing debts and credits (based on the Business Continuity Guidelines issued by the Cabinet Office, Government of Japan).
However, the scope of these documents is also wide, ranging from "those essential in an emergency" to "those that need to be only retained." Therefore, if all these documents were to be handled uniformly, it would be more time-consuming and costly than necessary, and would be difficult to maintain.
Which vital records are needed will vary depend on the size and type of disaster, as well as the amount of time that has passed since the disaster occurred.
In general, it is estimated that they account for around 5 to 7% of all the information possessed by an organization.

(Explanation of the figure) Which vital records are needed will vary over time.
JIIMA has established and distributed recommendations to provide guidance for responding to these issues.
