Abstract
Metadata generate for incremental backup is disclosed. A subset of blocks used to store file system metadata are identified in a set of blocks changed since a last backup. File system metadata stored in the subset of blocks is used to obtain file system metadata associated with file system objects that have been created and/or modified since the last backup. The file system metadata associated with file system objects that have been created and/or modified since the last backup is used to generate file system metadata files for the incremental backup.
