[QUOTE="MacInWin, post: 1631193"] Welcome to the forums, Sofia! It would have been better for you to start a new thread instead of tagging on a 4 year old one, but for now, we'll work with it. Why do you think TM is making a full mirror image on the external HD? TM doesn't do that by default. What TM does is to make a full backup the FIRST time, then only changes what files have changed after that. The interface is designed to let you think you are seeing all of the original files, but that's just how it presents itself. The actual backup only contains the changed files. For example, on my machine I use TM to backup my internal HD. The HD has 300GB of data, the external HD for TM is 1TB with 700GB in use. I just counted and there are 65 backups on the external, so it obviously is NOT backing up an entire image, but just incrementals. So, again, what makes you think TM is making full mirror images every time? [/QUOTE]
