In their own words
JetStream DR
JetStream DR provides continuous data protection and disaster recovery for VMware workloads. It replicates VM data to object storage, with a stated recovery point objective of near zero, and says it can bring VMs back online within minutes using recovery clusters provisioned on demand. It captures data through VMware vSphere I/O Filters and is managed from a vCenter plug-in or the vSphere Web GUI. Protected VMs do not need installed agents or snapshots, according to the maker. Listed targets include S3-compatible storage such as AWS S3, Azure Blob Storage, Cloudian, and MinIO, as well as Azure NetApp Files. Its hypervisor-level software supports on-premises SAN, NAS, vSAN, and HCI environments, with VMware-compatible recovery infrastructure. Coverage is listed for vSphere 7 and 8, with hybrid deployment, cloud backup targets, and off-site replication. JetStream DR for AVS is obtained through Azure Marketplace; on-premises installations use an OVA from JetStream support. The company describes the product as built for service providers supporting customers’ on-premises continuity needs.
Longhorn
Longhorn is a free, open-source distributed block storage system for Kubernetes. It replicates storage across nodes and data centers to increase availability, with V1 replicated, V2 replicated and V2 sharded with erasure coding volume types. Teams can schedule recurring snapshots and backups to NFS or S3-compatible secondary storage, and create disaster recovery volumes for recovery in a second Kubernetes cluster. A GUI dashboard is included, and the management UI is described as free. The software stack can be upgraded without disrupting running storage volumes. Installation options include kubectl, Helm, Fleet, Flux and ArgoCD. Longhorn supports mTLS for securing and encrypting gRPC communication between its control and data planes, but mTLS is disabled by default. Components need root access with privileged permissions for volume operations and management. Backups require an NFSv4 client, while ReadWriteMany volumes require NFSv4.1. Longhorn runs on Linux and supports API, web and self-hosted use. It is a CNCF incubating project; SUSE Storage is described as a Longhorn-based distribution with additional support, security, lifecycle management and certified integrations.
