It doesn't have this feature right now, but I'm currently working on a memory copy-on-write mechanism for Xen that can be used for taking snapshots of VMs (without needing to stop them). Used in combination with a disk snapshotting tool (like Parallax) you could create backups of your VMs. I'll be my initial implementation to this list very soon, in fact.

There are other people working on this sort of thing too (Mike Sun, for example).

Hello everybody,
 My name is Zign and I would like to ask a simple question.
 For example, I want to backup my VMs everyday. But I do not
want them to be stopped while the backup. For this reason, I can't
use a traditional way like:  freeze the VM  -> backup everything ->
restore the VM.
 So is there any solution for this?
