Cloud server volumes

We provide the Cloud Server Volumes service as an additional storage option to the Cloud Servers service of ours. The service allows for the persistent storage of data on volumes that can be attached to cloud servers as block storage devices. A physical hard drive is an example of a traditional block device; you can think of a block storage device as of a physical hard drive or USB stick, but more reliable.

You can create a new volume using a simple one-page wizard in the "Cloud Servers > Volumes" section of the Customer Portal. You can also use the OpenStack API to create volumes.

You can restore a backup of a volume as a new volume using the volume creation wizard.
