METHOD, ELECTRONIC DEVICE AND COMPUTER PROGRAM PRODUCT FOR DATA REPLICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18382161 titled 'METHOD, ELECTRONIC DEVICE AND COMPUTER PROGRAM PRODUCT FOR DATA REPLICATION
Simplified Explanation: The patent application discusses techniques for data replication based on metadata logs to determine overlaps between target input/output operations and previous operations, replicating data accordingly.
- Techniques involve determining overlaps between target IO and previous IOs based on metadata logs.
- Writing target IO to source data volume if no overlap exists with previous IOs.
- Replicating data within the overlap range from source data volume to a data log if overlap exists.
- Writing target IO to source data volume after completing replication.
- Replicating target IO to target data volume based on metadata and data logs.
Key Features and Innovation: - Utilizes metadata logs to determine overlaps in data replication. - Efficiently replicates data based on overlap analysis. - Streamlines the process of writing target IO to source and target data volumes.
Potential Applications: This technology can be applied in data backup systems, disaster recovery solutions, and cloud storage services.
Problems Solved: - Streamlines data replication processes. - Improves efficiency in managing data backups. - Enhances disaster recovery capabilities.
Benefits: - Faster and more accurate data replication. - Improved data management and backup processes. - Enhanced disaster recovery capabilities.
Commercial Applications: Data replication technologies like this can be utilized by cloud service providers, data centers, and enterprises requiring robust backup and disaster recovery solutions.
Questions about Data Replication Techniques: 1. How does the use of metadata logs improve data replication efficiency? 2. What are the potential drawbacks of relying on metadata logs for data replication analysis?
Frequently Updated Research: Stay updated on the latest advancements in data replication technologies to ensure optimal performance and security in data management practices.
Original Abstract Submitted
Techniques for data replication involve determining, based on a metadata log, whether an overlap exists between a target input/output operation or target IO and previous IOs, wherein the metadata log records metadata related to data replication. Such techniques further involve writing the target IO to a source data volume according to a determination that no overlap exists between the target IO and the previous IOs. Such techniques further involve replicating data within the range of the overlap from the source data volume to a data log according to a determination that the overlap exists between the target IO and the previous IOs, and writing the target IO to the source data volume after completion of the replicating. Such techniques further involve replicating the target IO to a target data volume based on the metadata log and the data log.
