Time Machine exclusions added via tmutil do not appear in TM "Options" list I can successfully add Time Machine exclusions using tmutil addexclusion and I can verify exclusions successfully with tmutil isexcluded but if I then open up Time Machine's Preferences and click "Options..." none of the exclusions added via tmutil are listed.


Use of the -p option when using tmutil addexclusion seems to make no difference.
Restarting the OS makes no difference.
Re-indexing Spotlight makes no difference.


I've tested this on both Mac OS 10.9 and 10.11.

Is this expected behaviour?
Aaah, the following page seems to suggest that this is in fact expected behaviour:

Exclusions Not Shown on the Preferences Window
Fixed Path Exclusions are set by the CSBackupSetItemExcluded API or sudo tmutil with the -p option, whether the item exists or not.
Sticky exclusions are set in an item's extended attributes, via the CSBackupSetItemExcluded API, xattr, or tmutil without the -p option.
