If I built a NAS with a Raspberry Pi thing, it would be small enough
that I could just add a handle to it. Then I could bring it in the
house, do backups and such and then store it in a out building away from
the house. If I had a climate controlled outbuilding, I could either
run a ethernet cable or use wireless to do backups. Of course, all this
costs money as does anything I need to do. :/
I did check the price of a Raspberry Pi thingy a couple weeks ago.
About $150 to $200 would likely get it off to a good start. It's not bad
really but that is a chunk of change. I was actually looking into that
to run my VPN thing on. Still thinking on that.
