Assumptions

• mysql binary logging is enabled
• default mysql storage path: /var/lib/mysql
• mariadb mysqldump and mysqlbinlog will work the same as actual mysql. Please let me know if this is a bad assumption.

TODO:

• ability to use different mysql bin log file name
• ability to use different path to mysql bin log
• ability to create separate cron job for daily and hourly
