A command line tool that backups all MySQL database instances it can find on a MySQL server.

  $ cd mysql-backup
  $ sudo rake install

h2. Configuration

Configuration is easy, just run the built-in mysql_backup_install command:

  $ sudo mysql_backup_install

The installation script will ask you to enter all necessary information and then writes the configuration to /etc/mysql_backup.

  $ sudo mysql_backup

This will backup all databases, except the ones defined in the configuration file using the skip parameter.

Add the following:
