Dbcopy Rsync - still bloating

I'm using a modified version of this https://forums.novell.com/novell-product-discussions/collaboration/groupwise/groupwise-2012/gw2012-install-setup-admin/455580-dbcopy-restore-question-post2195713.html#post2195713

The size of my Live system is 100Gb
but the Restore Area / backup is 130Gb

are there files in folders other than po/offiles/ and po/ofuser/index which need to be removed ?

NB: I did apply this script after my restore area was already bloated by dbcopy overtime
