I have been working toward organizing my photos into a managed Aperture library. I have about 130k pictures from the last 14 years of digital photography so the sins of disorganization are coming home to roost. It's a tedious process, but I am making progress. I have 3 questions: 1. Is there an advantage to using the Aperture Vault if I backup my hard drive using Carbon Copy Cloner? I haven't done a backup yet since importing my photos into the managed library, and I wonder if CCC will be a very lengthy process every time I back up from now on, since the Aperture library is basically just one big file. 2. Why doesn't the Aperture library work like itunes? iTunes has a front end library and manages the files in the Finder structure automatically, but the individual songs are still readily accessible individual files. Aperture does essentially the same thing, but insists on using one big, non-user accessible structure (for all intents and purposes) for the file structure. Seems like they could have implemented it the same way in Aperture to have the best of both worlds (referenced and managed). 3. Quitting Aperture seldom works correctly and I often have to 'force quit'. It usually hangs on "Updating information for sharing previews". Is this a common problem? Would repairing the database help? Thanks EDIT: Title should be "3 Aperture 3 questions". Thought of another one mid post.
