Zerto Components
ZVM: Zerto Virtual Manager
ZVM manages everything needed for replication between the production and recovery sites, except for the actual replication of data.
VRA: Virtual Replication Manager
This appliance manages data replication from protected entities to its local and/or remote target where it stores the data in the journal.
VPGs: Virtual Protection Groups
VPGs enable consistent recovery of an entire multi-VM application, and all its dependencies, to the exact same point in time, even if the VMs reside on disparate datastores or hosts.
Zerto Journal
The journal stores all changes for a user-defined period, from one hour up to 30 days. It allows you to recover to any point in time within that journal using recovery points that are only separated by 5-10 seconds.

Reference Architectures
Example: Disaster Recovery
The disaster recovery reference architecture on the right demonstrates proven practices for setting Zerto with a single remote target used as the recovery site.
DESCRIPTION
In a single remote target architecture, protected VMs are organized in protection groups with VM-level consistency. A remote journal is configured on the remote target side and used for short-term recovery scenarios where recovery granularity of just seconds can be achieved. The recommended journal history period for this journal is eight days as this will cover most recovery scenarios, including ransomware. All changes on the protected VMs are then kept for eight days before promotion to the remote replica disk(s).
Architecture Reference
Example 2: Local Continuous Replication and Disaster Recovery
The disaster reference architecture depicted in the figure on the right, takes the previous "disaster recovery" architecture and adds a local journal and an extended journal repository, which uses cost-effective public cloud storage for immutable off-site copies.
DESCRIPTION
The local journal provides a continuous replication capability, allowing the instant recovery of files, VMs or applications locally.
The immutable copy helps to store the data beyond the journal history for compliance needs, and provides a virtual, air-gapped copy immune to ransomware and accidental deletion.
