[ADSM-L] What to dedup.. was "TSM being abandoned?"

 
Hi,

Isnt dedup most beneficial at deduplicating databses ex. Oracle and
Domino etc...? No pre-compression or encryption.
Even Data Domain dedup thoose types av data pretty well.

But I tend to agree with your opinion about performance.

We look at dedup VTL as a possible target for active storage pools
containing ordinary file backup. This way we don't risk very much if the
VTL breaks or the VTL's dedup index goes corrupt. I am a little
sceptical about the robustness of these products so I will not let these
VTL's play a too significant role in our setup. My sceptisism may of
course be totally unfounded.

For TDP-data which are written and read in large sequential chunks, tape
is just fine performance and cost wise. From what I have heard, it can
be hard to obtain any decent dedup compression for Oracle with dedup
VTLs and the performance is questionable.




Best regards

Hans Chr.

A VTL vendor said he is seeing a number of mid-sized businesses
migrating from TSM to NBU (Symantec). Do you think this is true? My
concern is that the pool of support techs will shrink and put us in a
bind.
