How to take single database backup using mysqlbackup command in Mysql 8.0.18 version DB
If you create the backup using the --tts option, when restoring your instance you can include/exclude selected tables. A whole database is included/excluded by selecting all of its tables with --include/exclude=&quot;^databasename\.&quot;
The MySQL official documentation explains it very well:

Hope it helps.
