I would continue to use ext3 filesystem managed by lvm2 - but I'm not real familiar with the ZFS solution. lvm2 has worked very well in my experience and can expand an ext3 filesystem without unmounting it.
Since you're using rsync - you might want to take a peek at rdiff .. essentially allows incremental type backups using rsync. But since you're using TSM, you may already have an incremental solution.. fwiw.
