We are using DeDupe from Data Domain in our TSM 's (5.5) and a lot king of 
backup's Windows , Linux , OES, Oracle , Exchange (TDP), SQl (TDP) , SAP (Rman) 
....

How ratio is almost 9.

In a few weeks I will at least move one of our TSM server (windows) to V6.2.1.1 
and I will be pleased to hear about DE duplication on V6

Regards Robert

I'm curious what others are seeing for de-dup ratios for various methods.

We're using IBM's ProtecTier for our TSM (5.5) primary pools and only see about 
a 4 to 1 ratio.  This is less than half of what IBM was projecting for us.  We 
have roughly 400 clients (mostly Windows servers) totalling about 135TB of 
data.  Biggest individual uses are Exchange and SQL Dumps.

Just wondering what others might be getting for other appliances or with TSM v6?

Thanks
Dave
