Processed File Replication for Cross-Region Disaster Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems struggle to effectively minimize data loss and ensure data availability during cross-region disaster recovery in cloud configurations, particularly in the event of a major disaster affecting primary servers, while achieving prompt service availability in the secondary region.
Innovation Solution
A computer-implemented method for cross-regional disaster recovery involving data replication from an active deployment to a standby deployment, ensuring seamless transition and maintaining data availability by replicating files generated during processing to a scalable storage module in the standby deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is replicated from active deployment to standby deployment for disaster recovery, then data availability in secondary region is improved, but data loss during transition cannot be minimized
Solution Approach 1:
The patent applies preliminary action by pre-replicating files generated during data processing from the active deployment to the standby deployment before a disaster occurs. This ensures that the standby deployment already has copies of processed files ready, minimizing data loss during failover while maintaining data availability in the secondary region.
2Reliability
If conventional disaster recovery systems are used, then service availability in secondary region is achieved, but transition time is delayed
Solution Approach 1:
The system performs preliminary replication of processed files to the standby deployment before disaster occurs, so that when failover is needed, the transition can happen immediately without waiting for file replication, thus reducing transition time while ensuring service availability.
Solution Approach 2:
The patent uses copying by creating duplicate copies of processed files in the standby deployment. This allows the system to switch to the standby deployment quickly by simply pointing to the copied files, rather than transferring them during disaster recovery, thereby reducing transition time.
3Adaptability or versatility
If all generated data is stored for later analysis, then analytical flexibility is improved, but storage and processing complexity increases
Solution Approach 1:
The patent extracts only the files generated during data processing (rather than storing all raw data) and replicates these to the standby deployment. This selective extraction maintains analytical flexibility for processed data while reducing storage and processing complexity compared to retaining all generated data.

AI summary
A computer-implemented method for performing cross regional disaster recovery includes receiving event data at an active deployment of a data intake and query system. The method further includes processing the event data in a plurality of stages of the data intake and query system to convert the event data into searchable buckets of indexed data, wherein files generated at each stage of the processing are uploaded to a first scalable storage module in the active deployment. Further, the method includes replicating the files generated at each stage of the processing to a second scalable storage module in a standby deployment of the data intake and query system. Responsive to an outage at the active deployment, the method includes transitioning control to the standby deployment and recovering the event data at the standby deployment using the files replicated to the second scalable storage module.
