Cloud Improves Disaster Recovery and Business Continuity planning
Today’s distributed and dynamic enterprises for disaster recovery need to plan for 24×7 access to a growing set of mission-critical business applications and sensitive data. These applications and data are more distributed than ever: they can reside in corporate datacenters, remote offices, and/or on user computers. In addition, overall data volumes are growing rapidly in every industry segment, and widespread virtualization means that servers and data are more mobile than ever before.
IT operations teams are struggling with flat or shrinking budgets in a tough economy. These combined challenges make disaster recovery (DR) planning more difficult than it has been in the past, but they also make it more important than ever.
In order to meet current demands for application and data availability, successful enterprises are increasingly relying on the Cloud and wide-area network (WAN) as a storage transport resource for DR. This enables DR operations to be centralized—reducing redundancy and lowering overhead—and to leverage innovative disk-based backup and replication technologies offered by the leading storage vendors. Decentralized, tape-based DR strategies are simply too costly and labor-intensive. In practice, they fail to meet the recovery time and recovery point objectives (RTOs/RPOs) demanded by companies facing increasingly stringent customer service and regulatory requirements.
