5 reasons Microsoft 365 backup isn’t enough for business data protection

Microsoft 365 operates under a shared responsibility model where data protection is the customer's responsibility, not Microsoft's. Five key gaps are outlined: native tools don't protect against ransomware or malicious data loss (version history is insufficient against sophisticated attacks), retention policies don't meet many compliance requirements for long-term storage, granular recovery is slow and complex, phishing and insider threats can cause data loss that requires manual recovery, and native backup options are not cost-efficient at scale for growing organizations or MSPs. Third-party solutions combining immutable storage, AI-based ransomware detection, granular recovery, and scalable pricing are recommended to fill these gaps.
