Immutability stops deletion; an air gap adds isolation an attacker on the production network cannot cross. Together they form the last line of defense that 2026 ransomware is built to breach.
What an Air Gap Is
An air-gapped backup is physically or logically isolated from the production environment, so it is unreachable during an attack.
Why It Matters Now
Modern attacks target the recovery path as deliberately as production. An isolated copy an attacker cannot reach removes their leverage.
Implementing It Well
Practical air gap backup veeam uses offline media and isolated, immutable repositories delivered as a validated build, so the isolation is engineered rather than improvised.
Isolation Plus Immutability
The two reinforce each other: isolation keeps attackers away from the copy, immutability protects it even if isolation is somehow breached.
Recovery Confidence
The purpose is a clean recovery source after an attack reaches everything else.
