I depend on secondary storage and the Volume snapshotting utility to 
backup important VMs, but if you want more than that, you'll want to do 
something like backup your secondary storage to tape or a tertiary disk 
storage volume.  But I also run dual active-active SAN, so my vm data is 
already on two different SAN nodes at all times, PLUS a secondary 
storage backup
