LVM & NFS storage and backup


Aug 31, 2018
Hi all.
I'm still a newbie of Proxmox.
In any case I created a cluster with 3 nodes (for HA), two of which are connected via FC to an array of disk with HP MSA2040 controller. This storage is of course set as LVM (it seems to me the only way I can use with Proxmox).
Now I want to add another storage wia NFS so I can get a system where I can backup my VMs created into LVM storage. My question is: which kind of backup can I create on the NFS partition?
At this URL:
it is reported that there are 3 types of backup:
a) Stop b) Suspend c) Snapshot modes
Can I use any of them or the snapshot is impossible because the original VMs cannot be formatted in qcow2 on LVM storage?

TIA in advance for any help.
