“Evermore is a simple WordPress plugin that automatically abbreviates all posts on a multiple-post page such as the blog home page. It has the same effect as putting the ‘more’ tag after the first paragraph of every post.”

This is a plug-n-play plugin to backup your WordPress database. It can e-mail the backup to you or offer it as a download (or just store it on the server). And, it supports scheduled backups as well.
