The granted patent (Publication Number: US11886298B2) outlines a method for efficiently managing backups in a storage system. The method involves receiving an identification of a new primary snapshot, determining a threshold time window based on the capture time of the snapshot, analyzing entries in the storage log to identify changed objects, and capturing these changes in a new secondary backup stored at a secondary storage system. The process includes comparing metadata of the new primary snapshot with the previous backup to determine changes in objects, such as files and directories. Additionally, the method involves generating incremental backups based on identified changes, ensuring data integrity and efficient storage management.

Furthermore, the patent describes the identification of various types of changed objects, including created, deleted, modified, or moved files and directories. It also addresses scenarios where the capture time of the primary snapshot is not reflected in the storage log, emphasizing the importance of accurate data tracking. The method involves creating change lists for capturing identified changes in the new secondary backup, optimizing backup processes. The patent also details the use of timestamps and clocks to determine threshold time windows for backup operations, ensuring timely and effective data protection. Overall, the patented method offers a systematic approach to backup management in storage systems, enhancing data security and operational efficiency.
