Strategies And Solutions For Business Resilience: Disaster Recovery
Red Hat News, Friday, November 24,2023
Disaster recovery (DR) is the ability to recover and continue business-critical applications from natural or human-created disasters. It is a component of the overall business continuance strategy of any major organization, designed to preserve the continuity of business operations during major adverse events.
Region failure is usually expressed using the terms Recovery Point Objective (RPO) and Recovery Time Objective (RTO).
- RPO is a measure of how frequently you take backups or snapshots of persistent data. In practice, the RPO indicates the amount of data that will be lost or need to be reentered after an outage.
- RTO is the amount of downtime a business can tolerate. The RTO answers the question, 'How long can it take for our system to recover after we are notified of a business disruption?'
There are several possible approaches to disaster recovery. As with everything in life, each option comes with its own set of advantages and disadvantages, and we must carefully choose and adapt the most suitable solution.
