How to properly organize a local docker registry launched from a container?

Question

Docker

Good afternoon.
deployed the docker register from the container.
But over time, the question arose with the release of the disk from obsolete images.
According to this, the question is how to properly organize the register from the container in order to:
1. Protect yourself as much as possible from the loss of images
2. Make it easier to clean up the place from obsolete images
If someone has experience, please share.

I searched superficially, but did not find a finished one. You can take curl or any project (for example https://www.google.ru/url?sa=t&source=web&rct=j&ur... ) to manage the docker registry and remove what is considered garbage. Manually or automatically by tags with an outdated version.
To ensure the safety of images with an ordinary backup.
