Disaster Recovery as-a-Service (DRaaS) is a cloud-based service that provides organizations with a reliable and cost-effective solution for disaster recovery. Unlike traditional on-premises solutions, which can be complex and expensive to maintain, DRaaS leverages the global public cloud to offer built-in automation, flexibility, and ease of use. This allows organizations to protect their critical applications without the need for extensive hardware investments or labor-intensive maintenance.

When determining the right RTO for your applications, consider the business impact of downtime for each application. Revenue-generating applications typically require shorter RTOs, often in minutes, while less critical applications, like HR systems, may tolerate longer downtimes of several hours. Categorizing applications based on their RTO needs helps prioritize protection efforts and manage costs effectively.

Non-disruptive DR testing is crucial because it allows organizations to validate their disaster recovery plans without impacting ongoing operations. Regular testing, ideally at least once per quarter, ensures that the DR plan remains effective as applications and environments change over time. This proactive approach helps organizations stay prepared for actual disaster scenarios and maintain compliance with regulatory requirements.
