Case Study: NTT DATA achieves faster backups, lower costs and two-year retention with Commvault

NTT DATA group protects mission-critical data with Commvault

NTT DATA group, a global systems integrator (including NTT DATA and NTT DATA Intellilink) based in Tokyo, needed to safeguard mission‑critical internal systems on its private cloud. Rising data volumes, lengthening backup windows, past backup failures, and the high cost and operational burden of transporting magnetic tape for long‑term retention created an urgent need to improve backup efficiency and extend retention from three months to two years.

The group deployed Commvault Complete Backup & Recovery, using DASH Full and DASH Copy to replace tape with deduplicated remote network backups. The implementation reduced backup windows by up to 33%, cut backup data size by up to 60% with deduplication rates as high as 90%, eliminated tape transport costs, enabled two‑year retention, and simplified operations while supporting future growth.
