Cloud Resilience Isn't Backup: INCD Warns Against Data Loss Risks
Many organizations utilizing cloud infrastructure may mistakenly rely on the built-in resiliency and redundancy mechanisms provided by major cloud vendors like AWS, Azure, and Google Cloud as a substitute for proper data backups. While these features are designed to ensure service uptime and availability, they do not offer protection against data loss, corruption, or malicious deletion, such as that caused by ransomware attacks.
The Israel National Cyber Directorate (INCD) highlights that assuming cloud provider redundancy negates the need for backups is a critical oversight. These inherent cloud capabilities are focused on service continuity in the face of hardware failures or localized outages, not on safeguarding data from logical errors, accidental deletions, or sophisticated cyber threats that can compromise entire datasets.
Organizations must understand the distinction between availability features and data protection strategies. A robust backup plan is essential to ensure data recoverability in scenarios where cloud provider resiliency mechanisms are insufficient.

What This Means For You
- Verify and implement a comprehensive data backup strategy tailored to the sensitivity and criticality of your information within your specific cloud environment, as cloud provider redundancy alone does not constitute a sufficient backup solution.
