Does a service exist that compresses your entire Google Account (GDrive/Docs/Gmail/etc.) to an archive and then uploads it to your Dropbox (or other cloud storage) account? I don't want to ditch using Google, I'm too integrated, but I would like to back up everything to a second source just in case.
