I use TimeFinder with the FDRSOS product for those open systems that are
larger than 60 GB.
Works much faster than using net work to back up that much data. The
backup cycles are all on MVS.
Not sure how you would use TimeFinder with ADSM.

Since some are using EMC DASD, and it appears that you are looking for a
centralized backup product (and assuming that you have a mainframe??),
another option to review is the FDR/Upstream/SOS product. The product uses
the EMC DASD as a conduit from OpenSystem to mainframe at SCSI/ESCON speeds
without clogging the network. And with the EMC Fibre Channel connects,
it's
worth consideration!!
