Veritas recently commishioned a "study" of performance between Netbackup, 
Networker, and TSM to compare results of snapshot backups.  Apparently the new 
Netbackup 5.0 has a new "advanced client".
For TSM, they threw it in stating that there is no comprable feature, but they 
wanted include it anyway.  I have never done any investigating into doing 
snapshot backups of data with TSM, do any of you do anything similar at your 
site and if so, what?
