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.
LINBIT DRBD
LINBIT DRBD is open-source distributed replicated block storage software for Linux, used in high-availability setups. Its kernel driver mirrors writes to one or more peer nodes; in synchronous mode, a write completes only after local and peer storage completion events. Reads can be served locally without network traffic, and the data path avoids user-space components. DRBD combines the kernel driver with user-space management applications and shell scripts, and its command-line interface can manage large clusters without relying on cloud, virtualization, or container platforms. It supports TCP/IP and RDMA/Verbs transports, including InfiniBand, iWARP, and RoCE. The DRBD 9 guide documents TLS encryption for TCP transport. LINBIT also offers WinDRBD for Windows and says its subscriptions integrate with Kubernetes and other major platforms. The open-source community version is free; LINBIT Starter is $1,000 a year, starting from $1,000 for two nodes. The company is headquartered in Vienna, Austria.
