You use WordPress? You want to make backups of your database? You’re tired of the old-fashioned way of backing it up? Skippy.net now offers the WP Database Backup Plugin. You can download the backup or have it e-mailed.
Also, suitable for non-WP driven sites as well, Maratz offers his free Backup2Mail script (not a WP plugin), which also sents the backup to your inbox.
I’ve now set up my database backup, which is sent to a separate Gmail account. Plenty of room for it there.
