Using the Cloud for Disaster Recovery
Conclusion: Disaster recovery continues to be an issue for many clients. Approaches based on tape have a low cost benefit but often recovery takes too long to meet the business’ requirements. The popular new approach of replicating data to a secondary data centre enables rapid recovery but at a cost which is prohibitive for some applications or smaller organisations.
An emerging third approach is to use Cloud infrastructure (IaaS) as a warm standby. This is attractive both in terms of cost and recovery time and can also be used as a strategic stepping stone for adopting IaaS.
