You can download the graphical MySQL management gui tool and schedule backup jobs. You can run it on a different computer that has a GUI. Either Linux or Windows.
The MySQL Administrator's Guide lists three methods for backups.
1) mysqldump --tab-/path/to/some/dir --opt db_name
2) mysqlhostcopy db_name /path/to/some/dir
3) Copying the *.frm, *MYD and *.MYI files (but not for InnoDB tables)
Consider buying the MySQL Administrator's Guide book. It lists other files you should backup in case of an emergency.
Also download the Manual from the website. It contains information about security that you must read.
The "man 5 crontab" man page contains an example crontab. This is the file read by cron that tells it what and when to run. For SE Linux, you will need to read Red Hats documentation. For MLS mode, you need to do more. The man 5 crontab manpage has a paragraph on SE Linux, including the commands, and a sample crontab.
