I don’t see where he contradicts himself. He’s saying newer stuff restores faster, but that the difference between yesterday and a week ago is “miniscule.” He also says that the difference between yesterday and six months ago is more substantial. That’s not a contradiction AFAICS.

JL;

In the prior post you wrote that: “The newest backups will always provide the fastest performance.” This implies that older stuff restores at a slower rate. You directly contradict that in this post. So that was the reason for my observation. If you are now stating that, unequivocally, restore speed is not impacted by age of backup being restored, then great! But that is not consistent with your prior statements.

Secondly, it is great that TSM Delta Stor is shipping now. From what customers tell me, it was about 18 months late. So a bit of a cheap shot. Well, a lot of a cheap shot. But true nevertheless.

Thanks for clearing things up.

Curtis,

Let me respond directly to each of your points.

TSM Deduplication
I may not have been clear in my post regarding TSM deduplication and so let me restate: DeltaStor support for TSM is GA.

Futures
It is my policy not to comment on unannounced products and so I purposely did not speak to replication and will not address your latest request for NetWorker GA dates. However, I can say that you should look for an announcement from us in the next couple of months.

If you would like to sign an NDA with us, I would be happy to provide more details.

I get it. When he said “just like TSM deduplication,” he meant you deduping TSM data, not dedupe IN TSM.

I did notice that you did not reply to the part of his post where he asked about replication. Did you think we wouldn’t notice? It is a major area of weakness for your product.

Can you comment on when the following two long-awaited features will be GA?

1. Delta Remote (deduped replication)
2. Dedupe of NetWorker data
