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,

CU/2,

Hi Steve!
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,
