I am trying to back up an external hard drive with Time Machine, but in Options, the drive is greyed out and cannot be removed from exclusions.

I read that it cannot back up Fat32, if that is true, how do I work around that?  My Aperture library is on this drive.

    If the drive is formatted FAT32 then there is no way around it. Time Machine will not be able to backup the drive. You would have to repartition and reformat the drive for OS X, but that will make it unusable on a PC. You should try using a third-party backup utility if you cannot reformat the drive:

    Carbon Copy Cloner

    Data Backup

    Deja Vu

    SuperDuper!

    Synk Pro

    Tri-Backup

     

    Others may be found at VersionTracker or MacUpdate.

     

    Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files.

     

    If you backup to the same drive used for your Time Machine backup, then you should create a separate partition on the drive for these backups.

    The drive must be formatted in Mac OS Extended (Journaled) to work with Time Machine.

    You will have to move the Aperture library to another location for temporary storage. Then format the drive for Mac and move the library back to the drive.

     

    Once this is done, Time Machine will backup both your Mac and the external hard drive.

    by moving the Aperture library, will that cause issues at all when I reopen the program?  Will it have to re-index all of the files

    That is a question for the guys over in the Aperture forum. I've done this with iPhoto libraries and there are no issues at all, but I have not used Aperture.

     

    I imagine that you will have to "point" the Aperture application to the "new" location of the library on the external hard drive once it has been re-formatted and the library has been moved back over. 

     

    At least that is the way that it works with iPhoto....you hold down the option key on your Mac while starting the iPhoto application and simply point to the location of the library. After that, iPhoto knows where the library is located and will open it automatically when the application starts.

    I believe that you can point Aperture to the new location of the library by going into Aperture Preferences. Check with the Aperture gurus to confirm on that though, as I'm working from memory on quick look at Aperture some time back.
