Paul,

      If moving from a dedup pool to a non-dedup pool, the objects are
re-expanded and stored in their entirety again.

Thanks,
Colin

  Subject:    [ADSM-L] TSM 6.1 dedup on SERVER devclass






Hi all,

I am already aware that TSM 6.1 dedup feature works when the data is stored
in a FILE devclass, and is "re-built" when the data goes to tape. But I
have a question: If the data is migrated from a FILE pool to a pool with a
SERVER type devclass, would dedup still be in effect?

And is dedup also valid for COPY pools (as long as they are defined on FILE
or SERVER devclasses)?

Thanks,
