Towards instant service rebuilding after site corruptions

Zheng Weimin

Strategic Study of CAE 2009, Volume 11, Issue 10, Pages 32-38

Abstract:

The paper describes a new system protection method which is used for disaster recovery. It abandons the traditional data protection based DR(disaster recovery) achieves, replicates the whole system states, including data states together with service running states, and further introduces the method of parallel recovery to restore the interrupted services instantly. Compared with traditional techniques, the method can be independent from specific devices and applications. Different systems can share a unique DR system which is resource-saving.
