What is AutoMySQLBackup?

AutoMySQLBackup is a shell script that helps to take an incremental backup of databases daily, weekly, and monthly. MySQL usually provides a command-line utility for exporting databases as raw SQL, named ‘mysqldump.’ Instead of running this utility manually, you can install AutoMySQLBackup script on your system to automatically run this utility everyday on all your databases. This script depends upon the ‘mysqldump’ command that comes with the mysql-client package. This script backs up the databases at the interval you have set to compressed tarballs. If you want, you can copy these tarballs to other media and encrypt them. Please note that during the time of creating the backup, the script locks the databases. The required time to complete the script execution can vary from a few seconds to minutes based on the size of the databases.
