Looks like your storage/network is overloaded. Try reducing the vzdump bandwith (see 'man vzdump').
Also post the output of 'pveperf' from your Proxmox VE host and give details about the used storage/raid hardware (Proxmox VE host and Openfiler).

Subject: [PVE-User] VM issue when Backup over NAS,
Openfiler : 2.99
NAS LAN : 1GB (through put is 25% i don't know why, at least acceptable)
Proxmox : 1.8
Quadcore : 2.66
Ram : 8GB
Proxmox LAN : 1G
I am using Openfiler as a NAS box. and using NFS and ISCSI both as a storage medium. but i have noticed one thing when i backup a VM on NFS and also copy a huge file inside Running VM which is hosted on ISCSI on same openfiler box. My VM get stuck. i can move the copy window in running VM but can not close task bar or copy window. until the backup task of a VM gets finishes then copy inside VM continue and VM gets usable.
how can i over come that issue. for instance if i run backup backup of my data which is inside VM it will again HANG and thing may unavailable to users during backup which is not an option
