Files that I might want to keep for many years (e.g., music mp3s) are
stored in multiple places. And the music is all from my own CD
collection, that I encoded myself with cdparanoia and lame.

Ditto for straight rsync. And the first time I ran the command it took
well under ten minutes. Subsequently the command takes five seconds or
so. And it's going to run at 3am anyway.

The fire will probably burn me up as well. As for thefts and other
calamities, I'll take the risk. When I recently switched insurance
companies the new agent was aghast that I wanted a $10,000
deductible. I insisted. Life is full of risks.

I just want a nightly mirror so I can restore a file that I
accidentally deleted. And I want to keep it as simple as possible. And
I want it to be something that I can understand. I'm not running a
Fortune 500 company here. If I lose everything no one is going to lose
their job; no stockholders are going to be wiped out. I'm not really
that important, you know.
