Not what your asking but, I have a backup hard disk at my workplace. I have the same size disk at home and when I need to update something on my backup, I copy it to the at home disk. I bring that to work and bring back the other disk home. This way, there is always a backup away from home. All encrypted so nobody can steal the data.

Other options can be a friend or family member.

And for other stuff I also have it on Google Drive.

I like nextdns.io

Something like torrents. Split the whole thing in small 5gb torrents.

What is reddit? Never heard of it.
