How do I remove .sparsebundle files in my home folder from being excluded by Time Machine? I have a problem in that any .sparsebundle I create in my home folder tree is not getting backed up to time machine.  

It is like an 'exclude by path' but I can't remove it or see where it is defined.

# whoami
root
# tmutil isexcluded /Users/andy/atest.sparsebundle /Users/Administrator/atest.sparsebundle
[Excluded]  /Users/andy/atest.sparsebundle
[Included]  /Users/Administrator/atest.sparsebundle
# defaults read /Library/Preferences/com.apple.TimeMachine.plist ExcludeByPath
(
    "//Users/Shared/adi",
    "/Users/Shared/adi",
    "/Library/Application Support/Microsoft/PlayReady"
)
# ls -l@ /Users/andy/atest.sparsebundle
-rw-r--r-- 1 root staff 0 18 Oct 20:54 /Users/andy/atest.sparsebundle
# xattr -l /Users/andy/atest.sparsebundle
# rm /Users/andy/atest.sparsebundle
# tmutil isexcluded /Users/andy/atest.sparsebundle
[Excluded] /Users/andy/atest.sparsebundle


Any ideas?
Have you tried removing the exclusion with the tmutil command?


  tmutil removeexclusion /Users/andy/atest.sparsebundle
