If you have a server such as a Web Server built using Laravel Forge, it only installs PHP and NGINX.
You plan on using a managed database from Digital Ocean and use the server to run
mysqldump for database backup, you will not be able to.
In order to use mysqldump
mysql-client must be installed on the server.
Log into SSH and run
sudo apt update sudo apt install mysql-client
