  • System for performing incremental file system check
    Patent number: 7900088
    Abstract: A method and apparatus for performing incremental file system checks is described which uses file system information to identify changes that have occurred to a file system between checkpoints. The set of changes can be represented by bitmaps and data structures which may be used by file system check utilities to identify potential errors and to remedy these errors if appropriate. Verifying only file system changes greatly reduces the processing overhead associated with typical backup and recovery mechanisms.
