Longhorn Backup and Disaster Recovery

I want to protect Kubernetes application data and need to understand how Longhorn backups and disaster recovery workflows operate.

The platform supports snapshots and backup targets, so I need clarification about how data is stored and restored after failures.

I also need troubleshooting help for failed backups, incomplete snapshots, and restore operations that do not complete successfully.

My organization requires off cluster backups, so I want examples showing how Longhorn integrates with S3 compatible storage systems.

I need guidance for creating automated backup policies that protect persistent volumes without affecting application availability.

I also want to understand how Longhorn handles recovery when a node or entire Kubernetes cluster becomes unavailable.
