Zerto Virtual Replication comprises the following components:

Zerto_ArchitectureZerto Virtual Manager (ZVM) – A Windows service, which manages everything required for the replication between the protection and recovery sites, except for the actual replication of data.

Virtual Replication Appliance (VRA) – A virtual machine installed on each ESX/ESXi hosting virtual machines to be protected or recovered, to manage the replication of data from protected virtual machines to the recovery site.

Zerto vSphere Client console plug-in – A plug-in in the vSphere Client console that enables managing recovery using Zerto Virtual Replication from the console.

Zerto GUI – Recovery using Zerto Virtual Replication is managed via a user interface, Zerto DR Management UI, vSphere Client console or vSphere Web Client.
