I'd like to ask the list, when you backup your data (and you do, don't
you?) - do you use encryption? If so, what measures do you take to
ensure the key is safer than the data itself?
My backups are merely encrypted tarballs of my $HOME directory, with a
password. Like you, I fear not having access to whatever data that I
need to open my backups, but do not want to leave them unencrypted.
How do you use the password in an automated backup then?
You encrypt using a public key. You only need the private key in order
to decrypt.
