True and in my case I wonder if the problem is my NAS.

Backups to locally attached USB drive are no problem, but I've always had 
problems backing up to my NAS over GB ethernet, using NFS or SMB.

I'd often get 1 or 2 VM's failing with disk write errors, but since I updated 
the firmware on my NAS (shell shock) and started using Kernel 3.10 on proxmox 
nearly all of them are failing.

NAS: QNAP TS-420

Switch: TP-Link TL-SG1024D
  http://www.tp-link.com/en/products/details/?model=TL-SG1024D

Connection is two bonded 1Gb Links.

The nas is also my shared storage.

At this stage, if people think the nas is the p[roblem, I'd be upgrading it.
