MongoDB has been granted a patent for a database system that efficiently performs backup commands in parallel with write commands. The system includes a primary storage node and secondary nodes, ensuring data integrity without requiring additional disk capacity. Each backup command opens only one backup cursor, optimizing storage resources. GlobalData’s report on MongoDB gives a 360-degree view of the company including its patenting strategy.

Database system with parallel backup and write commands
A recently granted patent (Publication Number: US11829253B2) discloses a database system that includes a plurality of data storage nodes forming a replica set, with a primary storage node and multiple secondary storage nodes. The system is designed to perform write commands to secondary storage nodes and backup commands in parallel, utilizing data snapshots without requiring additional disk capacity. Each backup command opens only one backup cursor, with storage resources released based on the receipt of a heartbeat signal within a specified time interval. The system is also capable of validating storage engine support for backup commands and can operate with components that both support and do not support these commands, following an eventual consistency model.
Furthermore, the patent describes a method and a computer-readable storage medium for performing backup commands in a database system with a replica set of data storage nodes. The method involves executing write commands and backup commands concurrently, utilizing data snapshots from secondary storage nodes without the need for additional disk capacity. Similar to the database system, the method ensures efficient resource management by limiting the number of backup cursors opened and releasing storage resources based on heartbeat signal reception within a defined time frame. The computer-readable storage medium also includes instructions for validating storage engine support for backup commands and can operate with components that have varying levels of support for these commands, all while adhering to an eventual consistency model.
