KVM Live VM Snapshots

[Asai]

Greetings,

Is it correct that currently there is no support in Cloudstack for KVM 
live VM snapshots? I see that Volume snapshots are available for running 
VMs, but that makes me wonder what everyone is doing to get a disaster 
recovery backup of a KVM based VM?  I did ask this question a few weeks 
back, but only one person responded with one solution, and I am really 
trying to figure out what the best solutions are here.

Has anybody seen this script?

What is the community's opinion of scripts like this?  And also, big 
question, if this script is good, why isn't it integrated into Cloudstack?

Thanks,
Asai
