Report across all resources and restore operations.

Meet internal audits and compliance requirements.

Zerto’s Components

ZVM: Zerto Virtual Manager

ZVM manages everything needed for the replication between the production and recovery sites, except for the actual replication of data.

VRA: Virtual Replication Manager

This appliance manages the replication of data from protected entities to its local and/or remote target where it stores the data in the journal.

PGs: Protection Groups

PGS allow consistent recovery of an entire application, and all its dependencies, to a consistent point in time.

Zerto Journal

The journal stores all changes for a user-defined period, up to 30 days, and allows you to recover to any point in time within that journal.

Reference Architectures

Example 1: Disaster Recovery

The disaster reference architecture depicted in the figure on the right shows a set of proven practices for setting Zerto up where a single remote target is being used as the recovery site.


Protected VMs are grouped in VPGs with consistency across all the VMs within each VPG. 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 recommend journal history period for this journal is 8 days as this will cover most recovery scenarios. All changes on the protected VMs are then kept for 8 days before being promoted to the remote replica disk(s).

Architecture Reference

Example 2: Local Continuous Backup 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 as well as a long-term retention repository.


The local journal provides a continuous backup capability, allowing the recovery of files, VMs or applications locally.

The long-term retention repository helps to store the data beyond the journal history for compliance needs.
