VM becomes unresponsive during Backup to NFS

Hi

We have one VM which is quite large over 600GB with alot of small files as it hosts many websites.
Its the only VM which seems to go down whenever a backup to NFS runs for a few minutes each night.

Trying to ensure this does not occur.

I read a few posts on the forum which recommend :

1. Switch to NFS3
2. Switch to CFQ - we currently have it set to deadline as we use hardware raid with raid 10 on our Proxmox nodes.

Backup server is using FreeNAS with Raid-z2 with 6x 2TB sata disks.

Alternatively do you think wiping the server clean and have a standalone glusterfs server would work better ?
