Current available Backup Strategies
❖ Not integrated in the admin or user view of OpenShift
❖ Runs separately (most often) outside of OpenShift
❖ Might need special precautions for maintaining application data consistency
❖ Configuration and interactions directly on the storage environment

Potential future backup enhancements
❖ Snapshots of Persistent Volumes through Kubernetes
❖ Promotion of snapshots to new Persistent Volumes
❖ Container with backup application binds the Persistent Volume
❖ Opens the road for User-Self-Service to do backup and restores
❖ Can run completely inside OpenShift
