Thanks David, Bjoern for the great hints!
We are testing the self-signed certificates created by the server instance,
so at this stage, no third-party certificate is involved, using the dsmadmc
native commandline (no hub-server, no oc, no server-to-server, all down to
absolute basics. Using gskit
Hi all,
TSM deduplication is effective combined with compression. Without compression,
I'm not sure that it worths what it costs (1:2,5 ratio or 65% is what I
generally see with mixed data and "standard" retention).
You all should whatch this Tricia Jiang's video on YouTube (from 7:11) :

Just jumping into the cloud storage arena with tsm.
Just installed server 7.1.5 to experiment with cloud storage.
We have been mandated to replace our largely tape based environment with amazon
cloud storage.
I know very little of tsm's implementation of this, and how it may be used.
I see lots
Thanks.
TSM support also came up with this one as we logged the PMR. But
unfortunately, it does not apply to us, as we didn't delete the 'TSM
Server SelfSigned SHA key' from the certificate database.

Hello,
Correct, current client-side compression is not affected.
Spectrum Protect is targeting client-side compression integrated with
dedup and this new compression later this year.
Matthew,
Just a question : how do you know the size of pre-dedup data ?
Did you make use of backup reports on each clients to get that information, or
built some query based on dedupstats table, or anything else ?
Here again, I cannot seem to find coherent information in TSM output ...
Let's
If you are using node replication, you could re-replicate the data and get
it compressed (both ways). It may be a bit much work, feasible perhaps for
selected nodes.

Additional question : if replicating compressed data, will the data be
transmitted compressed or uncompressed ?

Hi,
but already client side compressed data isn't affected, isn't it?
what if data is replicated. Is that data then compressed?

No. Only newly stored data will be compressed.

After upgrading to 7.1.5 is there a way to get pre-existing container data
compressed?

Arnaud,
I too am seeing odd percentages where containerpools and dedup is
concerned. I have a small remote server pair that protects ~23 TB of pre
dedup data, but my containerpools show an occupancy of ~10 TB, which
should be a data reduction of over 50%. However, a q stg on the

Robert,
you run protect stgpool prior to replicate node. By doing the protect
first, you can reduce the amount of traffic needed for the replicate node
process. Also, without performing protect stgpool, you loose the ability
to use REPAIR STGPOOL as it depends on Protect Stgpool being performe
