I do not think you understand.

If you are running a journal service you do not need to use incrbydate.

To do what you are trying to do you need two separate backups.  The first
is a periodic image backup, maybe once per week or once every two weeks.
The second is a normal incremental backup, which you run daily.  Because of
the journal service this should not take very long after the first time.

Now the advantage is that when you come to restore the whole disk, TSM can
restore the most recent image, and then using the incremental backup
restore those files which changed after the image was taken.  This is much
faster than restoring each file individually from the incremental backup.

To run your test, you need to run an incremental backup.  This will set up
the journal database ready for changes.   Then run an Image backup.   Next
make some changes and finally run a second incremental backup.

Format your test disk.  Run the image restore using the gui and select the
"Image plus incremental directories and files" option. See page 107 of the
5.3 Windows BA Client manual for details.   The image will be restored and
the changes applied from the subsequent incremental.

Try it and let us know how it works!

I added a new directory with 40MB of files in it. This directory is a new
one that was not present when the image backup was performed. I think the
most rudimentary task that is expected from an incremental backup is to
understand newly added files and directories.
