SugarSync
For Windows and Mac users, SugarSync offers an extensive feature set, including real-time upload, versioning, and full-folder backup. On installation, SugarSync creates a "Magic Briefcase," a folder that automatically syncs to other computers you have with SugarSync installed.
Backed-up files are accessible online and from a wide range of mobile devices, including iPhone, BlackBerry, Windows Mobile, and Android, with the mobile Web site optimized for mobile browsers. Sharing is also robust, with the ability to share files of any size, share folders with permissions and passwords, and initiate direct publishing to Facebook. In addition, the service supports music streaming to Web clients and iPhones.
For individuals, SugarSync offers plans ranging from 30 GB for $4.99 per month to 500 GB for $39.99 per month. Business plans start at 100 GB for three users at $49.99 per month (introductory pricing of $29.99 now available), with additional users costing $9.99 per month per person and additional storage available at $29.99 per 100 GB.
