    Hi,

    I'm using TSM with directory stgpool, on client side I have some encrypted files that I would like not to dedup. Let's say I'm doing a lot of changes on them and backup them often, deduplication of this files load the server and dedup ratio is not satisfying (because of encryption). I know of course about exclude.dedup but this only work on client-side deduplication. Is there any way to tell server to leave this data alone and still using directory pool.

    The only way is if you switch to client-side dedup for that node.

    So if client side dedup will be in use, inline dedup will not occure?

    Ok, I think that it's not possible to tell tsm server to not dedup specific objects. Inline dedup is in use even if file is excluded from client-dedup. So I need to use nondedup stgpool for this files.

    I think you are right, it just prevents client-side dedup, but doesn't prevent server-side.

    I'm not sure I'd worry about it though. They would be stored in non-deduped containers anyway:

    It's up to you, but I'd leave it as-is. The simpler the better.

    have you tried just excluding the files using incl/excl statements?
