KVH Strengthens Ransomware Protection, Cuts Backup Time by Over 70% with Cohesity

Kassenärztliche Vereinigung Hessen (KVH) is the public healthcare body that manages billing and services for panel doctors in the German state of Hessen. As data volumes grew (surpassing 300 TB) KVH faced slow backups and restores (backups took seven hours; finding a lost file often 45+ minutes), scalability limits from MBR-partitioned file servers, strict GDPR and patient-data retention requirements (10 years), and an urgent need for stronger ransomware protection.

KVH replaced its legacy stack with Cohesity — deploying primary and DR clusters plus a separate immutable vault, and moving file services to Cohesity SmartFiles with built-in ClamAV. The result: consolidated backup, file services, and ransomware protection; 31% faster VMware backups, restores typically started in under five minutes (vs. 45+), Instant Recovery for VMs, 5:1 data reduction and 49.2x storage reduction, immutable offsite copies for ransomware defense, and simpler single-vendor management.
