Protecting Virtual Machines to and From vCloud Director : Replication From a Protected Site vCloud Director to Azure
  
Replication From a Protected Site vCloud Director to Azure
You can protect a VCD vApp to Microsoft Azure.
When creating a VPG from vCloud Director to Azure the data is stored in a storage account and all replicated data from protected virtual machines to Azure is encrypted in the storage account. All recovery operations bring up the recovered machines in resource groups in Azure.
■ Only virtual machines that are supported by Azure can be protected by Zerto Virtual Replication. All Windows operating systems are supported.
Note: Microsoft does not support operating systems that are past the End of Support date, without a Custom Support Agreement (CSA). For more information about Microsoft operating systems support for Microsoft Azure, refer to https://support.microsoft.com/en-us/kb/2721672.
■ For Linux distribution, refer to Azure documentation:
■ Linux on Azure-endorsed distributions: https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-linux-endorsed-distributions/
■ Information for non-endorsed distributions: https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-linux-create-upload-vhd-generic/
■ Protected volumes are recovered in Azure as VHD disks in a page blob. Virtual machines with disks that are less than 1GB are recovered with disks of 1GB.
Note: For some instance size, the Azure virtual machine is created with a Local SSD disk which is a temporary disk. This disk is in addition to the disks associated with each protected virtual machine.
■ The following limitations apply when protecting to Azure
■ Virtual machines with UEFI Firmware cannot be protected.
■ You cannot protect machines that have a disk larger than 1TB.
■ The protected virtual machines needs to have at least one NIC.
■ The supported number of data disks and NICS per virtual machine is dependent on the selected instance size. For example, instance size D3_v2 allows up to eight data disks per virtual machine.
■ To create a VPG that will be recovered to Azure, you must have a virtual machine in Azure with a Zerto Cloud Appliance installed on it. This ZCA must be paired with the protected site.
For additional considerations, see Azure subscription and service limits, quotas and constraints: https://docs.microsoft.com/en-us/azure/azure-subscription-service-limits.
For example, see the following default values:
■ 20 cores per subscription
■ 200 Storage accounts per subscription
■ 20 VMs per region per subscription
■ VM per series (Dv2, F, etc.) cores per subscription201 per Region
Additionally, see the following example for maximum values:
■ A standard storage account has a maximum total request rate of 20,000 IOPS. The total IOPS across all of your virtual machine disks in a standard storage account should not exceed this limit.
