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).
