And, how nice it was of Tivoli to set the default of that to "no".  That is
probably my problem.  I will make that change to all the Netware servers on
Monday (never change things on Friday unless you have to).  Thanks for that
little tidbit.

Ahhh, Netware - check the value of the tsm option "NWIGNORECOMpressbit".
If
set to no, then tsm will rebackup the file when netware compresses or
decompresses the file.

I had considered that, and honestly, I wouldn't know how to tell if the
permissions had changed on the days in question.  I don't see why they
would have changed.  There are other files in the same directory that have
their only backups on the same day as the oldest backups for these files in
question (the day this node started backing up to TSM).  Yet some of the
files have had additional backups when it doesn't appear to have been
necessary.  We don't normally set permissions at the file level (this is a
Netware server).  Plus, some of the files in question wouldn't even have a
need to be accessed.. things like Ghost(R) files and old archival type
documents.

It really boggles the mind.

Did the permissions change on the file or owner or group?  If any of these
change, TSM will take a new copy of the file as if the file had changed.

Does anyone else see this issue?
I have seen several instances where TSM backed up a file when it had not
been modified in anyway.  Even when you look at the restore application,
there are several versions of a file, each with the same create date, the
same modified date, and different backed up dates.  I am curious if others,
or everyone sees this happening, or if I have some setting incorrect some
where.
There have been no "always backup" backups (selective) performed, so that
isn't what happened.

Clueless...
