I have a bunch of files that are messing up my backup system (via rsync). The permissions are all question marks. How does this happen? How do I find them / scan for them? This partially breaks my backup system and I need to clean them up before the backup system runs.

This happens if the user you are using to access a directory does not have execute permission on the directory iteself. To list the contents of a directory read permission is enough. But to cd into the directory or show the permissions of files etc. inside the execute permission is needed:
user@server ~ $ ls test/ -la
total 0
d????????? ? ? ? ? ? .
d????????? ? ? ? ? ? ..
?????????? ? ? ? ? ? testdir1
?????????? ? ? ? ? ? testdir2
?????????? ? ? ? ? ? testdir3
?????????? ? ? ? ? ? testfile1
?????????? ? ? ? ? ? testfile2
?????????? ? ? ? ? ? testfile3
user@server ~ $ sudo chmod u+x test/
user@server ~ $ ls test/ -la
total 4
drwx------ 5 user user 99 Mär 21 17:45 .
drwx------ 14 user user 4096 Mär 21 17:44 ..
drwx------ 2 user user 6 Mär 21 17:45 testdir1
drwx------ 2 user user 6 Mär 21 17:45 testdir2
drwx------ 2 user user 6 Mär 21 17:45 testdir3
-rw------- 1 user user 0 Mär 21 17:45 testfile1
-rw------- 1 user user 0 Mär 21 17:45 testfile2
-rw------- 1 user user 0 Mär 21 17:45 testfile3
So you or your user which runs the backup probably does not have execute permission on some files etc.
