    I just got my new Imac about a week ago, and got time machine setup with a 1.5tb external drive. i only have 80 gb used on my primary drive, and in a week TM has eaten 500gb of my external, the thing does several backups a day and each is around 10-16gb.

    why does it back up some much stuff all the time? shouldn't it only be backing up files that change? seems like a major waste of space to have 100 copies of the exact same file.....

    Partition your external and give it like 500GB max so it won't eat the whole HD. It deletes the old backups when it has filled the partition

    It runs every hour and backs up any files that have changed. Do you use VMWare Fusion or Parallels?

    Yes, every time you change anything in Fusion, it will backup the entire VM.
