I have a Proxmox version 3.3 hosting a test XP VM on a DS1513+ NAS iSCSI LUN. When I perform a backup of my VM to the local drive of the Proxmox or to an NFS share on a different HD in the same NAS it runs at about 10MB/s. I also have an identical XP VM on the local drive of the Proxmox and when I back it up locally it has an average speed of 572MB/s. I have edited the /etc/vzdump.conf to bwlimit: 900000
What am I missing?
