What are immutable backups

This episode of Techsplainers explores immutable backups and why they are a core part of modern data protection. It explains how immutable backups create read-only copies of data that cannot be altered or deleted during a defined retention period, helping organizations defend against ransomware, accidental deletion, corruption and insider threats.

The episode walks through the difference between traditional backups, immutable backups and immutable snapshots, showing how each fits into a layered recovery strategy. It also examines the technical building blocks behind immutable backups, including WORM storage, retention locks, partitioning, air gapping, continuous data protection, encryption, access controls and AI-based threat detection.

Along the way, the discussion highlights the growing role immutable backups play in cyber resilience, disaster recovery and compliance across industries such as healthcare, finance and education. Listeners will also hear practical guidance on deployment choices, backup types, regular testing and integration with broader security operations. The result is a clear look at how immutable backups help organizations preserve data integrity and maintain reliable recovery options when systems are under attack.
