Hosted Exchange Mailbox Replication for Disaster Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for ensuring business continuity of email services during disasters are complex, costly, and often require additional hardware or software, leading to resource contention issues and lock-in with specific vendors, while failing to provide a simple and efficient method for secure offsite email storage and retrieval.
Innovation Solution
A multi-tenancy hosted/managed services solution for Microsoft Exchange that allows secure offsite email storage and retrieval without requiring additional infrastructure, enabling easy access to email messages during disasters and providing regulatory compliance services, with no impact on existing Exchange solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software replication solutions are implemented to replicate Exchange mail stores to secondary servers, then business continuity capability is improved, but device complexity and resource contention issues worsen
Solution Approach 1:
The patent creates a simplified copy mechanism by establishing a direct replication connection between the primary Exchange server and the hosted Exchange mailbox environment. Instead of complex software replication solutions requiring one-to-one copying with multiple components, the system uses a streamlined copying approach where mailboxes are replicated to a hosted service that manages the secondary copies, reducing overall system complexity while maintaining business continuity capability.
Solution Approach 2:
The patent introduces a hosted Exchange mailbox service as an intermediary between the primary Exchange server and the disaster recovery infrastructure. This intermediary manages the replication and storage of mailboxes, eliminating the need for complex direct peer-to-peer replication setups and reducing resource contention issues that arise from multiple replication agents running on primary servers.
2Reliability
If hardware appliances are deployed to provide highly available Exchange instances, then reliability is improved, but cost and ease of manufacture worsen
Solution Approach 1:
The patent creates a universal hosted Exchange mailbox service that can serve multiple customers and purposes through a single infrastructure. Instead of deploying dedicated hardware appliances for each customer, the system provides a multi-tenant hosted environment where Exchange mailboxes are replicated to a shared infrastructure that serves disaster recovery needs for multiple organizations, significantly reducing per-customer implementation costs while maintaining high availability capability.
3Manufacturing precision
If storage vendor block-level replication is implemented, then data integrity is improved, but adaptability and ease of operation worsen
Solution Approach 1:
The patent creates a vendor-agnostic hosted Exchange mailbox service that can receive replicated mailboxes from any Exchange environment regardless of the underlying storage vendor. The hosted service provides a universal interface and storage abstraction layer that accepts mailboxes from diverse sources and provides consistent disaster recovery capabilities, eliminating vendor lock-in while maintaining data integrity through proven Exchange-to-Exchange replication mechanisms.
4Reliability
If one-to-one replication relationships are established from production to backup instances, then reliability is improved, but ease of operation and adaptability worsen
Solution Approach 1:
The patent introduces a hosted Exchange mailbox service as an intermediary that consolidates multiple backup destinations into a single managed service. Instead of configuring and managing separate one-to-one replication relationships to multiple backup servers, the system replicates mailboxes to a centralized hosted service that manages the backup infrastructure, significantly simplifying operational management while maintaining reliable disaster recovery capability.
Data Source
AI summary
A method for processing electronic communications is described. The method includes receiving electronic communications from a plurality of sources and processing the communications for delivery to intended addressees. The processing includes ensuring validity of sender, verifying operation of exchange mailbox corresponding to said addressee and routing the communication along a particular path based on the validation and verification.
