Backup and Restore Databases in MySQL

In MySQL server administration, it is important to safeguard your data in case of human error or a system failure. To accomplish this, MySQL provides the ability to create backups of databases and tables. In this lab, you will be tasked with creating backups for individual databases and tables, as well as full backups of the MySQL server. You will also need to demonstrate the ability to restore the MySQL server from a complete backup.
