I've been using Time Machine successfully since it became a part of Leopard. However, since upgrading to Snow Leopard 10.6.2, Time Machine has been a problem. The same external firewire drive that I have been using all along seems to unmount and the Time Machine backup fails. TM worked okay in Snow Leopard up until 10.6.2. I tried a different drive and am experiencing the same problem.
