How can I omit FCPX Render Files from a Time Machine backup? I want to be able to add my Final Cut Projects and Events folders to Time Machine, but annoyingly Apple have decided to put a Render Files folder within each and every Events folder.

Is there a way of moving the folders to a different location on the hard drive, such as a Caches folder? Or is there some way of telling Time Machine to ignore folders containing the words "Render Files" (using some kind of script perhaps)?
I have realised today, that OS X seems to automatically omit Render Files in the Time Machine Backup.

Apparently, Time Machine intentionally doesn't backup certain files/folder.  The file /System/Library/CoreServices/backupd.bundle/Contents/Resources/StdExclusions.pl‌​ist includes all absolute paths (globally and for each user) that TimeMachine ignores, as suggested by this article. File-patterns, are, however, not included in this file.

Note

I have examined this behaviour by comparing the two directories after a completed backup:

diff --brief -r timemachinefolder localfolder
