I want cloud storage in case house burns down.
for such scenario we back up to mutually to eachother with a friend. Pretty easy to do with synology nas, probably with others as well. However, 64TB is a considerable amount of data on its own...
This does not offer the sharing capabilities though, since everything goes there crypted of course.
I wonder if sharing is an critical requirement, as you can do that from your location too, the backup does not need to have such capability.
