  • Summary file change log for faster forever incremental backup
    Patent number: 11093340
    Abstract: Systems and methods for performing backups including incremental backups are provided. A change log is provided. The change log includes a map file that includes a bit for each inode in a file system. The bits are set on certain file events. The map file allows the files to be included in the next backup to be identified without having to trawl the entire file system. The change log also includes a data file that lists actual changes to the various files in corresponding records that are indexed by the inode number. The change log can enable faster incremental backups in part by eliminating unnecessary disk access requests.

  • OPTIMIZING INCREMENTAL BACKUPS
    Publication number: 20210034709
    Abstract: Systems and method for performing backup. A layered file system is provided that is configured to detect all transactions with a physical file system. Based on an analysis of the transactions, records are selectively entered into a change log. A backup agent is able to generate a backup based on the change log, which reflects data that has changed or that needs to be backed up relative to the previous backup.
