Enable Deduplication Licensing Doubt

[marciobastos]

Hi there.

In our company, we are evaluating the use of the Deduplication feature that we have and we came across certain doubts about the licensing of such feature.

Overall, we have an environment where the Staging area for the dedup is around 40% of the total environment covered by netbackup, which only allows us to keep around 3 days worth of data there. Due to this restriction and to the way our policies are, when checking the results of the "nbdeployutil" show that, in the majority of the cases, no Dedup is applied at all.

In that case, it means that, even though data is not being deduplicated, we still need to license the full size of each single client? (100% of the supported environment).

Many thanks,
Marcio.

If you only have space for 3 days, then there is honestly not much of a point in implementing Dedupe. Dedupe is only useful when you have 10 - 14 days of backup on disk. 

If you are backing up all clients to dedupe storage, you need to calculate the data on all clients for dedupe (DPOO) license. If you will be backing up 50% of clients to dedupe storage, you only need to add up data on those clients for DPOO license.
