I don't think this answers my question.  We are putting bout 260GB per
night into the storage pool.  My sequence of processes is to backup the
disk pool to copypool. migrate, backup the tape pool to copypool in case
I missed anything, then backup the database.  I understand that each
process is not limited to one node, so then why are the first three
processes ending so quickly?
