I am reading the same description of how Time Machine works but it's not really answering my question.
Right now I have 300GB of data on my MacBook Pro and want to get it backed up on my external HD and much of it deleted from my computer. My exHD is 1TB.
From what I'm understanding TM's making multiple backups, which means I'm going to run out of space pretty fast. That doesn't make sense to me so I'm assuming I'm misunderstanding and it's only backing up CHANGES made to files, not backing up every dang thing multiple times, is that right?
But what if I want multiple changes backed up? Is it only keeping the most recent change of the day/week/month or multiples?
I do NOT want TM to delete my old backups, but can't seem to find out how to have it alert me BEFORE I'm running out of space (versus automagically erasing my things like photos that I may only want on my external). Is there a way to turn off those auto-deletes?
I'm coming to the conclusion that TM is great for continuous backup but not for long-term storage, since it deletes long-term storage. Am I right in this or am I missing something?
If this is the case and my exHD is already being used with TM, can I turn TM off and backup only my updates in some other way, or is it already formatted for TM and I'll need to reformat it and do it manually? (Such as copying things over and having it ether replace or make a second copy of things as it goes according to what I want it to do.)
I hope all this is making sense because I feel like I'm talking myself in circles.
Thanks in advance,
Tara
