We have a retention period of 2 weeks on our SQL2008 environment which is 
dumping directly to our DD670.  A quick check of our current stats show we are 
getting 34.02x compression on the contents of this directory.  In theory 
compression will get better the longer you keep the data.  We don't have a need 
for more than 2 weeks worth so that's all we keep.

I can probably get some more specifics regarding the amount of data being 
backed up etc.. if that would help any further.

To all,

I am interested in finding out what deduplication ratios users are seeing when 
backing native SQL dumps to a Data Domain array? 

Having friends who work for EMC, they say 3:1 to 4:1, but I am looking for real 
numbers that users are seeing not the sales numbers.

Please let me know
