A new approach to disaster recovery as a service over cloud for database system

This paper presents a new approach to Disaster Recovery as a Service (DRaaS) over cloud for database system, which will ensure zero data loss and quick recovery. The solution makes use of internet small computer system interface (iSCSI) protocol, used for replicating database transaction logs over cloud infrastructure assuring zero data loss. The approach is well suited for any cloud environment, providing flexibility to cloud platform selection. The paper presents the detailed architecture and design using open source database Postgres to prove our point for Optimal DRaaS.
