  • FCPBUNDLE Backed up to ISO problem

    Posted by Scott Thomas on February 22, 2023 at 10:25 pm


    For some time I have been backing up projects to Blu-Ray disks. I tried to copy one of those ISO disks to another medium and have been running into an issue. The copy fails at the point where the .fcpbundle is being copied and it reaches an alias to a media file in the “original media” folder. I get this error in the terminal: “Unknown error: 10000”. So it appears that MacOS alias files don’t survive when burnt to an ISO format disk.

    Thankfully I’m not in any crisis, but I would like to know if there is something I’m missing, or if there’s some workaround. Appreciate any help.

    I’ve done a little more digging. I’m reading the man file on ‘cp’ (The terminal command). On suggestion is: “Note that cp copies hard-linked files as separate files. If you need to preserve hard links, consider using tar(1), cpio(1), or pax(1) instead.”

    One nice thing about using the terminal to do the copy is that the -R switch with ‘cp’ not only does the recursive copying with the folder structure, it also continues after the error of the failed alias copy. Finder on the other hand fails and doesn’t recover very well.

    So, I guess the answer is, that burning a FCPX project onto an ISO format where the project has alias links to media is problematic.

    Technically the aliases survive, but the links are broken the minute you cross from one drive to another. They are meant to only work with files on a single drive.

    You need to “Consolidate” the Library first.

    BluRay seems a very slow, ineffective, and expensive way to backup Libraries, though.

    Ben, good call on consolidating.

    On bigger projects, and FCPX libraries, yes, BluRay might not be optimal.
    Better get some SSD/hard-drives – although they too comes with their own set of issues.

    I do use BluRay on my PPro projects and slow digitization of my Betacam SP masters, and with up to 50GB discs, I can store most of the rushes for short-form edits too.
    Should add that I always do two discs of each backup.
    So far that has worked fine.

    Thank you both for the information and advice.

    I usually bundle up projects every couple of months and burn disks overnight. While not fast, I’ve cataloged everything with NeoFinder and I can usually find anything I’ve done over the last 25 years (CD-Rs and DVDs back in the day). Then the problem becomes, do I have a program that will open the file, or the codec? 🙂
