I've been using rclone (http://rclone.org/) + AWS CloudDrive form my home backups. Currently storing around 4TB for just 60eur/year. Perfect setup for me personally.
Me too, and I've tried a lot of setups before settling on this. I can download faster from Amazon drive than reading from a USB 2.0 hard drive, and rclone makes it easy to keep important documents in sync on both services as well as locally.
