Unlike storage-based replication, it operates at the virtual machine (VM) disk level (VMDK), enabling granular replication of individual VMs across ESXi hosts, clusters, or even geographically separate vCenter instances.

For environments requiring automated failover, failback, and non‑disruptive DR testing, pair VR with . For simple off‑site copies without orchestration, standalone vSphere Replication suffices. Document version 1.0 – Valid for vSphere 7.x & 8.x esx replication
