A few months back I wrote for Download Squad that Time Machine, Apple’s new backup utility, was the single-best new feature of Leopard. And I still believe that. But it does have a few shortcomings. For example, it would be nice to set aside ‘quiet times’ when the automatic hourly backup can be programmed NOT to run.  For example, if I’m in the middle of a recording session and my USB 2.0 Maxtor drive starts Time Machining like crazy, it has a tendency to make my recording software (GarageBand and Logic Express) go a little haywire.  So I find myself going into Time Machine preferences and turning that magic switch to “off”.  Of course, I often forget to flip the magic switch back on again.
