Zerto provides enterprise-class virtual replication and disaster recovery solutions that maximize uptime & enable a hybrid cloud strategy.
We need to do is install the Zerto Virtual Manager (ZVM) that plugs into your vCenter or System Center depending on if you’re running VMware vSphere or Microsoft Hyper-V. The data is replicated using the scale-out, hypervisor-based Zerto Virtual Replication Appliance (VRA).
These are deployed on each and every hypervisor host that you are replicating from or to. This allows every protected VM to have a local replication appliance no matter where it moves around to within the cluster, and it creates this scale-out architecture meaning Zerto can protect your environment with the same software whether you are a 10-VM environment or have thousands of VMs to protect in your environment.
The VRAs are only replicating the virtual machine block-level changes. It is performing real-time and continuous replication, removing the need for any scheduling. If nothing is changing, nothing is replicating, and as soon as a block changes and is written, it is asynchronously tracked and sent to the recovery site with no snapshots, and no impact. The recovery site contains virtual disks for the replica if the VM data, and journals for the latest changes, up to 30-days back.
We took the concept of placing all the VMs on the same storage LUN in order to achieve data consistency between replicated VMs on that storage, and applied across all storage in your environment. Typically, you would take all the VMs that belong to your enterprise application and place them on the same LUN, snapshot that LUN, replicate it and recover the LUN, and all your VMs will be there from the same point-in-time. Zerto took the replication and moved it into the hypervisor so it’s no longer dependent on the storage replication. With our Virtual Protection Groups, we protect all the VMs together that you add to this VPG, give them all granular checkpoints with write-order-fildelity across the VMs, and allow you to recover them together from the same point-in-time.
Recovery Process: 1. Click Failover, 2. Select, 3. Verify, 4. Start Failover
Zerto is completely integrated with your hypervisor and the key thing I want you to notice here is you can see across all your protected VMs you are shown the real-time RPO. You won’t find another solution that is going to show you this, let alone right when you login to the dashboard. What is your RPO today? Go search through your interfaces and technologies and try to piece together your RPO and exactly how much data you will lose if you were to failover right now. Zerto will give you that real-time RPO across your site, and for each Virtual Protection Group (VPG) as well. It doesn’t matter what your environment is underneath, you get the same interface every time. We also use this same interface to perform and prove out your DR testing, with reports generated and all available right through this dashboard.
