It is not the best way, it is error-prone, a live guest system consists of more than what is found on the virtual disk. As Etienne Goyer mentioned this approach will most likely fail (to recover) when guests contains running databases. Expecting LVM snapshots to be sufficient for making a backup of a running guest is like expecting powering of the machine (the hard way) will not rsult in data-loss. Because in both situations, data on disk is all what you have. You will lose disk-writes that has not been synced yet, and of course the machine state (which may be less important) I will not hope inCharge uses this method for taking backup of customers virtual machines. Unfortunately there is no email. I would have notified Julian about this problem.
