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.
