Why not? Make encrypted backups with `borg` and use `rclone` to distribute them to a number of free cloud storage services -- this is what I and many others do. One of my destinations is Yandex Disk. They all only see an encrypted Borg repo. And in the next few weeks or months I'll make sure they won't even be seeing that. Just a few opaque files several tens of megabytes big each. I wish them luck cracking it, lol.

What are they going to do, fly to my fringe country, knock on my door and politely ask me to stop storing encrypted blobs on their servers? No, they will not. First, their TOC does not forbid it and second, they are way too lazy to scope me out of the crowd, and third, they will only start shutting users down if their free plan starts costing them too much. I've been doing this for years and nobody seems to give a frak (Google included).

And I am just a regular guy who wants to make sure his code and passion projects (and personal / family photos) are never going to get lost even in a case of disaster. I never in my life did anything to warrant government attention.
