Always-On Replication
At the core of Zerto is always-on replication, the engine delivering continuous data protection and industry-leading disaster recovery
How Does Zerto Replication Work?
Learn more about how Zerto's flexible software-only, scale-out architecture can help you protect applications while minimizing data loss.
How It All Started
In 2011, Zerto introduced hypervisor-based replication to the world. By moving replication up the stack from the storage layer and into the hypervisor, Zerto created the first and only solution that delivers enterprise-class, always-on replication for disaster recovery (DR) and migrations on private, public, or public clouds.
Why Replicate Within the Hypervisor?
Unlike some data protection solutions that use cumbersome snapshots and agents, Zerto provides continuous replication with zero impact on application performance recovery.
Hypervisor-based replication natively integrates with all supported platforms, meaning it is hardware agnostic and not dependent on the underlying storage arrays. It also supports the full breadth of capabilities made possible by virtualization, including high availability, clustering, vMotions, etc.

What is Hypervisor-Based Replication?
How Zerto Replication Works
The following components reside at the heart of Zerto platform’s replication technology:
Zerto Virtual Manager (ZVM)
The management server integrates with vCenter and has an intuitive interface that orchestrates user-initiated operations with simplicity.
Zerto Cloud Appliance (ZCA)
In public clouds, the ZVM is replaced by a ZCA for cloud management. It integrates natively, using cost-efficient storage offerings, APIs, and cloud scaling features.
Virtual Replication Appliance (VRA)
Our scale-out replication appliance with built-in WAN optimization, encryption, and quality of service (QoS), replicates every change generated to the target journal—the true workhorse of continuous data protection.
VRAs, whether on-premises or in the cloud, copy every data write after the underlying storage acknowledges it. A VRA on the source site then sends this copy to a VRA on the target site before committing the I/O to the journal in the order that it was generated to ensure write-order fidelity. As the journal fills, it then commits the oldest recovery points to the replica disk.

Zerto Near-Synchronous Replication for Lowest RPOs and RTOs
Zerto’s software-only approach achieves replication benefits nearly identical to those found in expensive hardware-based synchronous replication solutions— but with RTOs of minutes and RPOs of seconds. On top of that, software-based asynchronous replication is much cheaper and more practical than its hardware counterpart—and it’s easier to deploy and support.

Enable Cross-Platform Replication
With automatic, on-the-fly conversion of VMs, you no longer need to match platforms between your datacenters. This allows you to use the platform of your choice—depending on your workload, cost, performance, and availability—without being locked in by technical limitations. Easily protect to or from the cloud without worrying about the underlying infrastructure layers.
One-to-Many Multi-Site Replication
Zerto’s innovative one-to-many feature allows a VM to simultaneously replicate to several target platforms—including VMware vSphere, Azure, AWS, VMware on public cloud, or over 350 managed service providers—while also replicating locally or to a second remote site.

FEATURED SUCCESS STORY
Leveraging Zerto's One-to-Many Replication
For years, Canadian Blood Services had been protecting all its VMware-based applications with Zerto. So when the organization heard Zerto had a multisite replication tool, it conducted a proff of concept and started its datacenter migration journey without hesitation.
WHAT OUR CLIENTS SAY
"Zerto has dramatically improved our IT resilience to keep data running and replicated across all our locations, and ensures we can recover data and keep IT running to support Tyler’s public safety and public works in the event of a disaster."
Benny Yazdanpanahi, CIO, City of Tyler
WHAT OUR CLIENTS SAY
"Zerto's replication is superior to anyone else's out there. It's faster, simpler, and effective. I don't think I could get as low an RTO and RPO with any other solution other than Zerto."
Chief Information Officer, SmartBank
WHAT OUR CLIENTS SAY
" It is a very cool product that integrates easily with an existing virtualization platform and makes cross platform migrations a breeze! "
Virtualization Engineer, Company in Services Industry
WHAT OUR CLIENTS SAY
"We had always trusted Zerto with our critical VMware apps and workloads, so its one-to-many replication really clinched the deal with us,” ... “With this feature, we can simultaneously replicate our VMs to both new sites, enabling us to test our workloads in both locations before migrating them to their designated home datacenter for operational use."
