Lightroom: Ability to create catalog/photo collection archives
I'd like to archive several large Lightroom photo collections. I want the archive to include the original RAW photos (of course!) and all derivative images and catalog information (e.g., virtual copies, develop module adjustments, etc). It should be possible but not necessary to separate an archived collection from the images registered with Lightroom, and it should be possible to attach or reattach an archive to Lightroom. An archive NOT separated from the Lightroom database should be updatable. An option to create archives in sections that will fit on standard DVDs would be appreciated.
