I get it; distinct create and apply phases, with their particular
behaviors/needs.

I do mean that, yes.  I had the misunderstanding that the
destination file had to be in a state identical to the corresponding
destination file against which the batch was originally created, or
an update would not be applied.  Thanks for clarifying.


I see now how I came into this erroneous idea.  The man page says:

  ``The read-batch option expects the destination tree that it is
  updating to be identical to the destination tree that was used
  to create the batch update fileset.''

I failed to closely read the following sentences which explain
exactly what you've told me here.  Thanks for tolerating (and
graciously answering) a man page question.


And thanks for (maintaining) the software!  Like gajillions of
others these days, I have my backups based on rsync.  52 "snapshots"
of three different systems, spanning two years, taking 31 gigs, with
new snapshots added six times daily.  I couldn't feel any more
secure if I wore pants with both suspenders _and_ a belt.
