"Either way, paying ransom should never be an option, doing so harms all users by increasing the power of these organizations."
This, 100%.
I recently helped someone dealing with data loss precipitated by a power outage, and their practice of leaving their USB backup drive in the computer caused their backup to fail. However, because they persisted in using paper to maintain double entry accounting they were able to rebuild by re-entering the data.
Where possible, keeping paper copies of keys, addresses, and accounting data is another backup mechanism that is immune to hackers.
Thanks!
