Zerto Virtual Replication: CoreDR

Disaster Recovery by Zerto is the fastest solution available on the market today.

This IaaS disaster recovery solution is geared toward companies who want to balance their recovery time and their costs. CoreDR allows VMware customers to use a hypervisor-based replication solution.

Zerto Virtual Replication (ZVR) is the only out-of-the-box solution that delivers a complete Disaster Recovery Service Management Platform. Centrally managed in one interface, it provides all the technical capabilities including aggressive service levels, and a robust replication solution. Streamline business requirements with
centralized management and automated usage reporting.

Zerto has developed a software-based platform for workload mobility, migration, protection and recovery in hybrid-cloud environments, allowing for seamless flexibility and manageability of applications whether they reside on-premise or in our virtual private data center.



Customers can leverage cloud-based DR to ensure mission-critical applications will be available in the event of an outage, planned or unplanned. IT can now focus on other projects to grow the business, instead of maintaining the business. Companies can choose DR-as-a-Service (DRaaS), protecting on-premise applications to the cloud, and/or In-Cloud DR, protecting applications deployed in the cloud and replicated to a secondary cloud data center.

Virtacore can help you create, implement and maintain your disaster recovery plan.

For information how you can achieve 15 second RTOs in you Disaster Recovery Plan, watch this short video or read the article below:

Is your company’s recovery time objective (or RTO) rendering your disaster recovery plan useless? Don’t fret – there’s a solution. I’m here to share a new disaster recovery option available through Virtacore that will cut your RTO down from hours to seconds.

First we’ll talk about traditional asynchronous replication, then new technology that allows for near synchronous replication. If you haven’t updated your disaster recovery plan in a couple of years, you’re probably using asynchronous replication.

The process for asynchronous replication involves files from image back-ups taken daily at the production site being replicated across the wire to a disaster recovery site. This is called asynchronous replication because it happens asynchronously; it’s not in real time.

Typically, asynchronous replication would be set to occur on a schedule to send file backups over the wire in bulk a couple of times per day.

Between those times, however, data is accumulating yet the disaster recovery site still only has the data from the last time an update was sent. So if the last backup happened at 10am and the system goes down at 5pm, you’ve lost seven hours of data. Yikes! That doesn’t sound very helpful.

Now let’s look at new technology by Zerto, that is offered as a part of Virtacore’s disaster recovery solutions. In contrast to traditional asynchronous disaster recovery options, this new solution by Zerto replicates data nearly synchronously. How do we do it?

An ESXi server cluster is installed at the production site along with one Zerto Virtual Manager (ZVM) and a Virtual Replication Appliance (VRA) for each host.

All newly produced data is routed to the ESXi cluster to be written to the hosts there.

As it enters the cluster, however, the ZVM and VRAs intercept it and send a copy to the disaster recovery site so that the data ends up being written to the production site and disaster recovery site hosts in near perfect synch.

This new disaster recovery solution changes RTOs from hours to seconds.

Let’s recap. Most traditional disaster recovery options are asynchronous but new technology is now available that allows for near synchronous replication. So if losing hours worth of data in a disaster is problematic for your company, it’s time to update your system.

Thanks for watching. I’m Stephanie McGuinn from Virtacore, a leading cloud services provider specializing in disaster recovery using Zerto’s near synchronous replication.

So this real-time replication of data allows for much tighter RTOs than have ever been achieved with any other disaster recovery product on the market. It’s the difference of hours or at best case minutes between the production data and the disaster recovery data to seconds. 15 second RTOS are very achievable with Zerto.

Imagine losing your production site and you’re 12 hours behind when you gain access to your system again. When disaster occurs the last thing you need to be doing is playing catch up that’s why these RTOs can truly make a difference in your business.

So that’s it. Thanks for watching. If you’d like to learn more visit our website at Virtacore.com or drop us a line at sales@virtacore.com and someone will be right in touch with you.
