Disaster recovery is an important capability of cloud system. Enterprise pay much attention to DR and ensure their applications are able to survive large scale disasters. Openstack now have volume based replication in Cinder project, it make users could failover and failback their volume by leveraged replication feature in storage backends when disaster happened. But that's not only way to gain DR capability, we would like to share our DR solution and we will introduce how does it work on hypervisor level. We will compare this solution and volume based replication and show the advantages/disadvantages about it. We wish this kind of DR solution will bring one more choice to Enterprise users and their cloud.
