At the risk of sounding dumb (which I am) and drifting off topic (which
this does) can you explain what you mean by "protected by air gap".
Our scenario involves a rotating set of USB Disks that are to be
hot-swapped once a day. To me this has seemed like the simplest part of
the backup solution we are designing but is this not the case? Am I
missing a complicated piece when I envision it?
