When it comes to protecting your data, not all backup strategies are created equal. In this episode, we dig deep into the evolution of backup best practices — starting with the tried-and-true 3-2-1 method, moving to the more resilient 3-2-1-1-0, and finally unpacking the enterprise-grade 4-3-2 model.
We’ll explore why each strategy was created, what risks they address, and when one might be better than another depending on your infrastructure, threat landscape, and compliance requirements. From air-gapped storage and immutability to zero-error recoveries and multi-site redundancy, we’ll translate the jargon into real-world application — no oversimplification, just actual strategy.
Whether you're managing a growing SMB environment or securing critical data in a complex enterprise setup, this discussion breaks down what it takes to create a backup strategy that’s resilient against ransomware, disasters, and human error.
