Disaster Recovery (DR) is a security insurance strategy that protects a datacenter from the effects of a natural or man-made catastrophe. In the event of a disaster, a DR plan ensures a business can either quickly resume operations or maintain mission-critical functions during or after a disaster, depending on the severity of the event.
To better understand DR, we also must define a disaster in the technology industry. A disaster, in the most simple terms, is anything that puts an organization's operations at risk. This can be a cyberattack, a data breach, an equipment failure, a natural disaster, or even rats chewing through cables. Not to mention, any of the following can create an IT disaster:
- Data loss
- Human error
- Malware and viruses
- Network and internet blips
- Hardware and/or software failure
- Weather catastrophes
- Natural or pipe burst flooding
- Office vandalism or damage
When a disaster strikes, the goal of any DR plan is to ensure operations run as normal as possible. While the business will be aware of the crisis, its customers and end-users should not be affected whatsoever. The disaster recovery process includes planning and testing, and may involve a separate physical site for restoring operations.
Many businesses also opt for a disaster recovery as a service (DRaaS) strategy, a model that lets you duplicate and host servers in a separate datacenter through a third-party provider. Some cloud vendors offer a native DRaaS solution, which simplifies the installation process. Businesses rely on the third-party vendor to not be affected by the same disaster, and the moment a disaster strikes the original business, the third-party vendor will initiate a DR plan when the enterprise cannot.
