The "two backups" rule address issue #1, yea, I know, even double
redundancy will fail eventually. Life is risk.

As for item #2, I actually take care of that. By compressing and
encrypting PRIOR to uploading to the cloud, there's no way any interested
party can see your data without your password in a reasonable amount of
time given the current level of computing power.
