I use
Amazon's S3 Service. I am able to do all my backups for my design work and also provide links for freebies and links for my CT. I love it - its very reasonable priced and you only pay for what you use! Its seriously the best investment I have ever made. Because I no longer worry that I'm going to lose my files and everything gets backed up and safe! You should really check it out! You do have to have additional software and I have found
BucketExplorer to be amazing!
