In the world of Information Technology (IT) and infrastructure, whether in the banking sector, broadcasting industry, telecommunications, or many other sectors, ensuring business continuity when disaster strikes is critical to success in business and sustainability in the industry.
Disasters come in two main categories: natural (e.g. floods, earthquakes) and man-made (e.g. data corruption, hardware failure, human error). Disaster recovery can be implemented in many ways; setting up a disaster recovery site and deploying backup servers and PCs to be managed by a staff team could be costly and not time efficient, and data integrity could also be compromised due to systems downtime.
Etere developed Disaster Recovery (DR) to enable business continuity during a disaster, providing recovery capability to avoid interruption and data loss to mission-critical applications. For physical redundancy, Etere Disaster Recovery performs real-time replication by synchronizing a replicated copy of published playlists (from the Main Server) to the disaster recovery server (Backup Server) at the DR site. When disaster strikes, the Backup Server is activated and resumes the roles of the Main Server. The Disaster Recovery site can have a different configuration independent from the Primary site (refer to next chapter," "The Advantage of Etere Disaster Recover").
Etere Disaster Recovery Server is deployed in different regions and different power grids to achieve 99.99% availability of critical applications. The disaster recovery capability is embedded into Etere Solution. All Etere application modules run in Microsoft SQL Server; in a disaster recovery implementation, Etere application modules must be installed in both Main and Backup SQL Server having the same version and set to "Full Recovery Mod" to achieve full redundancy.
