AI Bookkeeping Backup and Disaster-Recovery Strategies for 2026 Introduction: Why 2026 Is a Make-or-Break Year for Data Resilience The global cost of poor data-protection practices keeps climbing. IBM’s Cost of a Data Breach Report 2025 pegs the average incident at US $4.45 million—up 15% since 2021.¹ As more businesses adopt AI-enabled finance applications, more ledgers, forecasts, and audit trails are created by machine logic rather than humans.
