Persistent VMs
Persistent VMs are designed to boot from volumes (see booting from a volume) thus creating a copy of the volume(s) the VM has attached to it will produce a backup. However this would not preserve things like VM flavor, public IP, and security rules. The best way to create a copy of a volume for backup purposes is to create an image from that volume. An image can be downloaded and reused to create multiple new VMs, can be accessed by VirtualBox on your desktop or laptop, and uploaded to other clouds.
