SugarSync isn’t merely a back-up solution; you can sync all your files such as Microsoft Office documents, photos, music, and media to all your computers and web-enabled mobile phones, instantly. Store and back-up your files in their secure servers and access them from any web browser, anywhere, anytime. Share files with your friends, family, and colleagues. You can even stream music live.
All SugarSync subscriptions start with a 30-day free trial (credit card required). The customer chooses their subscription plan and payment frequency (monthly or annual) when they register for a free trial. At the end of the 30 days, the account will automatically convert into an auto-renewal paid plan. Of course, you cancel your account anytime in the 30-day free trial period to stop this.
If you don't need much storage, you can get a free 5 GB account. It's free online backup, free file sync, and free file sharing. No credit card required, no monthly payments. No kidding, it's free.
