When backing up a custom image, which is based on another. Docker handles this dependency, i.e., exports both?

If you are in need of backup, there is something wrong with Docker’s usage strategy. Unlike a VM, a container is created thinking of its death as something everyday. So what you need is to have a dockerfile that allows you to recreate the image if the image no longer exists. Volatile data, such as upload data, database data etc, should be in volumes.

You really are right. I had not stopped to ponder this question.
