Field notes on backup strategy, ransomware resilience, and recovery — from the BackupSec team.
The classic 3-2-1 rule grew two digits for a reason. Here is what the extra 1 and 0 buy you.

Why 3-2-1-1-0 remains a strong operational baseline — and why modern backup security requires an architectural layer around it.
A Sysdig-documented campaign shows an LLM agent running a ransomware attack chain with no step-by-step human direction, self-correcting failures in 31 seconds. What that compression means for backup architecture.
Immutability, isolation, and tested recovery are the three pillars that keep backups useful when ransomware hits.
For the third year running, unpatched vulnerabilities are ransomware's top root cause (32% in 2025). Why prevention can't close the gap — and what does.
Sophos found the average ransomware victim had 2.7 contributing failures. Why single-control defense is dead and backup is the compensating control.
Backup recovery use fell from 73% to 53% in Sophos's 2025 ransomware report — a four-year low. Why backup confidence is now the metric that matters.
