    I upgraded to Mountain Lion on Thursday. I had a complete Time Machine back up of my Lion system done right before I began the upgrade. After that, I had a few successful back ups doing only what was new. Now my Time Machine has started a 458 gb backup- my whole computer! Any ideas what the heck happened?

    Your operating system changed, so it's doing a complete backup with your new operating system.

    I don't think that's it, because mine didn't. First backup after ML was 56GB of 450GB, and 30+GB of that 56GB was virtual machine disks.

    It didn't do this when I upgraded to Lion.

    Ugh, still can't back up. It errors out constantly. I have been backing up to a NAS. How the heck can I take that setup to the Apple Store to show a "genius" what's wrong? Overall I love ML, but this is kind of a big deal to me if Time Machine won't work.

    Same Problem.........!!!!

    I've got the SAME problem. My Mac Mini is backing up like 33GB each time I sign in each morning, not just a small incremental backup. Please help with this? Otherwise I just need to turn it off. I recently installed Parallels 7 (now 8) and it did a full backup over a week ago, but still seems to be backing up like 33GB or so each time I sign on in the mornings or whenever I'm on it.

    I finally managed to get through one full back up, now twice my computer has told me that it needs to reback up and I've suffered through 2 more total backups, for a total of 3 total back ups nearing 500 gb since I've upgraded to Mountain Lion.

    I didn't think TM supported NAS? A quick google found a bunch of issues, such as this http://trick77.com/2011/07/15/about...achine-compatibility-netatalk-gpl-violations/

    Well I am using a Buffalo NAS which has Time Machine enabled and I had not changed any settings so far. I think my Macbook Pro laptop is backing up fine, but it's my Mac Mini that keeps wanting to backup a hundred times a day and a huge amount of data. I thought Time Machine was automatically setup for incremental backups on changed or new files?
