A data management system (DMS) may receive entries corresponding to files and directories of a storage system that changed within a time period. The received entries may include metadata associated with the changed files and directories. The DMS may identify one or more directories that were renamed or deleted within the time period by analyzing the metadata from the received entries. The DMS may identify descendent directories and descendent files corresponding to the one or more renamed or deleted directories. The DMS may update path identifiers associated with the descendent directories and the descendent files based on the metadata from the received entries. The DMS may generate an updated index file based on updating the path identifiers for the descendent directories and the descendent files. The described techniques may enable the DMS to identify renames and deletions with greater efficiency, among other benefits.
