In this episode, we delve into the world of immutable backups, a crucial component of modern data protection strategies. We explore why immutable backups have become increasingly important in the face of sophisticated cyber threats, especially ransomware attacks that target backup systems. The episode covers the evolution from tape backups to disk-based systems and cloud solutions, highlighting how this shift has introduced new security challenges.

We discuss the spectrum of immutability in backup systems, from basic file system protections to fully immutable cloud storage options. The conversation touches on various implementations of immutable backups, their strengths, and potential vulnerabilities. We also address the importance of multi-factor authentication and awareness of emerging threats like AI-based voice impersonation.
