Security and Data Recovery

As I move more information online, what information do I need to encrypt? to back-up?

During intervals of the night, when anxiety had kept him waking, the same idea had occurred to him; concealment was his only security[.] 1

Currently, my personal files are backed up to an unencrypted hard drive and, if public, hosted redundantly on github.

Security Goals

Personal Documents

Having worked at a refugee resettlement agency, I believe the following documents should be redundantly (and securely) stored online. Maybe also on optical disk?

Backups

Privacy

I need to save my passwords in a keyring. I’d also like to create a PGP key to share. See riseup.net.

To make strong passwords, I might learn a bit about Shannon Entropy. See pthree.

From Scott Aaronson:

I was reading an obituary of Shannon, 
asking myself: 
why did it take till 1948?
That the semantics of a message 
are irrelevant to how to transmit it, 
that the distribution from which the message was 
chosen is all that matters, 
is obvious.
