Building Blocks

Zerto’s disaster recovery solution works using innovative Hypervisor-Based Replication technology which is made up of the following two components:

Zerto Virtual Manager (ZVM) – this manages disaster recovery and business continuity at a site level and is plugged into VMware, vCenter and/or Microsoft System Center Virtual Machine Manager.

Virtual Replication Appliance (VRA) – this continuously replicates the virtual machines and associated virtual disks. One VRA is installed per ESXi/Hyper-V host. VRA software is automatically deployed on physical hosts.

Benefits of Hypervisor-based Replication

  • Fast RTO (under 15 minutes) and an RPO of seconds.
  • Installed inside the virtual machine which means that VRA is able to tap into a VM’s IO stream. This means whenever the VM writes to its virtual disks, this is also captured, cloned and sent to the recovery site.
  • Allows you to recover down to an individual machine by being able to replicate at the correct level of any virtual entity.
  • Zerto simply resides in the hypervisor enabling easy centralised management from the virtual machine console.
  • The hypervisor replication is software based so it can be deployed and managed easily for complete control over your scalability.
  • Hardware agnostic, supported on all storage arrays.

Automated Failover and Failback

With Zerto the failover process can be done quickly in just 4 simple steps:

Once the recovery plan has been put in place it means that failover and failback can be carried out in just a few clicks. You also have the ability to roll back the failover once the disaster recovery is underway should you need to e.g. if there are any potential issues at the recovery site.

Testing made easy

Many companies are required to demonstrate the effectiveness of their disaster recovery processes in order to pass audits. In the past this has meant performing these demonstrations outside of work hours in case any disruptions were caused to users. With Zerto you can carry out failover testing in a matter of minutes at any time with specially created sandbox testing within a safe test environment. And it’s not a complicated process either as you can carry out testing with just a few clicks of the mouse!

Data Recovery

Users deleting files or folders accidentally is still the most common disaster that IT managers need to address. Zerto Virtual Replication allows this process to be as painless as possible by providing the ability to recover a single file or folder up to 14 days in the past.

With the data replicated to the disaster recovery site it is easy to create an offsite of data for long-term retention should you need it for compliance.
