TSM on NT works well.  TSM on W2K works even better.  A lot of the new
development going forward is actually on Windows servers so it may exceed
UNIX in terms of functionality.  For smaller environment I would recommend
TSM on an W2K server, but for large environment backing up at least 1TB a
day or more, I have to stick with AIX or Solaris for my TSM server.

Just my $.02
