Hi Peter!

Sorry to bother you again. When you say "I only wished the system was a 
little bit bigger ", how much data do you get on to your DD200? With a 
compression by 18 you must get about 70 TB down on the DD200. On the other 
hand that is not so much if you want to keep a couple of weeks backups on 
disk, as you said "a little bit bigger" maybe had been nice...

I read this in the tech spec:
Useable Capacity Up to 23.4 TB virtual, 1.2 TB physical

What do they mean by 23,4 virtual and 1.2 TB physical?? What is virtual in 
this product?

Best regards,
