I have a question regarding collocation.  We incrementally backup 20+
machines nightly that are running a flavor of Unix (CLIX) not natively
supported by ADSM.  This is done by NFS mounting their drives, one
machine at a time, to an AIX machine (AIXA), and then running a backup
of them from AIXA.  AIXA then owns the backup information for the CLIX
machines.  The backups of AIXA are run by userid root to an MVS server
and collocation is enabled.  Since the backups are all run from AIXA
using one userid, collocation causes backups for the 20+ machines
to be grouped together on tape.  This is messy when a restore to one
of the CLIX machines is required due to lots of tape mounts.  The
question is this:  if we used a unique userid in backing up each of
the CLIX machines from AIXA, would collocation then spread the files
across different tapes based on userid, or will it keep them together
because they are all from AIXA?
