Hi Eric,
I just can second this! Just thinking of that kind of restore makes me
shudder! This should be much worse than a restore without collocation and
about the same like a restore with a multiplexed backup. And think about a
parallel restore of two, three or more clients, each competing for the same
file on the same tape but to different times...
This feature is definitely one I don't want to have and I don't need to
have!! Then I'll rather buy some more tapes!
Mit freundlichen Grüßen,
Met vriendelijke groeten,
With best regards,
Bien amicalement,

Hi Steve!
Before we used ADSM we used Legent's ESM (now I believe it's called
CA-ESM).
ESM also stored one copy of each identical file. Believe me, you do not
want
that. The first (and thus only) copy of winword.exe is definitively stored
on a different tape than the rest of the clients data. This kind of
duplicate backup data elimination causes the data to be scattered across
numerous tapes. I know this from experience. This is one of the reasons
(the
other reason was that the product was buggy as hell) we migrated from ESM
to
ADSM a few years ago.
Kindest regards,

I'm not an expert with ADSM, but does ADSM have any of the advanced
features that this article talked about? Can it back up a file only once
for all the computers that have a copy of it? Or will it back up
Winword.exe 5000 times for my whole organization?
We're starting to look at what it will take to offer backup for the
entire campus, and some of these advanced features would be desirable.
