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