Email Redirection During Outages via Selective Data Replication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing email replication systems are costly, complex, and prone to failures due to database corruption, virus transmission, transactional inconsistencies, and lack of vendor-supported solutions, leading to inadequate email continuity during unplanned outages.
Innovation Solution
A method and system that redirects inbound email messages from a primary server to a secondary server during outages, notifies users, and synchronizes email messages to create a complete history upon primary server availability, allowing for efficient and cost-effective email processing without requiring complete system replication or offline primary server testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete system replication is implemented to ensure email continuity during outages, then email availability is improved, but system complexity and cost increase significantly
Solution Approach 1:
The patent segments the email system into primary and secondary servers, with only critical email address data being replicated to the secondary server. This selective segmentation reduces the complexity of full system replication while maintaining email continuity during outages.
Solution Approach 2:
The patent creates a simplified copy of only the essential email address data on the secondary server, rather than replicating the entire complex email system. This copying approach ensures availability while reducing system complexity and resource requirements.
2Reliability
If real-time database replication is implemented to prevent data loss, then data integrity is improved, but the risk of virus transmission and database corruption increases
Solution Approach 1:
The patent extracts only the essential email address data from the complete database, excluding potentially harmful elements such as viruses and corrupt files. This extraction approach maintains data integrity for critical information while eliminating the risk of propagating harmful factors through replication.
3Manufacturing precision
If byte-level replication is used to ensure complete data copying, then replication completeness is improved, but transactional inconsistency and file corruption occur
Solution Approach 1:
The patent performs preliminary actions by validating and preparing data before replication, ensuring that only consistent and complete email address information is copied to the secondary server. This prevents transactional inconsistency and file corruption that would result from incomplete byte-level replication.
4Reliability
If third-party replication software and full system replication are implemented, then email continuity is improved, but implementation cost and resource requirements increase
Solution Approach 1:
The patent applies partial action by replicating only the essential email address data rather than the complete email system. This selective replication achieves email continuity during outages while significantly reducing the resources required for implementation and maintenance.

AI summary
The method and system of the present invention provides an improved technique for processing email during an unplanned outage. Email messages are redirected from the primary server to a secondary server during an unplanned outage such as, for example, a natural disaster. A notification message is sent to users alerting them that their email messages are available on the secondary server by, for example, Internet access. After the termination of the unplanned outage, email messages received during the unplanned outage are synchronized into the users standard email application.
