I've been having Time Machine telling me that my 1G backup drive is full just about every day since I told it to back up my VMs. Is the VM a SparseBundle? Does Windows change too many things anyway? I also tried to reload a VM from backup since my attempt to delete a snapshot locked it up and I can't get back in. It gets about half-way restored when it tells me the file is being used. Not by anything I can find.
