Add a test for xfsdump -D, which skips unchanged directories during an incremental backup. After doing an initial backup, a new file is added to one directory (to verify that changed directories are backed up) and several files are appended to. Then an incremental backup is done with -D set. The test verifies the original and restored filesystems match after applying the base and incremental backups, and that the incremental restore output indicates that only the one changed directory was backed up.
