How to tell time machine to ignore transcoded media? Since they can be generated at any time, there's no need to back it up. But they are not located in a single folder so I can't tell time machine to ignore it.

    You can't tell Time Machine what files to backup.


    You should have your Projects and Events on an External (Firewire or faster) HD (formatted Mac OS Extended - journaling is not important for video).

    For best performance, Events and Projects should not be on your system drive.

    System preferences. You have to do it for each event you create.

    Oh right?

    Can't really imagine why anyone would do that with video - I only use TM for backing up my system drive. I clone my Video Drives.


    You could work with Proxy media and delete all the Transcoded stuff - but you must remember to change to "Optimised or Original Media" in preferences before you export - otherwise you export very low quality media.


    Time machine will also have put the transcoded media on your backup drive, of course.

    SuperDuper from ShirtPocket.


    It has the ability to only clone the files that have changed, so you're not overwriting the massive video files all the time.

    I also use SuperDuper (SD), but I believe that Carbon Copy Cloner (CCC) is more versatile in terms of excluding folders, so it may work for you in this situation.


    There are two main disadvantages regarding using Time Machine versus using a clone tool like SD or CCC.

    One: TM will keep many versions of your files, and since they are so big and change a lot, this can fill up a drive pretty quickly.

    Two (and most important, IMHO): if your drive fails, with a clone you can just swap in the clone and be back to work, whereas with TM you'll have to restore, which may take hours.


    Personally, I use both for general documents (use TM several times a day and make a clone about once a day).

    For video, I don't use Time Machine.

    Just my $0.02

    Yep, I struggle to understand how developers would organize it such that no single folder could be ignored for transcoded files. This is just plain dumb & I don't see any reasonable excuse.


    However, no one has mentioned Backups for Final Cut Pro By NP Associates - which has knowledge of such things without doing anything special.




    PS I'm, on the bandwagon - I would never use Time Machine for this either.

    If Time Machine is setup for backing up a media drive, specific folders can be excluded, but it has to be done for each project manually as render files are not lumped together but are project specific.

  • Tom Wolsky Level 10 Level 10 (104,765 points)

    I'm sorry, that's not clear. What part are you trying to avoid? Having to tell the application for each new project? There is no software on the planet that can do that because every time you make a new project the directory structure is changing.

    I looked into superduper just now and I'm not seeing how I can ignore transcoded folders/files. And if I can't how is cloning any different than just using time machine?

    Not sure what happened yesterday, did this forum have some kind of melt-down?

    Anyway, my reply got deleted - here it is again.



    If you read the SuperDuper instructions, you'll see that you can exclude any folder you like:


    Here's a quote: (page 20)

    Excluding files or folders from a backup

    Although we recommend that a backup include all of the files from the source drive, it’s sometimes necessary – or desirable – to be more selective.

    SuperDuper!’s Copy Scripts allow a user to easily customize the files and folders that are copied, by simply building on the scripts we’ve provided. Don’t worry, this isn’t programming: scripts are just a way of selecting files and folders, and letting SuperDuper! know what to do with them.



    SuperDuper also has a "Smart Update" facility, where it only backs up files that have actually changed since the last backup. Final Cut Pro X is non-destructive editing, so the original media files themselves are only referenced (not changed) when you edit video - therefore, SuperDuper leaves the original media files alone - only copying changed project files and effects.


    My media, Events and Projects take up about 3 TB on a 4 TB HD.

    If I work all day on my projects, typically, SuperDuper will take about five or ten minutes to do a complete backup to my backup drive, making both drives identical.

    Wow!  FCPX 10.1 now puts all transcoded media in a single folder.  BUT it is now also inside a "pacakge" so it is not possible to select the "Transcoded Media" folder in time machine to tell it not to back it up.  Nice!
