when directory is moved, TSM backs up is contents... again

We have TSM 6.3 running on the server, and clients with GPFS filesystems that we are backing up.

The problem is that a user can do a move (or rename) on a directory, and the whole directory will be backed up again. For example, let's suppose does a :

mv /lb/projects/projectA to /lb/projects/Project01

Then TSM will re-back up all the contents of /lb/projects/projectA as /lb/projects/Project01.

Is there a setting we can do to avoid this?

Thank You,
