Final answer:
Regular backups are a risk mitigation strategy in project management, reducing the impact of potential hard drive failures.
Step-by-step explanation:
The strategy that involves creating backups as a way to resume work quickly after a hard drive failure is known as mitigation. The backup strategy doesn't prevent the risk of hard drive failures but instead reduces the impact of such an event by ensuring that the work can be recovered. This aligns with the concept of asymmetric risk, where the consequence of not preparing for a low-probability event could be catastrophic, while the cost of preparing is relatively minor.
