A disaster can be anything that puts an organization's operations at risk, from a cyberattack to equipment failures to natural disasters. The goal with DR is for a business to continue operating as close to normal as possible. The disaster recovery process includes planning and testing, and may involve a separate physical site for restoring operations.
Recovery point objective (RPO) and recovery time objective (RTO) are two important measurements in disaster recovery and downtime.
RPO is the maximum age of files that an organization must recover from backup storage for normal operations to resume after a disaster. The recovery point objective determines the minimum frequency of backups. For example, if an organization has an RPO of four hours, the system must back up at least every four hours.
RTO is the maximum amount of time, following a disaster, for an organization to recover files from backup storage and resume normal operations. In other words, the recovery time objective is the maximum amount of downtime an organization can handle. If an organization has an RTO of two hours, it cannot be down for longer than that.
The RPO and RTO help administrators choose optimal disaster recovery strategies, technologies and procedures.
Organizations that house their own data centers must have a DR strategy that considers all the IT infrastructure within the data center as well as the physical facility. Backup to a failover site at a secondary data center or a colocation facility is often a large part of the plan (see "Disaster recovery sites" below). IT and business leaders should also document and make alternative arrangements for a wide range of facilities-related components including power systems, heating and cooling, fire safety and physical security.
Network connectivity is essential for internal and external communication, data sharing and application access during a disaster. A network DR strategy must provide a plan for restoring network services, especially in terms of access to backup sites and data.
Virtualization enables DR by allowing organizations to replicate workloads in an alternate location or the cloud. The benefits of virtual DR include flexibility, ease of implementation, efficiency and speed. Virtualized workloads have a small IT footprint, replication can be done frequently, and failover can be initiated quickly. Several data protection vendors offer virtual backup and DR as a product.
The widespread acceptance of cloud services allows organizations that traditionally used an alternate location for DR to be hosted in the cloud. Cloud DR goes beyond simple backup to the cloud. It requires an IT team to set up automatic failover of workloads to a public cloud platform in the event of a disruption.
