Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data protection systems face challenges in maintaining continuous data protection, particularly in keeping pace with high data transaction rates at production sites without slowing them down, leading to potential backlogs and system shutdowns.
Innovation Solution
A method and system for performing data replication and backup using a five-state journaling process that includes initializing backup snapshots on deduplicated storage, maintaining continuous data replication, and synthesizing new backup snapshots, allowing for efficient data synchronization and recovery across sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If journaling is used to enable continuous data protection and rollback to any point in time, then data recovery flexibility is improved, but the overhead of multiple data transactions at the backup site increases, causing the backup site to fall behind when data transaction rates are high
Solution Approach 1:
The patent segments the backup system into multiple backup sites, each maintaining its own journal and backup copies. This allows the backup function to be distributed across multiple independent processing units, enabling parallel processing of data transactions and preventing any single backup site from becoming a bottleneck when handling high data transaction rates.
Solution Approach 2:
The patent combines multiple backup sites working in parallel to collectively handle the backup workload. By merging the capabilities of multiple backup sites, the system can process high volumes of data transactions without forcing the production site to slow down, while still maintaining the ability to rollback to any point in time through journaling.
2Reliability
If the production site is forced to slow down to allow the backup site to keep pace, then backup completeness is improved, but production site performance deteriorates
Solution Approach 1:
The patent divides the backup function across multiple backup sites, allowing the production site to maintain its performance while the segmented backup infrastructure handles the workload in parallel. Each backup site processes a portion of the data transactions independently, preventing the need to throttle production site performance.
Solution Approach 2:
The patent transitions from a single backup site model to a multi-dimensional backup architecture with multiple sites operating in parallel. This dimensional expansion of the backup infrastructure provides the scalability needed to handle high data transaction rates without impacting production site performance.
3Device complexity
If a single backup site is used, then system simplicity is maintained, but the ability to handle high data transaction rates without backlog is limited
Solution Approach 1:
The patent segments the backup function into multiple independent backup sites, each capable of processing data transactions independently. This segmentation increases the overall data transaction handling capacity of the backup system while maintaining relatively simple individual backup site structures that can be managed independently.
Solution Approach 2:
Each backup site in the patent is designed to be a universal, self-contained unit that can independently perform complete backup functions including journaling and data replication. This multi-functionality at the backup site level allows the system to scale capacity by adding more identical units without increasing the complexity of individual components.

AI summary
Example embodiments of the present invention relate to a method, a system, and a computer program product for performing data replication and backup. The method comprises performing a first data replication of a production site storage to a replication site storage and performing a first backup of the production site storage to a production site backup storage. A second data replication then may be performed from the production site backup storage to a backup site backup storage.
