Case Study: China National Offshore Oil Corporation (CNOOC) achieves scalable, efficient local backup and remote disaster recovery with NexentaStor (Nexenta)

NexentaStor Delivers Local Backup and Remote Disaster Recovery Solutions

China National Offshore Oil Corporation’s research institute, which stores massive volumes of offshore exploration and design data across multiple Chinese sites, needed a scalable, cost‑effective backup and disaster recovery solution. Requirements included transparent multi‑tier local backup and long‑distance recovery across heterogeneous, multi‑vendor platforms, petabyte‑scale capacity, RPOs from hours to days, RTOs of one to five days, efficient data migration, and minimal bandwidth use.

After PoC testing, CNOOC deployed NexentaStor on a Dell platform using a unified SAN+NAS two‑tier local backup and two remote disaster‑recovery centers for cross‑site replication and application‑level access. NexentaStor’s AutoTier, incremental transfer, inline deduplication/compression and self‑healing delivered high‑performance migration, reduced bandwidth and storage footprint, flexible replication policies, and effectively unlimited scalability—meeting the institute’s recovery windows, improving data availability, and enabling real‑time verification and reuse of historical data.
