This from my backup:
128        ok       00:29:26
17.08GB  /mnt/pve/qnap_nfs/dump/vzdump-qemu-128-2014_10_18-05_31_23.vma.lzo

In generel I see backup speed around 25 MB/s on my relatively slow Qnap.

One question: Do you make backup to the same storage as the VM's reside
on?

If this is the case then I would imagine that speed were halfed.
