ABSTRACT:
An embodiment of the invention provides a traversal engine that traverses (walks) through metadata containers (e.g., inodes) in a file system and determines the metadata containers that have been modified (added, changed, deleted, or renamed) within a particular time interval. A modified metadata container corresponds to a data container (e.g., file or directory) that has been modified within the particular time interval. The traversal engine records, into a table, information about the modified metadata containers. The traversal engine also records, into the table, parent information corresponding to an immediate parent of a modified data container.
