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/‌​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.


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

diff --brief -r timemachinefolder localfolder

The list suggests these exclusions are from CCC and not Time Machine. In your research, did you find anything from Apple about this behaviour? – Graham Miln Jan 24 at 13:09
Correct, and that bugged me as well. I could reproduce the behaviour on my local machine, but I would love to see official documentation on this. Will change my wording regarding the link. – Sebastian Hojas Jan 25 at 9:28
An article on shiftedbits reveals the following file /System/Library/CoreServices/backupd.bundle/Contents/Resources/‌​ist. This file contains all that Time Machine skips by default on OS X! – Graham Miln Jan 25 at 10:10
That helps a lot, but it only includes absolute paths (for globally and for each user), not specific folder patterns, for instance. PS: I have just realised my fail that the article didn't even relate to TimeMachine. My bad, and thanks for the correction! – Sebastian Hojas Jan 25 at 10:16
