Disaster recovery reference architectures
In disaster recovery architectures, resources are usually duplicated and replicated to a different data center and geographical region to ensure that they are far enough away from the source of the disaster.
Skytap supports multiple disaster recovery solutions, depending on your current application location and your business requirements. The solutions include cold and warm off-site disaster recovery for your applications running in your on-premises data center, as well as disaster recovery to an alternate region for applications running in Skytap.

On-premises data center to Skytap – cold recovery
In a cold disaster recovery architecture, the backup location and resources aren’t running in real time. It takes longer for them to come online in the event of a disaster, as they need to be powered on and updated. Usually, data must also be restored from an alternate location or from cold backup.

On-premises data center to Skytap – warm recovery
In a warm disaster recovery architecture, the critical backup resources are running in real time in Skytap, while less critical resources may be suspended and out-of-date. Some data may need to be restored from an alternate location or backup.

Skytap region-to-region – cold recovery
In a cold disaster recovery architecture, the backup location and resources aren’t running in real time. It takes longer for them to come online in the event of a disaster, as they need to be powered on and updated. Usually, data must also be restored from an alternate location or from cold backup.

Skytap region-to-region – warm recovery
In a warm disaster recovery architecture, the critical backup resources are running in real time in a second Skytap region. Less critical resources may be suspended and out-of-date. Some data may need to be restored from an alternate location or backup.
