A volume provides storage which is not destroyed when a VM is terminated. On Compute Canada clouds, volumes use [https://en.wikipedia.org/wiki/Ceph_(software) Ceph] storage with a 3-fold replication factor to provide safety against hardware failure. More documentation about OpenStack volumes can be found [https://docs.openstack.org/cinder/latest/cli/cli-manage-volumes.html here]. | A volume provides storage which is not destroyed when a VM is terminated.

Creating an image from a volume allows you to download the image. Do this if you want to save it as a backup, or to spin up a VM somewhere other than the CC Cloud, e.g. with [https://www.virtualbox.org/ VirtualBox]. If you want to copy a volume to a new volume within the same cloud see [[#Cloning a Volume|cloning a volume]] instead. To create an image of a volume it must first be detached from a VM. If it is a root volume, it can only be detached from a VM if the VM is terminated/deleted. | Creating an image from a volume allows you to download the image.
