I agree with Neil, if any directory named "Downloads" is excluded, dar
won't recurse in it and the ending /* is useless for that reason (this
is a glob expressions, type "man 7 glob" for details)

providing -P "*/Downloads/*" will never remove "/home/me/Downloads"
because it does not match du to the training /. However any
subdirectory found inside home/me/Downloads will be excluded like for
example:
   /home/me/Downloads/documents

Well, the code is the same between Cygwin and Linux and I have no
problem here with -P option following your example and using 2.6.2 on
Linux. This might well be a bug but so far it does not seems the most
probable explanation. Can you thus try the following:

for all the following tests, you can add the --empty option to perform
a dry-run execution: this will be faster and will save you disk space
to store the test archives.


1 - add -vm option as *first* argument of dar and provide to the
mailing-list the options list displayed by dar at the beginning
(replace password or any other sensible data with ### if necessary).

2 - check that the 'find' commands matches the files you expect to
exclude:

find / -path "*/Downloads/*" -ls

3 - add the -an option to dar before any filter option (-P, -g, -I,
- -X, ...) an see if that does not work better, excluding the expected
directories. This would indicate a case sensitivy issue (uppercase
instead of lowercase or viceversa)
