Take a look at Drop Box, which offers a free web-based file hosting service.
Drop Box uses cloud storage to enable users to store and share files and folders with others across the Internet using file synchronization. There are both free and paid services, each with varying options. The free service provides 2 GB of free online storage and users who refer Dropbox to others can gain up to 8 GB of additional free storage.
This post is recommending Drop Box as an additional back up option. By placing you latest project files in your Drop Box, you can be sure that your files are safely stored, online, should anything happen to your precious memory stick.
