With this feature, the backing up of VMs using an exclusive physical agent is not really required. It just works with your existing VMware Server. You need to use a proxy VM to process the VMware backups. It can be a new VM or an existing VM from the ESXi server.


For this feature, these are the below requirements from VMware:

The agent must be installed on the Virtual Machine on the same ESXi server where the source VM’s resides. If proxy vm in which backup agent is running is on a VFMS3 datastore, the volume on proxy vm should be formatted with appropriate block size given below depending on the maximum disk size of the source VM(s)

  • 1MB block size – supports up to 256GB
  • 2MB block size – supports up to 512GB
  • 4MB block size – supports up to 1024GB
  • 8MB block size – supports up to 2048GB

The disks that are to be hot added must be SCSI. IDE drives are not compatible with hotadd. The proxy vm should have installed VMware tools and VMware tools should be upgraded immediately to the available newer version deployment.

In order to use VMware UltraBlaze Technology, you’ll need to create a proxy VM and then install Vembu BDR agent on the VM, or you can install Vembu BDR on existing VM. But make sure that the above requirements are satisfied while selecting the VM for Vembu BDR agent installation.
