Setting a value when no backend supports it fails silently

It appears this behaviour is tested. However, I believe that if you set a value, and later get it, you'd expect the same value back.

I also feel that setting a value is confusing at the moment. If you fire up the rails console and set a value, it’s not clear which backend will receive the value, and as such it is not clear if it will be persisted to the next restart or not.

Perhaps setting values should not be possible through the regular shortcut, and it should require the backend to be specified?

I think that would be sane, yes.
