Bill,

Does your options file have INCRTHRESHOLD specified with a non-zero value?
I suspect that this is the case, and this is why you are seeing the
(normal) behavior below.

When long file names are deleted, Windows may report this to the journal
service with a short name. Since the short names are not stored on the TSM
server, they can not be used to directly delete the object from the TSM
server. Also, short names are not unique, so they could be reused; in
which case the deletion notice stored in the journal may no longer
identify a unique object.

Instead, the directory in which the deleted object is contained is stored
in the journal. After the incremental completes for the file system, full
incrementals are performed for the directories containing deleted objects.
In this fashion, the deleted objects are expired from the server.

Check out the reference information for INCRTHRESHOLD in the "Using the
Backup-Archive Client" book. The redbook "Tivoli Storage Manager Version
4.2: Technical Guide" also discusses how journaled backup works in a bit
more detail.

The only dumb question is the one that goes unasked.
