I'm glad you agree. That was exactly the point I was making. :)

Burglars here are more interested in money, or things that are easily
convertible to cash. Power surges are not at all likely. Fire maybe
could destroy a disk but the chances of such a major fire in our house
is very minimal (I would have fitted a sprinkler system if I thought
there was any likelihood). Hacking a device on the other side of the
Internet is inherently more likely than hacking a device only locally
connected; not visible to the Internet, or even the local network and
mounted only whilst the backup operates. So I'm not terribly concerned.

When I was operating systems professionally, sure my backups were both
local and on other continents and stored on RAID systems. As were the
hot standby operational systems. Horses for courses :)
