[pve-devel] KVM Live Backup performance

[Dietmar Maurer]

> Repeated same test but used LVM snapshot and vmtar:
> lvcreate -L33000M -s -n test-snapshot /dev/vmdisks/vm-108-disk-2
> /usr/lib/qemu-server/vmtar  '/etc/pve/qemu-server/108.conf'
> 'qemu-server.conf' '/dev/vmdisks/test-snapshot' 'vm-disk'|lzop -o
> /backup1/dump/backup.tar.lzop

you need to mount the snapshot, then backup the VM image instead.
