Case Study: San Joaquin County achieves 40% backup cost savings, instant restores, and ransomware immutability with Rubrik

San Joaquin County Moves Off of Cohesity to Safeguard Data Immutability and Business Continuity with Rubrik

San Joaquin County, California (population ~750,000) supports critical public services through a central IT team of 90+ that serves 3,000 users. The County’s legacy tape backups — and a failed rollout of Cohesity that couldn’t protect ~40% of data or provide ransomware immutability — left operations vulnerable to data loss, service outages, delayed payments, and threats to law enforcement and public safety.

The County implemented Rubrik to standardize data management, protect over 90% of its environment (including Microsoft and Oracle workloads) and integrate with Azure. The move delivered native immutability against ransomware, cut backup TCO by 40%, reduced restores from around 12 hours to minutes, and freed one full-time IT headcount for strategic initiatives.
