If you don't use Linux, iDrive is a good Dropbox alternative in these ways: 1) it lets you sync your files (Dropbox's focus), 2) it lets you backup your files and mobile phone (better than Dropbox), 3) it gives you 5GB on a free account, not just 2GB and 4) it uses end-to-end encryption, which means iDrive employees can't spy on or give away your stuff. And neither could any hackers should they get in.
