Re: [Xen-devel] Does XEN have any hot backup/snapshot features or plan?

[Patrick Colp <pjcolp@xxxxxxxxx>]

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).
