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 everything required for the replication between the protected site and Azure, except for the actual replication of data. Each Zerto Virtual Manager can manage up to 5000 virtual machines, either being protected or recovered to that site.

Virtual Replication Appliance (VRA) – A Windows service that manages the replication of data from protected virtual machines to Azure. A Virtual Replication Appliance can manage a maximum of 500 volumes.

Virtual Backup Appliance (VBA) – A Windows service that manages back-ups within Zerto Virtual Replication 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 by the Zerto User Interface in a web browser.
