<div id="style_14612437060000000998_BODY">Hi,<br>
I haven't used nova backup yet, I only tested cinder backup. But <br>
obviously you launched that instance via boot-from-volume, so your <br>
instance's image resides within a volume, and volumes are handled by <br>
cinder. So these instances should be backed up via cinder.<br>
