>too easy to either destroy ... their volumes.
As someone who's started running services in Kubernetes (albeit mostly as a hobby thus far) I would recommend setting the ReclaimPolicy to Retain for any PersistentVolumes that are particularly important. The default behavior is to delete the underlying volume when the resource representing it is deleted, but if you're worried that might happen accidentally that may not be what you want; this behavior is configurable.
