When it comes to business continuity for virtual machines (VMs), Zerto replication technology gives businesses scalable and customizable solutions.


Zerto Replication in a Nutshell

From television to e-mails, books, and banking – day by day, our environments are becoming increasingly virtualized. This is especially true in the business world, where companies are making the switch from physical servers to virtual machines.

Zerto caters to virtualized infrastructures, providing enterprise-level data replication that sets companies up for high availability (HA) solutions and effective business continuity. With Zerto replication technology, your company’s data is replicated within seconds, giving you the lowest possible recovery point objective (RPO) and recovery time objective (RTO).

Zerto software is specifically engineered for virtualized data centers and cloud environments, giving cutting-edge technology exactly what it needs to stand up to today’s 24/7/365 business environment.


Key Benefits

  • Security
  • Flexibility
  • Scalability
  • Customizability
  • Eliminated downtime



First and foremost, Zerto allows VM replication to the target of your choice. Data that is replicated from your production site is encrypted and monitored to ensure that it arrives securely at your failover site.

This real-time replication keeps your company’s data secure from the downtime and data loss following a disaster by ensuring that your business seamlessly keeps going through failover to your target server.



Zerto replication allows you to replicate what you need, when you need it. Companies can choose between recovery of one, all, or just a subset of virtualized applications. In other words, you can recover more than just data; you can group whichever VMs you choose so you can consistently replicate and restore entire applications when you need them.

This can also be done at multiple sites, so that all branches of a corporation are protected. Plus, if your provider has expertise in layer 2 communications, you can take advantage of partial failover solutions in the event that only one critical server or application goes offline.



Zerto is a scalable solution, usable by companies of any size regardless of growth.

Companies are constantly acquiring new customers and new data, and their replication solution needs to be able to keep pace with these changes. Because Zerto is software-based it can be deployed and managed easily, and you don’t need to purchase, install, or configure any additional hardware.



Data replication frequency can be customized to your exact specifications; if you want your data replicated within seconds (compared to minutes), then the target site will have the most recent version of your data which it can use to take over in case of a disaster.

Zerto is also array agnostic, meaning that it can replicate from any storage source to any storage destination. This allows for customized HA, clustering, and the ability to locate and replicate volumes in motion. Plus, you can choose and group which VMs to replicate and restore, allowing for revival of entire applications of your choice in the order you need them.


Eliminated downtime

Possibly the most appealing aspect of Zerto replication technology is that it virtually eliminates planned and unplanned downtime for VMs through its integration with HA solutions.

If the production site goes offline, you can switch over to the backup server with your most recently replicated data and seamlessly run production from there. This keeps your business-critical applications and servers running 24/7/365.

Most of the replication process is automated, ensuring that it occurs simply and unobtrusively. To top it off, installing Zerto only takes minutes, with no downtime and no need to make any changes to your storage or server infrastructure.


Partnered For Best Results

Zerto provides replication coupled with recovery tools to automate your recovery and failover solutions. By partnering your Zerto replication solution with high availability, your systems become truly resilient to both planned and unplanned downtime. When your disaster (or human error, hardware failure, security breach – you name it) is resolved and your production site goes back online, your servers will also synchronize so you can switch back to the production site as if nothing happened.

That’s why we use Zerto technology to ensure that your business maximizes uptime and minimizes downtime, no matter what.
