Thanks for the Tower of Hanoi reminder.  I used that many (many) years ago with 9" tapes on a Big Iron machine but had forgotten the technique.  I’ve been using a FIFO seven-day rotation backup of my main user directory (using CCC), but I’m going to reconfigure it to get the longer backup “tail” provided by the ToH approach.
