OK, I've been working with TSM (ADSM) for about 6 years now and you can
call
me cheap but I never (personally) though DRM was worth the money.  We do
operate in a unique environment here so I shouldn't say that DRM has no
place in the market, it is just that I was doing DRM before DRM came out
and
once it did I couldn't justify the cost just to replace all that I had
done
over the years.
We don't really run with copy storage pools... our TSM servers are located
offsite to the production boxes that they backup so backups are
effectively
"offsite" as soon as they are created.  We also deal with so much data
across our 10 TSM servers on a daily basis that we would have to make them
20 if we were to copy all the data on a daily basis, and that just isn't
going to happen.
Now what sort of disaster am I protecting against ?
Total loss of environment due to hardware failure.  Not really counting
fire, flood, water, etc...
If my actual server goes dead, AS LONG AS I HAVE MY ATL, well at least the
tapes, I'm OK.
So to answer your question, almost yes.
You need your db backup (from tape, disk, somewhere), you need definitions
of your data base & log files (I always allocate them the same size as
they
were), the device configuration file is nice (just about necessary).
With that info you can get back your environment as long as you have your
tapes.
