I have a habit of backing up everything. When I first installed Drupal, I made the 'mistake' of setting various configurations in the administrator settings to keep records of just about everything.
I went into MySQL today to make a backup of the database. I noticed that several tables are getting quite large. Namely: 'accesslog', 'cache', and 'watchdog'.
I searched the Drupal forums for an hour. However, I couldn't find an answer to my problem. I'm still in the process of learning how to administer Drupal and also MySQL.
So, my question is, how can I 'clear' these database tables (caches) without breaking anything?
