Some people may don’t know that it doesn’t matter which cloud provider you will choose, get the cheapest one but reliable. I got Wasabi S3 storage, 1TB/6$ Use rclone to mount into your filesystem, create encrypted mount point and send your files there. Now you have Wasabi(or any rclone supported cloud) and what they see are garbage (encrypted content). Also, since the mounted point is just like a directory, you can use FileRun, NextCloud, whatever. I use Syncthing to sync dirs from Phones and other PC.
