title: How to schedule a cron job to backup a MySql database every week?
body: <p>What is a command line I can use to back up a MySql database every single week into a file name with the date (so that it doesn't collide with previous backups)?</p>
  
  <p>Also, is this a reasonable backup strategy?  My database is relatively small (a complete export is only 3.2 megs right now).  The churn rate is relatively low.  I need to be able to get the complete DB back if something goes wrong.  And it would be extra cool if there's a way that I could see the changes that occur across a time span.</p>
