Protecting Virtual Machines from a vCenter Server : Protecting a vApp (Via the VMware Web Client or Client Console)
  
Protecting a vApp (Via the VMware Web Client or Client Console)
You can protect a vApp as a single entity in a VPG for any vApp defined under an ESX/ESXi host. All the virtual machines defined in the vApp VPG are protected and you can migrate or recover the whole vApp as a single entity to the recovery site. The recovery site cannot be Microsoft SCVMM nor Amazon Web Services (AWS).
In addition to being able to protect the vApp, you can protect individual virtual machines in the vApp, in the same way as you protect any other virtual machine. However, if you protect a virtual machine in the vApp, you cannot then protect the vApp as a single entity.
The individual machines in a vApp can be protected using the Zerto User Interface. A vApp can only be protected as a vApp via the vSphere Web Client or Client console.
Note: Nested vApps are not protected. Also, if you drag a protected vApp under another vApp to nest it, the protection is removed. You cannot protect vApps which include virtual machines with VirtualEthernetCardLegacyNetworkBackingInfo NICs or with IDE devices.
To protect a vApp:
1. In the vSphere Web Client or Client console, select the Zerto tab for the vApp to be protected.
If the vApp contains virtual machines that are protected, the tab displays a message that the vApp contains protected VMs and you have to remove the protection from these VMs before continuing to protect the vApp.
Each virtual machine in the vApp can have a maximum of 15 disks per SCSI controller and up to 4 SCSI controllers.
2. Click CREATE VPG.
The Create VPG wizard is displayed. The VPG Name defaults to the name of the vApp and in the VMs step the virtual machines in the vApp are selected. You cannot make any changes in this step.
3. Make any required changes to the VPG, as described in Protecting Virtual Machines to a Recovery Site vCenter Server, starting with step 6.
