Which backup strategy will minimize downtime (fastest recovery) after a failure?

The correct answer is C. Regular full backups. A full backup contains a complete copy of all data at a point in time, so recovery requires restoring only one backup set - minimizing RTO (Recovery Time Objective). Incremental backups (A) require restoring the last full backup plus every subsequent incremental, multiplying…

Explanation

A full backup contains a complete copy of all data at a point in time, so recovery requires restoring only one backup set - minimizing RTO (Recovery Time Objective). Incremental backups (A) require restoring the last full backup plus every subsequent incremental, multiplying restoration time. Differential backups (B) require the last full backup plus the most recent differential, which is faster than incremental but still slower than a standalone full. 'No backups / disk snapshot' (D) is contradictory as stated and unreliable in a failure scenario. For fastest recovery, full backups win despite their higher storage cost.
