How to export .sql file from Webmin backup file?

I backup my website with Webmin backup function.So i got complete public_html and other files.But i cant see my website .sql file in backup files.Also i seen a some files in .backup folder. but i cant restore my database with COM_MYSQL_MYDBNAME file.What can i do for it?

The DB files are in the .backup folder as ‘domain_dbname.gz’. Should be able to extract and upload them individually from there. Once extracted, they are simple sql text files for each DB that can be used to “run sql from file” in order to restore the db via mysql.
