Deduplication ratio

You will find good information in this thread:

Might I ask what you are also looking for in that output? To see how well individual backups are deduping yes or no? And then acting upon it if dedupe is not that good?

However this will not give you insights on how much data a client in total is occupying on a DD, that is something we try to achieve using some DPA reports about NW clients, that are to be enriched with data collected from the DD systems through DPA, however results are not yet that positive. Also to be combined with current Dell DPS licensing method that is using front end protected capacity (largest backup in a 60 day timeframe) to determine license costs.

It is already long overdue that Dell makes live easier so to be able to report about actual disk consumption of NW clients so that billing might better reflect this. Clients that have bad dedupe (either high change rate, encryption, compression) should have their backups cost more than clients that dedupe very well. Now one is still mainly stuck with retention time as a cost factor, whereas ideally you would use different billing method as deduplication is a whole different beast altogether, not really fit for using methods of old.

one can imagine for example that if data dedupes very well, that it might not even matter to keep longer retentions as underlying costs with dedupe would not increase as much compared to making backups to tape (or non-dedupe disk based solutions).

thank you, we dont have ddboost in the system, I think that is why I dont see dedupe statistics

thanks you are absolutely correct
