Best Free Online Tool of the Month - Dropbox.com

The best free online tool is Dropbox.com. You can drop your files into the dropbox folder on your desktop and they get uploaded to your online storage space at Dropbox.com. Then you can open your laptop at the cafe and get access to the latest versions of your files by accessing them at your account at Dropbox.com.

You can back up your database files using the Backup Migrate module and by adding a patch, you can also store them at Dropbox.com for other team members to access. See http://tombigel.com/2010/09/19/dropbox_support_drupal_backup/
