Ask HN: What do you use to back up mobile photos and videos straight to the cloud?

I take a lot of photos and videos with my phone that I want to save for years to come. And of course as a result I run out of space on my phone. I'm looking for a solution that backs these up straight to the cloud, without having to copy them on my laptop. So far i have used Dropbox's automatic camera upload & paying $80/year for 1TB of storage that should last me a good while. However, this product has been discontinued. What service do you use or recommend to backup your camera in a convenient and reliable way?
