The best prevention is not letting it happen in the first place.

Ya think?! We’re past that.

Completely unnecessary for you to preemptively assume someone would choose a “crappy” backup from a retail store when in fact such a backup would still likely have saved the day, and any half-decent dev should at least have some kind of RAID backup on site and better yet an offsite one too.

The flaw was not having any backup, not your straw man of a poor quality choice.
