I have a customer who tried:
  incremental -verbose /ps/odstest/data
and several objects were inspected but not were backed up.

He then tried:
   backup -verbose /ps/odstest/data
and that backed up the two sub directories but no files.

Finally he tried:
  incremental -verbose /ps/odstest/data/
and that backed up the files.

Why (or when) does the ending slash make a difference?  He claims he
has similar incrementals on other machines that work without the ending
slash?  Is there a logical explanation for that?

The machine being backed up is running Aix 4.3.3 with the TSM 4.2.1.15
backup client.  The server is on OS390 2.10 running TSM 4.2.1.9.
