VDP Backup With External Proxy (via virtuallypeculiar.com)
So in the previous article we saw the types of backup protocol used by VDP. We saw that when the ESXi host which is hosting the VDP appliance does not have the access to the datastore of the VM it is backing up, then the backup protocol used is Network Block Device (NBD). One way to avoid NBD is to bring the VM on to a storage which is seen by the ESXi host hosting the VDP appliance. The other method is to deploy an external proxy for the VDP appliance onto the host which is hosting the client that needs to be backed up. Please note, that once you deploy external proxy, the internal proxy will be disabled automatically.
