Air Gap Backup with Veeam in 2026: Building the Last Line of Defense
Immutability stops an attacker from deleting a backup, but an air gap adds a second, complementary defense: isolation that an attacker on the production network cannot cross at all. Together they form the last line of defense that 2026 ransomware is specifically engineered to breach, and understanding how they reinforce each other is essential to building recovery that survives a full compromise. An air gap is not a relic of tape-era thinking; it is a modern, deliberate layer that keeps a clean recovery source beyond an attacker's reach. Why an Air Gap Matters Now Modern ransomware targets the recovery path as deliberately as it targets production, because destroying the backups is what forces a ransom. An air gap defeats this by keeping at least one copy physically or logically isolated, so an attacker with full access to the production network still cannot reach it. In a threat landscape where backups are a primary target, isolation that an attacker simply cannot cross is one of ...
