Hi, Despite the fact that i agree in general with your comments, in reality it all comes to money.. So in this case, if i could prove that ZFS was able to find X amount of duplicated data, and since that X amount of data has a price of Y per GB, IT could be seen as business enabler instead of a cost centre. But indeed, you're right , in my case a possible technical solution is trying to answer for a managerial solution..however, isn't it way IT was invented, that i believe that's why i got my paycheck each month :)
