The thing to remember is that TSM is an enterprise oriented solution.  The
assumption is that your infrastructure and procedures prevents full box
restores from happening very often at all and that you have too many boxes
or too much data to push full backups every week (or whenever).  It is
definitely slower on the restore than the full/inc/inc backup schemes, but
in a stable production environment where you don't have to recover servers
every other week, the automation and ease of management definitely outweighs
the slower server recovery of TSM.  IMHO, anyway.
