Study on Virtualization-based Backup System Model for Disaster Recovery

Studying against deficiencies in traditional backup system for disaster recovery such as difficult to maintain and manage,low in resource utilization and scalability,an idea mat design backup system for disaster recovery based on virtualization is emerged.Key technologies such as server virtualization,network virtualization and storage virtualization are analyzed.A backup system model for disaster recovery which is centered on resource pool management with demand analysis,disaster backup,disaster recovery,disaster exercises and disaster warning is studied and designed.Finally,the system recovery performance of virtualization-based backup system for disaster recovery is proved through test to be much better than that of traditional backup system for disaster recovery.
