I'd like to use a single 2tb drive for time machine backups and run vmware machines off of. Is this an OK idea? Anyone see any problems or limitations with this? I will also use an older drive I have laying around to clone the mac HD about once a week. One limitation I thought of is if the drive fails I lose my backup and the virtual machines. Is there a way to get SuperDuper to include the partition with the machines in the clone?
