There’s a few things webby that most people forget or don’t know how to do. My line of work has brought these up again and again, and accordingly, I’ve found a few bits to help save the day.
Lester Chan’s WP-DBManager is grand. One-click to backup your db to your email. Hopefully it’s cron-ready- we’ll find out next week ;).
Another random gem logs incoming user-agents & auto-blocks IP addresses. TTC WordPress Security Tool is handy for stopping scraping and general meany-stuff. The author has a few more bits, especially for when you require users to create accounts.
