Case Study: DenizBank achieves 50% OPEX reduction and 8x faster backup and restore with Commvault

DenizBank cuts OPEX by 50% and increases agility with Commvault

DenizBank, a top‑ten Turkish bank serving about 40 million online customers across 2,170 branches, faced scaling challenges as mobile use generated roughly 1.3 million transactions per day and five petabytes of backup data. Its legacy mix of backup targets and slow VM replication could not meet required backup/restore performance, complicated storage and cloud migrations, and made meeting evolving data‑privacy and regulatory requirements difficult.

By consolidating onto Commvault Complete Backup & Recovery with Commvault HyperScale Software and adding Commvault Activate plus email archiving, Intertech (DenizBank’s IT arm) simplified operations and sped migrations to VMware and Azure. The bank achieved an 8x improvement in backup/restore speeds, cut OPEX by 50%, reduced a 4 TB restore from eight hours to under one, moved 15 VMs to DR sites in under 30 minutes, and strengthened data governance and compliance search.
