I recently read this article which highlights the following method:</div><a href="http://www.linux-kvm.com/content/first-look-virtual-machine-online-disk-snapshots-coming-fedora-18">http://www.linux-kvm.com/content/first-look-virtual-machine-online-disk-snapshots-coming-fedora-18</a><div><br></div><div>1. virsh snapshot-create-as to create the snapshot</div><div>2. cp myvm.qcow2 myvm-backup.qcow2 to copy off the now read-only backing image file</div><div>3. virsh blockpull to merge the base and snapshot images together into a single image again</div><div><br></div><div>Is this functionality only available in qemu 1.1? I am using Ubuntu 12.04 LTS on production servers which only includes qemu 1.0.x. Is there a safe alternative for accomplishing live backups like this on qemu 1.0.x? Is there a minimum version of libvirt that supports this behavior?</div><div><br></div><div>Thanks,</div><div><br></div><div>Andrew</div></div></body></html>
