Software-only Protection at Any Scale
Simple, scalable data protection with an easy-to-deploy, low footprint, software-only architecture
Architecture Guide for Zerto
Zerto brings together disaster recovery, ransomware resilience and multi-cloud mobility into a single, scalable, software-only solution delivered across on-premises, hybrid, and multi-cloud environments.
Zerto Components
Zerto combines resilience, mobility and protection into a single, scalable, software-only solution.
Zerto consists of five main components that allow you to easily protect, recover, detect, recover and move applications at any scale.

The Zerto Managers
Other than the actual replication of data, Zerto Manager operates everything needed for replication between the protected and recovery sites.
It interacts with the underlying platform and orchestrates recovery, monitors changes, and collects information on entities available for protection within that environment.
In virtualized environments, this manager is called a Zerto Virtual Manager (ZVM), while in containerized environments it’s called a Zerto Kubernetes Manager (ZKM).
In public cloud environments, such as Azure and AWS, Zerto uses a cloud instance called a Zerto Cloud Appliance (ZCA) that is similar to the on-premises ZVM.

Virtual Replication Appliances
A virtual replication appliance (VRA) is a purpose-built software appliance installed on the hosts where virtual or Kubernetes applications will be protected, delivering a true scale-out architecture.
This appliance continuously replicates the data from protected entities to its local and/or remote target, where it then stores the data in the journal.
This same scale-out appliance also copies data from the journal to immutable repositories for additional resilience.
In public cloud environments, Zerto scales replication using a cloud-native scale-out architecture.

Protection Groups
Zerto’s protection, recovery, and mobility are all configured through virtual protection groups (VPGs).
Today, an application is rarely run on a single server or container. Instead, most applications have multiple VM or microservice dependencies. Using the traditional method of protecting individual components results in significant challenges to recovering your complete application.
Zerto VPGs differ by allowing you to group one or more components together into a single entity, ensuring every point in time inserted into Zerto’s journal (a checkpoint) is from the same point in time for all components within the protection group. This allows easy recovery of an entire application and its dependencies to a consistent point in time.

Journals
In addition to VPGs, Zerto’s VRAs store all protected data in the 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. This ensures your recovery point objective (RPO) is always as low as possible, typically a mere 5 to 15 seconds rather than minutes or hours, like most alternatives.

Immutable Offsite Repositories
Along with preparing flexible options for journal-based rapid recovery scenarios, most organizations have a strategy to combat ransomware.
Using Zerto’s extended journal, you can lock copies of your data away in an immutable format, either locally or in the cloud, for up to one year. These additional immutable data copies give your organization the ultimate protection in a worst case scenario.
Zerto Reference Architectures
WHAT OUR CLIENTS SAY
“The most valuable feature of Zerto is its overall flexibility, where it can be used for standard DR or you can also use it for server migrations, data center consolidations, etc… It is kind of a swiss-army knife.”
Mark McCully, Manager Infrastructure, Vizient, Inc.
WHAT OUR CLIENTS SAY
“It [Zerto] just works, regardless of the hardware and software platforms.”
IT Manager, Infrastructure and Operations, Retail industry
WHAT OUR CLIENTS SAY
” I’ve been doing this for over 20 years and sometimes you get jaded by the fact that people over-promise and under-deliver. Zerto was definitely on the opposite end of that spectrum.”
Dan Turner, CIO, PerMar Security Services
WHAT OUR CLIENTS SAY
“Don’t just take ‘No’ for an answer from senior management. The application is phenomenal. They continually add new things, more plugins, and modifications to the way things work. It just gets better as they go.”
Don Cargill, Senior Server Storage Engineer, MAPFRE Insurance
