    • Spideroak both syncs AND backs up your files. Dropbox is not a backup service. Most importantly, Spideroak encrypts files on your computer before uploading them to their servers, which means only you can see your files and no one else. Dropbox doesn't do this, which means that Dropbox employees could access your files, which a much less private solution.
