Disaster Recovery Strategies For A Disaster-Prone World
ITProToday, Friday, February 21st, 2025
Downtime is costly, but a well-planned high availability (HA) and disaster recovery (DR) strategy can minimize disruptions.
High availability (HR) is the ability to shift the operation of an application, workload, or service to another secondary server or servers and quickly resume functioning in the event of a fault, failure, or disaster. Disaster recovery (DR) locates secondary servers geographically distant for protection from sitewide, regional, or cloud availability zone disasters. Efficient, reliable HA/DR is vital for maintaining uptime and continuity of services. That's because the alternative - downtime - is expensive.
