16 DISASTER RECOVERY GUIDE – Powered by ZERTO SECTION 3 Zerto Virtual Replication When production is virtualized, there is an obvious gap in the data protection strategy as it is usually based on older technologies that have reliance on physical asset limitations. Zerto Virtual Replication aligns production and disaster recovery strategies with a hypervisor-based replication solution. In this section we will explain how the Zerto technology works and the advantages it offers. vCenter SCVMM ZVM ZVM VM VM VRA VM VM VM VRA VM VM VM VRA VM VM VM VRA VM Production Site BC/DR Site VM-Level Replication > 5 Mbps Architecture The heart of Zerto's replication technology is formed by two components: • Zerto Virtual Manager (ZVM) – Zerto Virtual Manager manages disaster recovery, business continuity and offsite backup functionality at the site level; plugs into VMware vCenter and/or Microsoft System Center Virtual Machine Manager, and also includes a browser-based option. • Virtual Replication Appliance (VRA) – Replicates the VMs and associated virtual disks; one VRA is installed per ESXi/Hyper-V host. How replication works? The Zerto Virtual Replication Appliances (VRA) copies I/O as it is created before it leaves the hypervisor. This continuous block-level replication delivers RPOs of seconds, minimizing data loss in the event of an outage. Figure 5. Zerto's Architecture
