Can someone clear something up for me? When Time Machine notifies me that it is deleting backups because the drive is out of space, does that mean my oldest data isn't being backed up? My time machine backup is full, but it is 2TB in size, but it is backing up my Mini, as well as my drive of media (movies, picture, TV shows and music), which is around 1.4TB right now. I just want to be sure my oldest media isn't going to be lost if something happens. If the old stuff is NOT being backed up, then I need to wipe my Time Machne drive and do a full, fresh backup more often (like every few weeks I'd guess). Thoughts?
