Time Machine won't back up DRM protected files
Time Machine won't back up iTunes movie downloads, but DRM-free videos in my TV library are backed up. Is it designed to function like this? Do I have to manually copy the DRM protected files to the external drive in case they are unavailable in the future? Will I be able to watch the movies if I drag them back to my Mac from the external drive? Thank you in advance.
