Recently I upgraded the RAM on my MacBook Pro and did a fresh install of Windows 7 using BootCamp. I partitioned 200MB out of my 500MB drive to be for Windows 7. I then had VMWare Fusion setup the partition to be used from within it.
Since I've done this, I've noticed that Time Machine is running a lot more frequently. When I click in the taskbar to view it's status, it often says it is backing up approximately 5GB of information at a time, or processing about 2000 files at a time.
Sometimes I let the process finish, sometimes I tell it to stop because it starts to slow down the machine a little (since I'm doing heavy development work both on the Virtual and the Physical machine).
This leads me to believe that Time Machine is backing up my Virtual Machine in addition to my Physical Machine. Is this correct? Is there a way to prevent it? I plan on using Windows 7's own backup tool for the virtual machine.
