TSM replicating from CONTAINER to FILE - is it supported?

[mirrorsaw]

Hi all,
We've recently started using node replication across our TSM servers and the ones running traditional FILE devclass pools are working great (replicating to FILE at the other end), however our newer servers which use containers are struggling to replicate over to FILE. It's taking several hours to replicate 1GB of data. My guess is that a heavy conversion is taking place, but is this a supported method and is there anything I can do?

Is it only data which not duplication will be replicated right?

You can replicate any data, however if the target is not deduplicated, the data will be rehydrated before during replication.

And what's about compression during replication?

I'm not sure on this one.

You gave me a pretty firm 'no' there, but I've just read this IBM technote:
http://www-01.ibm.com/support/docview.wss?uid=swg21978041
Which says " It is perfectly possible to replicate objects from a source container pool to a target traditional VOLUME based storage pool (such as tape)".
What's the deal?

My mistake. You are right.

The conversion you are talking about in your initial post is that the data is deduplicated in the container pool, but it suspect it gets rehydrated when you send it over to a non-container pool at the target.

Umm did you delete the comments where you gave me incorrect information? Isn't that abusing your moderator powers?

I deleted the incorrect information so that someone doesn't use that information as being correct without reading the whole thread to find out it was wrong.

I was not trying to hide the fact that I was wrong, I don't want people using wrong information and then make wrong decisions based on it.
