I’m trying to exclude some directories and hidden directories from an rsync process.

I noticed the following behaviour with rsync --exclude flag:

The following excludes .git directory. "" is essential.

rsync -av --exclude=".git" ./data ./scratch 

The following excludes Test_Data directory

rsync -av --exclude=./data/Test_Data/ ./data ./scratch

However, combining the two includes Test_Data directory but still excludes .git directory

rsync -av --exclude=".git" --exclude=./data/Test_Data/ ./data ./scratch

Swapping the order still excludes .git directory and includes Test_Data

rsync -av --exclude="./data/Test_Data/" --exclude=".git" ./data ./scratch

I’ve tested variants of single '' or double "" or no quotes. I’ve also tested the syntax:

--exclude={"./data/Test_Data/",".git"}

and the performance is the same. What is the correct way to exclude both a hidden directory and a directory with rsync or is this not possible?
