Yes I have and it's no less horrifying then thinking you can access your cloud server when you suddenly cannot. My point is for a small amount you could afford to buy microsd cards in bulk and backup every day. Or even CD-R/DVD-R/BR-R. But I was trying to keep the discussion to direct transfer from a cellphone as per the parent.

A relatively hassle-free, alternative local backup solution makes sense! Does it exist? For being realistically useful, it should work either over w-fi, or over cable when attached to a computer.

Yes as I already described amd you chose to ignore. Pick your choice or backup program that asks what drive and select your sd card. They are also available with wifi dongles.
