What is an important strategy of business continuity planning?

While data encryption is crucial for securing sensitive information, it primarily focuses on protecting data during transmission or storage rather than ensuring business continuity. Encryption safeguards data from unauthorized access but does not directly contribute to the immediate availability of duplicated information in emergency scenarios.

User authentication plays a role in verifying the identity of individuals accessing systems or data. While important for security measures, user authentication is not a specific strategy within business continuity planning. Ensuring proper user access does not directly address the need for redundant data backups to maintain operations during disruptions.

Service variety refers to diversifying the range of products or offerings within a business to cater to different customer needs. While diversification is a valid business strategy, it is not directly related to business continuity planning, which focuses on preparing for and recovering from potential disruptions to critical operations.
