[Leica] Backup hardware: USB3 HDD

[Mark Rabiner]

People on these LUG backup conversations seldom mention the idea that as
long as your backups are not too far apart if one of them turns out to be
corrupted you've still got the one before that so its not like you've lost
everything.  You've only lost your more current stuff. And if you've double
backed up then you've not even lost that.
I'm just saying the world doesn't end if every drive you've ever backed up
to does not last forever. As you know that's not going to happen anyway and
it doesn't have to.
