Replication Using Logical Data Identifiers - A simplified explanation of the abstract

This abstract first appeared for US patent application 18541825 titled 'Replication Using Logical Data Identifiers

Simplified Explanation: The patent application describes a system and method for replicating data using different storage mediums. A selected snapshot is chosen for replication, and the primary storage medium of the snapshot is identified. The replica storage array determines a list of available medium extents, which are then sent to the original storage array. Only the medium extents corresponding to the primary storage medium that the replica storage array does not already have will be transferred. Additionally, the replica storage array can obtain medium extents from other source storage arrays during the replication process.

• The system selects a snapshot for replication.
• Identifies the primary storage medium of the snapshot.
• Determines available medium extents for replication.
• Transfers only the necessary medium extents to the replica storage array.
• Allows for obtaining medium extents from other source storage arrays during replication.

Potential Applications: 1. Data backup and disaster recovery solutions. 2. Cloud storage services. 3. Data migration between storage systems.

Problems Solved: 1. Efficient replication of data using different storage mediums. 2. Minimizing data transfer by only sending necessary medium extents. 3. Enhancing data redundancy and availability.

Benefits: 1. Improved data replication efficiency. 2. Reduced data transfer costs. 3. Enhanced data protection and redundancy.

Commercial Applications: The technology can be utilized in cloud storage services, data centers, and enterprise storage solutions to enhance data replication processes, improve disaster recovery capabilities, and optimize data migration tasks.

Questions about the Technology: 1. How does the system ensure data consistency during the replication process? 2. What security measures are in place to protect the transferred medium extents during replication?

Frequently Updated Research: Stay updated on advancements in data replication technologies, storage mediums, and disaster recovery solutions to enhance the efficiency and effectiveness of the patented system.

Original Abstract Submitted

A system and method for performing replication using mediums. A snapshot ‘S’ is selected for replication, and the anchor medium ‘M’ of S is identified. The replica storage array ‘R’ to which M is being replicated determines a list of medium extents which are available. R sends this list to an original storage array ‘O’ and O generates a list of medium extents which need to be sent to R. Only those medium extents corresponding to M which R does not already have will be sent from O to R. Also, R can obtain medium extents from other source storage arrays during the replication process.
