something comes from the side and messes up your data in a different way than you've foreseen.
This happened to me years ago. Naïvely thinking SnapRAID protected me against the likelihood of a drive failure. I wasn't prepared for two drives failing simultaneously due to a power supply catastrophically failing (smoke, sparks) and frying the drives as it died.
It was an expensive lesson: I had to send one drive off for data recovery, and after I got it back I used SnapRAID to restore the remaining drive. Independent backups (and multiple parity drives) is the way.
I think it was from one of the No-Laughing Batsu game specials, probably before 2014. I'm not sure which one it was though.
