Upgrading to a faster restoration technology would likely result in the most significant reduction in the mean time to recovery (MTTR). Migration or upgrades that offer quicker restore times directly influence the duration of service unavailability by speeding up recovery processes. Although standardizing backup procedures and increasing backup frequency might improve recovery procedures, they do not necessarily decrease the actual time taken to recover services once a disruption has occurred. Hiring additional cloud engineers could help but is not directly related to the technological or procedural aspects that determine recovery speed.
