How may I encrypt my iCloud backups?

I thought my iCloud data was encrypted. But according to an article I saw in Reuters, “ Apple Inc dropped plans to let iPhone users fully encrypt backups of their devices in the company’s iCloud service after the FBI complained that the move would harm investigations, six sources familiar with the matter told Reuters.” From the rest of the article, it appears my iCloud backups are no longer encrypted. How may I create encrypted backups or store information on the iCloud safe from prying eyes?
