What Does Virtual Disaster Recovery Mean?
Virtual disaster recovery is a combination of storage and server virtualization that helps to create more effective means of disaster recovery and backup. It is now popular in many enterprise systems because of the many ways that it helps to mitigate risk.
Techopedia Explains Virtual Disaster Recovery
The general idea of virtual disaster recovery is that combining server and storage virtualization allows companies to store backups in places that are not tied to their own physical location. This protects data and systems from fires, floods and other types of natural disasters, as well as other emergencies. Many vendor systems feature redundant design with availability zones, so that if data in one zone is compromised, another zone can keep backups alive.
