Disaster Recovery (DR) refers to the strategies and processes that enable a business to resume operations after a disruption caused by catastrophic events, such as cyberattacks, natural disasters, or pandemics. A robust DR plan not only aims to restart operations but also focuses on minimizing data loss during such events. In today's volatile environment, having a solid DR strategy is essential for maintaining business continuity.

Disaster Recovery as a Service (DRaaS) is a cloud-based model that allows businesses to back up their data and critical IT infrastructure with a third-party provider. This service enables organizations to restore normal operations after a disaster without the need for significant upfront investments in hardware. With the market for DRaaS expected to reach $41 billion by 2025, it offers a flexible and cost-effective solution for many enterprises.

Recovery Point Objective (RPO) is the maximum age of data that must be recovered from a backup to resume normal operations, expressed in time intervals such as seconds or hours. Recovery Time Objective (RTO) is the maximum time allowed to restore operations after an outage. Together, RPO and RTO help organizations determine the frequency of backups and the necessary technologies for effective disaster recovery planning.
