Backup, restore, and high availability
The Cloud Pak for Data System architecture mitigates the risk of unplanned downtime or data loss.
Backup and restore
If you have NPS® installed:
- Three control nodes - If a control node fails, the workflow is automatically shifted to another control node.
- Three worker nodes - If all three fail or are unavailable, a control node can become a worker node.
- Two unset nodes - these can also be used if there are failures.
