Hey,
Working on a new Wordpress site that needs a back up after every change to the site, big or small. So I guess I should back up the WP database too? I've never done that before - does a WP database backup just save posts and comments? Is there any other purpose to it? This site doesn't have a blog so just wondering if the database backup is necessary?
Cheers

Just to affirm the good advice already posted.
Yes 100% you should take your own backups of your WordPress database. It's holds not only your page content but all the other settings - even your WordPress username and password.
The database does not contain the contents of your WordPress Media Library so our advice to our users is to use the backup tool in their Ecenica control panel to take a full backup of their account. This is very easy to do if your host offers cPanel.
If you just want to backup your database we recommend the WP-DBManager plugin (we use it ourselves).
I also came across
WP Remote this week. It's a 3rd-party service that offers to backup your WordPress website for free (at least for now). Not sure how secure it is though so use at your own risk
Cheers,
