One trick I use is copy my back-up file (encrypted) to my cell phone's
micro-SD.. In the event disaster struck, I would either be out of the
house with my cell phone, or grab a few belongings including said mobile
before I rushed outside. The problem with that is that it still has the
original vfat .. formatting, and whatever it is, it doesn't like 4G+
files either :-)

I guess that addresses my original question in good part.. I already
have a large enough collection of coasters, thank you.

Apart from the cost of the medium... I am very suspicious of all the
hidden stuff that infects anything Blu-Ray.. And you're probably right..
may turn out to be unsuitable for data archiving.

Same here.. That's one of the reason I'm not in too much of a rush to
revamp my current backup procedures.
