Case Study: CoStar achieves 97% backup success and 10x SQL deduplication with Commvault

$1.66B Real Estate Leader Sees 10X SQL Dedupe, 75% Gain in Backup Success

CoStar Group, a Washington, D.C.–based leader in real estate data and analytics with nearly 5,000 employees and $1.66B in revenue, faced unreliable, fragmented backups across three legacy products — averaging just 55% success — that consumed four to six hours daily, offered poor vendor support, and imposed a 24-hour RTO.

By consolidating to Commvault Complete Data Protection with Commvault Professional Services, CoStar achieved a 97% backup success rate (a 75% improvement), 5x global deduplication and 10x on SQL (reducing 11.2 PB to 2 PB on disk), and cut daily backup management to one hour or less. Recovery times dropped to one hour for disk and under four hours for tape, tape storage fell 9x, and the IT team shifted from firefighting to higher-value architectural work.
