#“Automatically Backup Your WordPress Site to Dropbox”
A new plugin is available that gives you the opportunity to put Dropbox to work for the security of your WordPress site. Heres how you can set up automatic backups of your WordPress site to Dropbox:
via wpmu.org
Superb idea if you aren't already doing it to Amazon S3 or similar.
Particularly good if the whole area of backups seems like a black art to you. Dropbox will give you 2GB free without a credit card. Do it.
