I am trying to understand "Object Lifecycle Management" in https://cloud.google.com/storage/docs/lifecycle
The concept of "live object" appears to be central to the subject, but it is not defined. What is a "live object" exactly?
("live data" has a different meaning in https://en.wikipedia.org/wiki/Backup#Live_data)
A live object is one that is not an archived generation. If you enable versioning on a bucket, deleting or overwriting an object leaves an archived generation. Lifecycle Management gives you the option to operate only archived (or only live) generations.
