- Use Raid10 (4+ disks). Avoid Raid5 for these reasons: 
- Configure LVM on top of it on the host and configure it on the pve 
storage web panel
- Make simple scripts like this one to create and backup snapshots (even 
on mounted nfs):


# destination backup path (even NFS or other network fs mounted)

# LVM Volume Group path

# we want to be sure that all the LV's are up and available
/sbin/vgchange -ay

#backup vm 101 disk 1
/sbin/lvcreate -L4G -s -n backup-101-1 ${LVMCLUSTER}/vm-101-disk-1
/bin/dd bs=65536 if=${LVMCLUSTER}/backup-101-1 | gzip > 
/sbin/lvremove -f ${LVMCLUSTER}/backup-101-1
