Highly available persistent storage for Kubernetes
Longhorn is based on Kubernetes and built for Kubernetes, 100% open source, cloud-native persistent block storage without the cost overhead of open core or proprietary alternatives.
Easy deployment, management, upgrade
Longhorn delivers simplified methods for easy deploy, upgrade, and management.
Builtin snapshots and backups
Longhorn’s built-in incremental snapshot and backup features keep the volume data safe in or out of the Kubernetes cluster.
Cross-cluster disaster recovery
Longhorn can easily create a disaster recovery volume in another Kubernetes cluster and fail over to it in the event of an emergency. If your main cluster fails, you can bring up the app in the DR cluster quickly with a defined RPO and RTO.
CSI compatible storage driver
Longhorn supports complete capabilities of CSI storage driver like volume creation, expansion, cloning, encryption, snapshot, restoring, etc.
Native virtual workload storage backend
Longhorn provides built-in virtual disk image management and volume live-migration to support the integration with virtual workload orchestration solutions like Harvester and KubeVirt.
Microservices for volume lifecycle management
