Managing snapshots of an instance in Horizon

View as Markdown

Learn how to manage snapshots from the OpenStack Horizon interface.

During your activity, you will probably need to back up your data, configurations, and even your entire instances. To do this, you can create snapshots of your instances. These can be used to restore a later configuration on your instance or to create an exact copy of an instance.
