Case Study: CityU of Hong Kong achieves 24x7 protection for 5,000+ Microsoft 365 & Google Workspace accounts and cuts restore time to minutes with Druva

CityU of Hong Kong protects 5,000+ Microsoft 365 and Google Workspace accounts with Druva

City University of Hong Kong (CityU), a publicly funded research and professional university with about 25,000 students and 5,000 staff, needed stronger protection for its Microsoft 365 and Google Workspace data. Relying on Microsoft’s native retention (no recoveries older than 90 days) and legacy on‑prem solutions left the university exposed to accidental deletion, ransomware and rising operational costs.

In October 2021 CityU deployed the Druva Data Resiliency Cloud to protect 5,000+ accounts and ~160 TB across Exchange, OneDrive, SharePoint, Teams and Google Workspace. The cloud‑native SaaS eliminates hardware and patching, provides encrypted, isolated backups, and adds self‑service restores that cut email/file recovery from days to minutes while improving visibility, ransomware recovery and cost predictability.
