Disaster recovery planning with distributed replicated block device in synchronized API systems

Abstract System backup can’t be a good solution without planning. Secure data backup planning will prevent more data loss. The Comprehensive Exam is a system to conduct a comprehensive exam and test score management, which is also carried out with the Computer-Based Test. The two systems are connected, these are running with a data-based application programming interface (API) synchronization on two different servers. Two servers running simultaneously with the synchronized API. Special methods of solving this problem are needed to back up supported information systems and computer-based tests. Disaster Recovery is a term for recovery and resumption. A disaster recovery plan is a plan to improve information technology (IT) infrastructure from other disasters that endanger the information infrastructure. One method of recovering business processes is to restore the data backup itself. Data backup is one of the important elements, the data backup method will be applied is the disk mirroring method, which is making a permanent backup from the main data center, data backup will be provided a real-time backup using the Distributed Replicated Block Device (DRBD) concept. In our research concluded automatically synchronizes implementation backup data using the DRBD concept.
