Understanding business continuity and disaster recovery for NPSaaS

IBM® Netezza® Performance Server for IBM Cloud Pak® for Data as a Service service gets deployed in a single zone. When a zone goes down, NPSaaS service is brought online into another zone by a recovery strategy.

Disaster recovery strategy

NPSaaS uses the cloud storage snapshot technology to provide support for business continuity and disaster recovery. A snapshot is taken every day at 2 AM. Snapshots are available across three cloud zones within the same geographical region to ensure availability if a single zone fails.

The Netezza Performance Server snapshot feature currently backs up only the data stored in block storage. Data stored in object storage is not included in snapshot backups.

If a zone failure occurs, the disaster recovery process is automatically triggered. The service quickly starts in one of the remaining zones with the latest available snapshot.
