METHOD, ELECTRONIC DEVICE AND COMPUTER PROGRAM PRODUCT FOR DATA REPLICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240338143 titled 'METHOD, ELECTRONIC DEVICE AND COMPUTER PROGRAM PRODUCT FOR DATA REPLICATION
The techniques described in the abstract involve determining overlaps between target input/output operations and previous operations using a metadata log in data replication processes. Here is a simplified explanation of the abstract:
- Techniques for data replication involve checking for overlaps between target input/output operations and previous operations using a metadata log.
- If no overlap is found, the target input/output operation is written to a source data volume.
- If an overlap exists, data within the range of the overlap is replicated from the source data volume to a data log.
- The target input/output operation is then written to the source data volume after the replication is complete.
- Finally, the target input/output operation is replicated to a target data volume based on the metadata log and data log.
Potential Applications: - Data backup and recovery systems - High availability and disaster recovery solutions - Cloud storage and synchronization services
Problems Solved: - Ensuring data consistency and integrity in replication processes - Optimizing data transfer and storage efficiency - Facilitating quick recovery and restoration of data in case of failures
Benefits: - Improved data reliability and availability - Efficient utilization of storage resources - Streamlined data replication and synchronization processes
Commercial Applications: Title: Data Replication Technology for Enhanced Data Protection This technology can be utilized by data storage companies to offer reliable backup and recovery solutions to their clients. It can also be integrated into cloud storage services to enhance data synchronization and disaster recovery capabilities.
Questions about Data Replication Technology: 1. How does this technology improve data reliability in replication processes? 2. What are the key advantages of using metadata logs in data replication?
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.
