If you're syncing the image then I'd be interested to know how you do that if Xen is the host. Can you run rsync on Xen? I thought it was just a hypervisor. Or can Dom0 access the images of other guests to rsync them? If you are just syncing files in the guest (which I wouldn't protest about) then the methods are not really comparable because the essential point of my approach is that the whole bootable image is backed up, which is desirable to some people for lots of reasons.
