Zerto Virtual Replication provides a business continuity (BC) and disaster recovery (DR) solution in a virtual environment, enabling the replication of mission-critical applications and data as quickly as possible, with minimal data loss. When devising a recovery plan, these two objectives, minimum time to recover and maximum data to recover, are assigned target values: the recovery time objective (RTO) and the recovery point objective (RPO). Zerto Virtual Replication enables a virtual-aware recovery with low values for both the RTO and RPO. In addition, Zerto Virtual Replication enables protecting virtual machines for extended, longer term recovery from an offsite backup.

Zerto Virtual Manager (ZVM) – A Windows service that manages the replication at the site level. The ZVM monitors the vCenter Server to get the inventory of VMs, disks, networks, hosts, etc. For example, a VMware vMotion operation of a protected VM from one host to another is monitored by the ZVM and the protection and recovery is updated accordingly. Each Zerto Virtual Manager can manage up to 5000 virtual machines, either being protected or recovered to that site.

OVF to enable installing Virtual Replication Appliances (VRAs) – 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. A VRA can manage a maximum of 1500 volumes, whether these are volumes being protected or recovered.

Virtual Backup Appliance (VBA) – 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 manages 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 or in the VMware Web Client or Client console.
