Hello,

Currently I have a NFS ubuntu storage holding my VM's. I have about 89 vm's and during my testing I did not test the backup. As I just did a back up I checked the log and noticed that it is suspending the VM during this. I looked at the http://pve.proxmox.com/wiki/Storage_Model and some other post and it seems that you only get live snapshots with lvm2.

so, do i have to have lvm2 installed? I just want to be 100% as I assumed that the live snapshot would have happened with the NFS storage server as well ( no LVM on it ). I need to know as I need to explain that to the team that this is not feasable on our current setup. As I am also spec'ing out new cluster hardware wich lookes like I will need to have iscsi capabilites to go with the :LVM Groups with Network Backing"
 
online backups with LVM snapshots does not work if you got your VM disks on NFS.

it works if you use local storage (the default setup if you install from ISO), LVM on iSCSI/FC/Local disks/DRBD/...
