Online File Storage & Backup
DropBox: Dropbox allows you to store up to 2GB of data for free. You can get more space for referring people, or you can buy space (100GB starting at $9.99/month).
Google Drive: You can store the first 5GB for free at Google Drive and then access your files from anywhere. Great if you’re a Google or Google Plus user.
SugarSync: Possibly even better than Dropbox, it gives you up to 5GB for free and allows you to sync all your files from any device.
