Cohesity NetBackup vs Commvault Air Gap Protect: Side-by-Side Comparison (2026)

Short answer

Enterprise and mid-market teams managing hybrid cloud infrastructure will get the most from Cohesity NetBackup because its immutability enforcement and automated malware detection actually prevent ransomware from corrupting backups at scale, which is where most recovery plans fail. The platform covers the full NIST RC recovery cycle,from incident mitigation through coordinated restoration,and includes native Kubernetes backup with hash-based IOC search that catches threats other backup tools miss. Skip this if your team is primarily on-premises with minimal cloud footprint; the hybrid orchestration features justify the complexity cost only when you're juggling AWS, Azure, and GCP simultaneously. Mid-market and enterprise teams defending against ransomware need Air Gap Protect's physical separation of backups from production networks, which turns recovery from an assumption into a guarantee when primary systems are encrypted. The three-tier storage architecture with immutable Retention Lock policies and zero-trust access controls directly addresses NIST PR.DS and PR.IR, the two functions most often compromised in ransomware incidents. Skip this if your organization hasn't experienced a breach or lives in a regulatory environment where air-gapped backup isn't mandatory; the operational overhead and cost of maintaining isolated storage isn't justified for teams still building basic backup hygiene.
