Wanna know what to store your data on if you want to keep it available?
A USB stick.
There are impressive tales of them surviving, well, pretty much anything.
So here's one more.
A leopard seal ate one. And pooped it out. The poop (you can call it scat if you don't like poop) was collected and then frozen for more than a year. It was then defrosted and rinsed under a tap to get the big bits out. One of the big bits was the USB stick. It was dried out for a couple of weeks, and they still accessed a bunch of photos.
(If you've been hanging out around New Zealand beaches with a blue kayak, you might want to look at the photos ...)
Perhaps all this was just a stress-test of the storage device's ability to ensure the availability of the data --- too bad it didn't provide confidentiality...
They found out who took the pictures and lost the USB stick.
It was the person who collected the poop sample ...
There are more weirdnesses in heaven and earth, than are dreamt of in your statistical measurements, Horatio ...
