In this article, learn how to implement disaster recovery for on-premises VMware or Azure VMware Solution-based virtual machines (VMs). The solution in this article uses Zerto disaster recovery. Instances of Zerto are deployed at both the protected and the recovery sites.
Zerto is a disaster recovery solution designed to minimize downtime of VMs should a disaster occur. Zerto's platform is built on the foundation of Continuous Data Protection (CDP) that enables minimal or close to no data loss. The platform provides the level of protection wanted for many business-critical and mission-critical enterprise applications. Zerto also automates and orchestrates failover and failback to ensure minimal downtime in a disaster. Overall, Zerto simplifies management through automation and ensures fast and highly predictable recovery times.
| Component | Description |
|---|---|
| Zerto Virtual Manager Appliance (ZVMA) | ZVMA is a management appliance that runs on a secure Linux operating system. The ZVMA enables Day 0 and Day 2 disaster recovery configuration. For example, configuring primary and disaster recovery sites, protecting VMs, recovering VMs, and so on. However, it doesn't handle the replication data of the protected customer Virtual Machines. |
| Virtual Replication appliance (vRA) | Linux VM to handle data replication from the source to the replication target. One instance of vRA is installed per ESXi host, delivering a true scale architecture that grows and shrinks along with the private cloud's hosts. The vRA manages data replication to and from protected VMs to its local or remote target, storing the data in the journal. |
| Zerto ESXi host driver | Installed on each VMware ESXi host configured for Zerto disaster recovery. The host driver intercepts a vSphere VM's IO and sends the replication data to the chosen vRA for that host. The vRA is then responsible for replicating the VM's data to one or more disaster recovery targets. |
| Zerto Cloud Appliance (ZCA) | Windows VM only used when Zerto is used to recover vSphere VMs as Azure Native IaaS VMs. The ZCA is composed of:
|
| Virtual Protection Group (VPG) | Logical group of VMs created on the ZVM. Zerto allows configuring disaster recovery, Backup, and Mobility policies on a VPG. This mechanism enables a consistent set of policies to be applied to a group of VMs. |

You can use Zerto with Azure VMware Solution for the following three scenarios.
หมายเหตุ
For Azure NetApp Files (ANFs), Azure VMware Solution supports Network File System (NFS) datastores as a persistent storage option. You can create NFS datastores with Azure NetApp Files volumes and attach them to clusters of your choice. You can also create virtual machines (VMs) for optimal cost and performance. To use ANF datastores, select them as a Recovery Datastore in the Zerto VPG wizard when creating or editing a VPG.

In this scenario, the primary site is an on-premises vSphere-based environment. The disaster recovery site is an Azure VMware Solution private cloud.
In this scenario, the primary site is an Azure VMware Solution private cloud in one Azure Region. The disaster recovery site is an Azure VMware Solution private cloud in a different Azure Region.
In this scenario, the primary site is an Azure VMware Solution private cloud in one Azure Region. Azure Blobs and Azure VMs (Hyper-V based) are used in times of Disaster.
Azure VMware Solution private cloud deployed as a secondary region.
VPN or ExpressRoute connectivity between on-premises and Azure VMware Solution.
Azure VMware Solution private cloud must be deployed in the primary and secondary regions.
Connectivity, like ExpressRoute Global Reach, between the source and target Azure VMware Solution private cloud.
Network connectivity, ExpressRoute based, from Azure VMware Solution to the virtual network used for disaster recovery.
