Networker Server 7.6.3 , Capacity Licenses Query.

To add to it , i would also like to know for how long does this capacity 10TB can be used, i.e whether i can backup 10TB to my backup server every month ? or is it some other way around ? Kindly assist and enlighten me.

Let's say you run mminfo to see how much data our protect and answer is 9TB - this is covered by 10TB license.  After a week you may have 2TB more, but you also expired 2TB due to retention (ideally) so you are still protecting 9TB which is covered by 10TB license.

Abhishek,

   Go ahead and check this - https://support.emc.com/docu48341_NetWorker_8.1_Licensing_Guide.pdf?language=en_US

That means just these 3 licenses would be good enough to run all the features i need, and Sorrie but did not get the Capacity license explanation

My name can't be pronounced - that's why I use it as password.

For 27TB to be protected at any point in time, you need 27TB or more capacity license.  I really don't know what happens if you exceed such limit - I never have seen that in practice.

One thing I wonder is what happens if you replicate data?  For example, if I use DDBoost, then NW is aware of the copy and 20TB becomes 40TB.  Does license cover primary data only or the copies as well?  In such case, if I do replication outside NW, then I still have the copy (though not backup application aware) and I license only 20TB instead of 40TB.

Let's take step further and step into philosophy land now Let's assume only primary data is licensed with excuse that secondary is the same data already licensed and copy as such is already covered by license used by disk appliance (for example).  One could turn table and state that in such case, where de-dupe is used, only raw capacity of such disk appliance should be covered by capacity license as multiple parts of primary storage backup are seen as single instance and ability to serve such de-dupe approach is something that comes from disk appliance and not backup application (therefore licensing should be focused on capacity of the target and not source).  To my knowledge, this may happen in future, but this is not the case right now. Licensing is dirty business - that's why I stay out of it.

Dear Hrvjoe/All,

I am using Networker 8.0 with DD670. Which value should be taken for calculation of capacity licenses ? For example, backups on DD show size of 1.3 TB but the actual client size is much larger. Which one should be taken into account for calculation?

https://emc--c.na5.visual.force.com/apex/KB_BreakFix_1?id=kA1700000000WLS says

"

Capacity licensing model:

With capacity licensing, you can deploy unlimited quantities of the NetWorker options and modules to protect up to the amount of licensed capacity. 

The capacity licensing model is price-effective for backup environments that:

• Contain a large number of backup clients, where the average data per client is 250 GB or less. The backup clients can include physical clients, virtual clients, deduplication clients, and application clients.
• Deploy advanced backup technology, such as:  Deduplication, Disk backup, Microsoft applications,  Oracle, other application and modules, and VTL backup "

whereas https://emc--c.na5.visual.force.com/apex/KB_BreakFix_1?id=kA1700000000Tqh says

" "Data is measured as the largest aggregate full backup or synthetic full backup which is the combination of full backups plus incremental backups that are performed for all protected data by the NetWorker software over a two-month period (60 days). This is irrespective of where the data is backed up, for example, from tape, disk, VTL, Avamar ® Data Store, or Data Domain. The quantity of pre-deduplicated data is included in the calculation."

I am confused between the two, is the deduplicated backup data to be considered for license calculation?

First link is blah blah and second one gives you an idea what EMC vApp is measuring to check if you are compliant with capacity license. Rule of thumb is (or at least it was), that EMC will convert your licenses to capacity in a way that you get at minimum what you already had.  Remember, in world of big data, volume of backups will grow so in long run there will be return of interest for sure I don't use capacity model so I don't know for sure, but if they use mminfo then I assume capacity model does not take into account de-duped values.  However, while that might sound Woopsie, it is also true that price conversion model from legacy method (and capacity) to new one is not 1:1.  In other words, check what you have, talk to EMC and have a offer, put it on paper and do few calculations.

Thanks Hrvjoe,

Yes we do use mminfo..

Ok...I will talk to EMC
