Detailed explanation of How to Backup & Restore the registry

[bradws]

I cannot seem to find anywhere explaining the process of backing-up and restoring (if a failure) of the reigistry data.
The packages uploaded to the registry are valuable, and a backup/restore plan is crucial.
My suggestion would be to include is as documentation on the website for both the regular Verdaccio install, and the Docker image version as well.
We cannot use Verdaccio reliably until we have a backup/restore plan.

Is this possible please?

I attempted to do this with the Docker image, but struggled to get it working as there wasn't much info around.
I would be happy to contribute, however I will need some steps/guidance.

Thank-you.
