A fork of the AutoMySQLBackup script from http:https://sourceforge.net/projects/automysqlbackup/

There is no error checking on the install script.
Run it multiple times and it will overwrite files that are there.

Includes a plist for automatic execution under launchd. So, obviously this is osx specific.

Setup a mysql backup user:

Grant privileges SHOW DATABASES, SELECT, LOCK TABLES, RELOAD on *.* to 'backup'@'localhost' identified by 'someawesomepassword';

Run the installer, it will ask for sudo password

Installs into

/usr/local/bin/automysqlbackup.sh
/usr/local/etc/automysqlbackup/automysqlbackup.conf

Adjust settings in automysqlbackup.conf

Start the launchd plist running:

sudo launchctl load /Library/LaunchDaemons/com.sologroup.automysqlbackup.plist

launchd plist is runs daily at 11:50pm

Update the mysql-post script to set permissions on the databases, less permissive
Add an un-install script
Adjust the PATH var in conf file to what the system has mysql: macports, binary, from source, etc. Try to find the solution for the information_schema issue, possible taking out the --opt for mysqldump
