Case Study: Piraeus Bank secures Microsoft 365 data and reduces data-protection costs by 30% with Veeam

Veeam protects Microsoft 365 data for Piraeus Bank’s 12,000 users

Piraeus Bank, a leading Greek bank supporting millions of customers, needed to secure Microsoft 365 data for about 12,000 users after its prior backup solution couldn’t provide on‑premises protection. Because SharePoint, Teams and Exchange underpin critical banking processes and customer communications, the bank required on‑prem control, long‑term retention for legal compliance and reliable recovery during a migration to Exchange Online.

Working with Infinitum, Piraeus Bank deployed Veeam Backup for Microsoft 365 with an on‑prem S3 object repository (HPE Apollo Nodes with Scality Artesca) in a hybrid configuration. The solution delivered fast, granular recovery (industry‑leading RPOs), simplified eDiscovery, met security and regulatory requirements (including long‑term retention) and cut the total cost of ownership for data protection by 30%.
