What’s the difference between disaster recovery and backup?
Disaster recovery, on the other hand, refers to the plan and processes for quickly reestablishing access to applications, data, and IT resources after an outage. That plan might involve switching over to a redundant set of servers and storage systems until your primary data center is functional again.
Why do you need a secondary data center for disaster recovery?
That’s why most disaster recovery strategies employ a secondary site that is some distance away from the primary data center. You might locate that other site across town, across the country or across the globe depending on how you decide to balance factors such as performance, regulatory compliance and physical accessibility to the secondary site.
Can a disaster recovery solution be used in the cloud?
Cloud-based backup and disaster recovery solutions can support both on-premises and cloud-based production environments. You might decide, for example, to store only backed up or replicated data in the cloud while keeping your production environment in your own data center.
