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.

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.
