I have been involved with several, ADSM/TSM, Veritas' NetBackup, LEGATO etc.

What do you want.  A rudimentary backup utility (that comes with its own set
of problems) or a true data/storage management system.

If you are trying to relieve your problems and headaches, my advice is to
stick with TSM and learn how to use the product to fit with your
organizations requirements.
