Becky,
yes, it does. Data that are backed up either by brbackup or brachive are
stored as archive objects in TSM database
and they are deleted when eligible, thus freeing up the tapes.

I don't know of any issues during disaster recovery, when using TDP
versioning. The only thing that you should be aware of is
either using TDP versioning (and having retain version set to nolimit or
9999) or TSM versioning only.
