TSM is *very* different to NBU. One big difference is that it works on a
forever-incremental methodology. Although I believe these days it is able t=
o
work in a Full/Incremental fashion as NBU does, just as NBU is now able to
do synthetic backups, which is similar to TSM.
There's also a fairly large housekeeping overhead with TSM. You need to run
"tape reclamation" to kind-of defrag your tapes, run catalog reorgs, and
that kind of stuff. But if you have it all setup correctly and keep up with
the housekeeping, TSM can be much more efficient than NBU.
Expect a steep learning curve, especially for someone who is used to NBU.
A big factor for TSM is that it's based on mainframe software (DFHSM) which
has been around for .... 30 years or more? So it's fairly reliable. IBM hav=
e
been doing this kind of thing for a loooong time now. In some ways, NBU has
"grown up" from the single server, few clients, single tape drive days,
while TSM has "grown down" from the old mainframe with dozens/hundreds of
local tape drives, to today's decentralised world.
Which is better? I don't know. I haven't touched TSM for a long time. They
both have their pros and cons.
Could you run both for a while and see how you feel after a few months?
