How to create one main backup and simply add to it?
I've been using Time Machine for over a year. I've gotten to the point where it has taken up all the space on my external HD. The last few months, I've wondered why instead of making a full copy of my entire drive, there isn't an option to simply add whatever is new to one back up file. My dilemma with TM simply adding an entirely new back up is eventually, when it goes to delete an old back up, it inevitably will remove content that I have since deleted off my computer and that was not then copied in a recent backup; I'm actually losing files with TM. Is there a way to have TM simply create one backup file and then recognize new files to add to that existing backup? Other software?
And please, I don't wish to hear a comment about buying extra storage. I think it is idiotic to have a HD full of several dozen copies of the same files, with only a few hundred to diferentiate b/w each backup.
