If system A fails, clients can immediately connect to system A' while system A is restored. Common to all configurations, system A is continually backed up to system A'. The diagrams below show typical configurations.
DRS Configurations There are multiple server configurations that can be used in Disaster Recovery s. However, in most cases, the cost of meeting these objectives for all the risks mentioned above is prohibitive and businesses make compromises. Primary Backup RPO 2 3 Disaster RTO Recovery A B Time In the ideal case both the RPO and the RTO would be zero. The RTO is the acceptable limit of service outage. The RTO is the period between the disaster and recovery, when service is resumed through the operation of the backup system, represented by updates A and B being made at the backup system.
The RPO determines the amount of updates that are lost in case of a disaster. If the replication is asynchronous, then at the time that the disaster hits, the backup system may not have all the updates that were made at the primary system. Avid MediaCentral Platform Disaster Recovery s Version 1.0 Ĥ In the diagram below, the data updates made at the primary system on the top is continually replicated to the system on the bottom. Recovery Time Objective (RTO) - The targeted duration of time in which services must be restored after a disaster. Recovery Point Objective (RPO) - The maximum targeted period in which data might be lost from a service due to a disaster.

Below is a table that shows common operational risks, with examples and possible solutions to mitigate the risks: Risks Example Solution Hardware / Software failure Localized outage Site outage Server crash Loss of power to rack Data center flooding Cluster / Failover / No single point of failure Local Replication Regional replication Disaster Recovery Metrics The key metrics to measure the effectiveness of a DRS are Recovery Point Objective and Recovery Time Objective. Operational risk is managed by keeping losses within some level of risk tolerance (i.e., the amount of risk one is prepared to accept in pursuit of one's objectives), determined by balancing the costs of improvement against the expected benefits. Operational Risks In general, operational risk is defined as the risk of losing value caused by inadequate or failed internal processes, people and systems, or from external events. It identifies the risks that a DRS needs to account for, key metrics, and DRS configurations for systems running on the Avid MediaCentral Platform. This article is an overview of key concepts for understanding and building a DRS. Disaster recovery is a set of policies, procedures, and systems to enable the continuation of critical business functions when services are interrupted due to hardware failures, software failures, and natural or human-induced disasters. To mitigate the risk of outages, customers can leverage the flexibility of the MediaCentral Platform to deploy a Disaster Recovery (DRS). Any outage of the systems on the platform may result in disruption of business continuity and financial loss. 9 inews Regional Replication Interplay MAM Replication Interplay MAM on VMware HA Virtual Machines Conclusion Appendix A Scripts to Mirror an Interplay Production mirror_interplay.bat mirror_interplay_users.bat Appendix B Using Rsync or Unison to Synchronize Files on ISIS robocopy_mirror.bat rsync_mirror.bat Unison_mirror.bat Unison_sync.bat Avid MediaCentral Platform Disaster Recovery s Version 1.0 ģ Overview Media professionals rely on the Avid MediaCentral Platform for critical business functions. 7 Interplay Production Regional Replication. 6 Interplay Production Local Replication. 1 Avid MediaCentral Platform Disaster Recovery s Version 1.0Ģ Contents Overview.
