i understand that when we talk about transport mode it is related to the proxy.
i read on a blog that using hotadd improves the processing rate and is better than nbd transport.
to get optimal performance, whats the best architecture:
1 veeam physical backup server + 1 veeamPROXY VM on the ESXi
only 1 veeam backup server VM which also act as proxy on the ESXi
here is a doc from vmware which talks about the hotadd.
The following has been quoted from this link:
Also advise on the quoted text.Limitation with Mismatched Block Size
HotAdd cannot be used if the VMFS block size of the datastore containing the virtual machine folder for the target virtual machine does not match the VMFS block size of the datastore containing the proxy virtual machine. For example, if you back up virtual disk on a datastore with 1MB blocks, the proxy must also be on a datastore with 1MB blocks.
