I can't do it on my phone though. And that's the device that might change after some time (years). AFAIK, Signal is coded explicitly to disallow backups of the data on iOS. Can't back it up with iTunes backup or on iCloud. I believe security was a reason (sacrificing UX deeply, IMO). I don't use Signal because of its comparatively poorer UX and feature set (the others I consider are Telegram and Wire). And without being able to backup conversations from an existing/old phone and restore them on a new phone, I'll never use it. I learned about this behavior the hard way during a previous switch and lost all my conversations (for some I had the patience to take screenshots).
