Zerto Virtual Replication Components
Zerto Virtual Replication comprises the following components:
Zerto Cloud Manager (ZCM) – A Windows service that enables managing all VMware sites offering disaster recovery either as a service (DRaaS) or completely within the cloud environment, protecting one site and recovering to a second site (ICDR).
As can be seen in the above diagram, each site has a Zerto Virtual Manager installed, and one Zerto Cloud Manager manages all the sites.
Zerto Virtual Manager (ZVM) – A Windows service that manages the replication between the protection and recovery sites. A ZVM that is directly managed by a ZCM must be a VMware vCenter Server or vCloud Director site. DRaaS sites managed by the ZVM can be either VMware vCenter Server or Microsoft SCVMM sites.
Virtual Replication Appliance (VRA) – A virtual machine installed on each ESX/ESXi host that hosts virtual machines to be protected or recovered, to manage the replication of data from protected virtual machines to the recovery site.
Virtual Backup Appliance (VBA) – A VBA is a Windows service that manages back-ups within Zerto Virtual Replication. The VBA service runs on the same machine as the Zerto Virtual Manager service and is responsible for the repositories where offsite backups are stored. These repositories can be local or on a shared network.
Zerto User Interface – Recovery using Zerto Virtual Replication is managed in a browser.
Zerto Self-service Portal (ZSSP) – An out-of-the-box DR portal solution with a fully functioning browser-based service portal to enable cloud service providers to quickly introduce disaster recovery as part of their portal offering.
The following diagram shows the basic architecture for sites with Zerto Virtual Replication deployed. These sites are then managed by the Zerto Cloud Manager.
