Question How to extract the MySQL dump of Docker based DB from and old server backup?

[anatol]

Server operating system version

Ubuntu 20.04.6 LTS

Plesk version and microupdate number

Plesk Obsidian 18.0.63

I'm trying to restore an old version of a MySQL 5.7.27 database that was running in Docker, but I don't have a database dump file. However, I do have access to an old full server backup in Plesk Backup Manager.
My questions are:

1. Is it possible to extract the database dump from the full server backup files?
2. If not, can I extract the Docker-mapped files for the database, which were located at /var/docker/mysql_docker?
3. What's the best approach to restore this database using the available backup?

As I know, plesk backup system not backup docker images from 2016 there is open case for this: Backup manager: Include Docker containers

So if you have only backup from backup manager you cant get your databases from docker container, you need access to server and get backups from docker directly.

And how about files from /var/docker/mysql_docker, does Plesk include them in backup?
