From 3-2-1 to 4-3-2: How Many Backup Copies Are Enough?
Description
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.
